We in the North don't see much of the Pitcairnia family. Although there are a number of species small enough to fit into our bromeliad collections, they are not very interesting when they are not in bloom. But because the family is so distinctive in several respects, it is well worth exploring. I have presented a brief survey which will, I hope, pique your interest. The May meeting is at Paul Wingert's shadehouse. There is much to see – in addition to recent acquisitions, the new batches of his hybrid seedlings are coloring up. The visit to the shadehouse is an enjoyable initiation of what we hope will turn out to be summer. Next Meeting: MAY 18, 2013 Our next meeting will be Saturday, June 16, 2:00 p.m.at Paul Wingert's shadehouse (up the hill behind the house), 27276 Edgemoor, Farmington Hills.

An exciting opportunity to spice up the new growing season! Pitcairnia by Penrith Goff Pitcairnia , L'Héritier 1788. This genus, named for a British physician, Dr. William Pitcairn, comprisies over 300 species, is second in size only to tillandsia. Pitcairnias are widely distributed in Central and South America, prefer moist areas and are mostly terrestrial. Some grow on rock (saxicolous) or as epiphytes. Most of them, with their long narrow leaves, look like a kind of grass, reminding us that bromeliads are one of the 16 families in the Poales, the order of blooming plants to which grasses, grains, and cattails belong. When they bloom however, it becomes dramatically clear that they are not grass. The flowers are usually shades of red, yellow, or white, matching or contrasting with the bracts from which they emerge. P. albo-lutea P. atrorubens P. chiapensis There are also shades of violet: P. carnososepala P. andreetae P. rubronigrifolia Secund inflorescence: the flowers often grow on one side of the stem (rachis). P. stenophylla (left), P. corallina (right) P. heydlauffii: Herbarium Page and Habitat Photo: A Typical Pitcairnia A typical pitcairnia: long grassy, often toothed leaves, spiny growth (A) at the base of the plant is actually leaves modified as spines (B) With some pitcairnias first shoot growth is stiff and spiny, later leaves soft and grassy.

Guests very welcome! While the picture implies that Lynne has other plants and bromeliads, her specialty is really cryptanthus. She has a sizable collection of beautifully grown crypts and a large store of information about them and how to make them flourish. It is always a pleasure and an inspiration to view Lynne's collection. CRYPTANTHUS The genus Cryptanthus was established by Otto and Dietrich in 1836. The genus belongs to the Bromelioideae and comprises some 60 species, from which several hundred hybrids have been developed. Cryptanthus are prized for their foliage rather than their small, usually white, flowers, which are typically nestled, "hidden," in the center, hence the name: cryptos+anthos (hidden flower). HABITAT: Cryptanthus are terrestrials, indigenous to the dry forests of eastern Brazil. Most grow in shady moist areas, some (saxicolous) grow in rocky terrain, a few grow in full sun. They are dependent on their root system for water supply, and do not tolerate standing water in their centers and leaf axils. A very few ( e.g. C. warasii, C. glaziouii, C. microglaziouii) are succulent and can store water in their leaves. CULTURE: Cryptanthus produce their best color in strong light; however prolonged exposure to the sun should be avoided as a general rule. If they begin to redden unnaturally or to bleach, light should be reduced. They tolerate low temperatures but their preferred range is 60° F to 80° F. Fertilize during the months of active growth. Pups are produced prolifically from buds at the leaf axils. Pups are often produced even before the plant flowers. Some species produce a mound and pups fall off the top, taking root where they fall. Because Cryptanthus are moisture-loving and not vulnerable to fungal problems, they are excellent plants for terrariums. CULTURAL PROBLEMS: Rooting the pups is often difficult. They can survive for months without rooting but eventually they must root in order to grow. If they do not root under humid conditions, bottom heat may help. CHARACTERISTICS: FORM: rosette, usually flat and close to the ground but in some species (C.scaposus, C. pseudoscaposus) a short stem is formed which bears flowers at the top. SIZE: from a few inches (C. microglaziouii) to over 3' in diameter. LEAVES: many narrow leaves tapering to a sharp point. A few species have spoon-shaped leaves which have the appearance of being carried on a petiole (leaf stem). Several species have very narrow, even grassy, leaves (C. maritimus). Leaf edges are usually undulated and armed with fine teeth. Leaf undersides covered with scales (trichomes). Leaf Color: green, pink, red, maroon, chestnut, near black. Leaf markings: longitudinal stripes, transverse banding. Leaves of some species are succulent. INFLORESCENCE: nestled low in the center of the plant. In a few species (C. scaposus, pseudo- scaposus) the inflorescence rises some 6" above the rosette. FLOWERS: three sharply pointed narrow petals, white. Neither showy nor fragrant. FRUITS: seeds are borne in berries. PUPS: grow from the leaf axils and break away readily from the mother plant. A few species bear pups on stolons (runners). C. sinuosus 'Cascade' produces numerous 24-30" stolons, covered with bracts (modified leaves). NOMENCLATURE: aside from tribute to persons, the specific names given to cryptanthus most often describe qualities of the leaves : bivittatus -having two stripes ; brevifolius - short leaved; coriaceus -leather-like; crassifolius - thick leaved; lacerdae - tattered; latifolius -wide leaved; marginatus -having margins; zonatus -having zones, i.e. bands; teretefolius – terete leaves, pseudopetiolatus – looking like the leaf has a stem, Leaf color : argyrophyllous – silver-leafed, aurantiacus -orange, carnosus -pink (i.e. meat-colored), fuscus- dark, dusky, viridis -green, viridovinosus – green and wine-colored Growth habit : acaulis -stemless, bromelioides -like a bromelia, scaposus -having a scape, sinuosus -sinuous, winding Location : maritimus -at the sea coast, bahiana – Bahia, Brazil You've read this far? Here's your reward: Cryptanthus vexatus. As far as I know vexatus is Latin for annoyed, troubled, vexed. The FCBS photo index shows a plant which is all of that:.

GOUDA1 & RICARDO FERNÁNDEZ G.2 1Botanic Gardens, University of Utrecht (U), Budapestlaan 17, P.O.Box 80162, 3584 HD Utrecht, Netherlands. E-mail: [email protected] 2Universidad Nacional Mayor de San Marcos (USM), Museo de Historia Natural, Casilla 14-0434, Lima 14, Peru. Abstract A new species of Pitcairnia subgenus Pepinia (Pitcairnioideae) is described and illustrated here. Pitcairnia floresii sp. nov. has been found in the Department San Martín of Peru and is locally abundant. Key words: Flora of Peru, Pepinia, taxonomy Introduction This remarkable new Pitcairnia species with linear-lanceolate leaf blades and its red inflorescence with bright yellow flowers is rather common in the Central Huallaga River Valley area. The famous collector Richard Spruce was in this area in 1855 (León et al. 2003: 112), but as far as known no specimen of this species was preserved, nor was it collected afterwards. Another Pitcairnia, P. calatheoides Smith (1937: 24) has been described from the very same area, but is not closely related. The latter species has very long petiolate oblanceolate leaf blades and large orange petals. Mr. Alberto Flores, a farmer from Pucacaca, brought this beautiful species to our attention. From our study of Bromeliaceae of Peru several new species were recently described (Gouda & Manzanares 2008, Gouda 2012). The descriptive terminology of Scharf & Gouda (2008) is followed here.

  • Bromeliads Bromeliads Are a Family of Plants (Bromeliaceae, the Pineapple Family) Native to Tropical North and South America
    A Horticulture Information article from the Wisconsin Master Gardener website, posted 19 March 2012 Bromeliads Bromeliads are a family of plants (Bromeliaceae, the pineapple family) native to tropical North and South America. Europeans fi rst found out about bromeliads on Columbus’ second trip to the New World in 1493, where the pineapple (Ananas sp.) was being cultivated by the Carib tribe in the West Indies. The commercial pineapple (Ananas comosus) is native to southern Brazil and Paraguay. After the colonization of the New World it was rapidly transported to all areas of the tropics, and now is widely grown in tropical and sub- tropical areas. The only A collection of bromeliads placed on a tree at Costa Flores, Costa Rica. bromeliad to occur north of the tropics is Spanish “moss” (Tillandsia usneoides). It is neither Spanish nor a moss, but an epiphytic bromeliad. It doesn’t look much like a typical Commercial pineapple, Ananas comosus, bromeliad, though, with its long scaly stems and reduced in the fi eld. fl owers. Bromeliads are monocots, many of which, like their grass relatives, have a special form of photosynthesis that uses a variation of the more usual biochemical pathways to allow them to use water more effi ciently. Even though they come from the tropics, this helps those that are epiphytes contend with life in the treetops where there is limited water and a real danger of drying out. There are about 2500 species Many bromeliads are tropical and several thousand hybrids epiphytes. and cultivars. Many have brightly colored leaves, fl owers or fruit, and range in size from moss-like species of Tillandsia to the enormous Puya raimondii from the Andes which produces a fl owering stem up to 15 feet tall.

Next is an unresolved trichotomy involving Hechtioideae from Central America, Tillandsioideae, and the remaining bromeliads in subfamilies Navioideae, Pitcairnioideae, Puyoideae, and Bromelioideae. Bromeliads arose as C3 terrestrial plants on moist infertile sites in the Guayana Shield roughly 70 Mya, spread centripetally in the New World, and reached tropical West Africa (Pitcairnia feliciana) via long-distance dispersal about 10 Mya. Modern lineages began to diverge from each other 19 Mya and invaded drier areas in Central and South America beginning 15 Mya, coincident with a major adaptive radiation involving the repeated evolution of epiphytism, CAM photosynthesis, impounding leaves, several features of leaf/trichome anatomy, and accelerated diversification at the generic level. This ‘‘bromeliad revolution’’ occurred after the uplift of the northern Andes and shift of the Amazon to its present course. Epiphytism may have accelerated speciation by increasing ability to colonize along the length of the Andes, while favoring the occupation of a cloud-forest landscape frequently dissected by drier valleys.

  • Nuclear Genes, Matk and the Phylogeny of the Poales
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2018 Nuclear genes, matK and the phylogeny of the Poales Hochbach, Anne ; Linder, H Peter ; Röser, Martin Abstract: Phylogenetic relationships within the monocot order Poales have been well studied, but sev- eral unrelated questions remain. These include the relationships among the basal families in the order, family delimitations within the restiid clade, and the search for nuclear single-copy gene loci to test the relationships based on chloroplast loci. To this end two nuclear loci (PhyB, Topo6) were explored both at the ordinal level, and within the Bromeliaceae and the restiid clade. First, a plastid reference tree was inferred based on matK, using 140 taxa covering all APG IV families of Poales, and analyzed using parsimony, maximum likelihood and Bayesian methods. The trees inferred from matK closely approach the published phylogeny based on whole-plastome sequencing. Of the two nuclear loci, Topo6 supported a congruent, but much less resolved phylogeny. By contrast, PhyB indicated different phylo- genetic relationships, with, inter alia, Mayacaceae and Typhaceae sister to Poaceae, and Flagellariaceae in a basally branching position within the Poales. Within the restiid clade the differences between the three markers appear less serious. The Anarthria clade is first diverging in all analyses, followed by Restionoideae, Sporadanthoideae, Centrolepidoideae and Leptocarpoideae in the matK and Topo6 data, but in the PhyB data Centrolepidoideae diverges next, followed by a paraphyletic Restionoideae with a clade consisting of the monophyletic Sporadanthoideae and Leptocarpoideae nested within them. The Bromeliaceae phylogeny obtained from Topo6 is insufficiently sampled to make reliable statements, but indicates a good starting point for further investigations.
