Variation in Seed Production and Germination in 22 Rare and Threatened Western Australian Verticordia (Myrtaceae)
Journal of the Royal Society of Western Australia, 84:103-110, 2001 Variation in seed production and germination in 22 rare and threatened Western Australian Verticordia (Myrtaceae) A Cochrane1, K Brown2, S Cunneen3 & A Kelly4 1Threatened Flora Seed Centre, Department of Conservation and Land Management, Locked Bag 104, Bentley Delivery Centre, Perth WA 6983 2Environmental Weeds Action Network, 108 Adelaide Terrace, East Perth WA 6000 3CSIRO Centre for Mediterranean Agricultural Research, Floreat WA 6014 424 Carnarvon St, East Victoria Park WA 6100 email: [email protected] Manuscript received August 2000, accepted March 2001 Abstract This study investigates the reproductive potential of 22 rare and threatened Western Australian taxa in the genus Verticordia (Myrtaceae) over a 5-year period. Considerable inter- and intra-specific variation in both seed production and germinability was demonstrated for the majority of taxa. The seed to flower ratio, or “seed set”, ranged from 0% to 68% with an overall mean of 21% in 82 accessions representing seed from 48 populations of the 22 taxa. Percentage germination ranged from 7% to 100% with an average of 49% for 68 accessions. The precariously low annual reproductive capacity of some of the more restricted and critically endangered taxa threatens their survival and unexpected disturbance events may result in population decline or even localised extinction. Mitigation measures such as the reintroduction of plant material into new sites and the enhancement of existing populations through additional plantings may be warranted for many of Western Australia’s rare and threatened Verticordia. Keywords: Verticordia, seed production, germination Introduction prominently displayed feathery flowers are borne singly but appear as heads or spikes and are generally brightly Verticordia (family Myrtaceae, sub-family coloured, ranging from yellow to red to purple. -

Las Especies Del Género Alyogyne Alef. (Malvaceae, Malvoideae) Cultivadas En España
Las especies del género Alyogyne Alef. (Malvaceae, Malvoideae) cultivadas en España © 2008-2019 José Manuel Sánchez de Lorenzo-Cáceres www.arbolesornamentales.es El género Alyogyne Alef. comprende arbustos perennes, con indumento denso o de pelos esparcidos, con las hojas alternas, pecioladas, enteras, palmatilobadas o muy divididas, con estípulas diminutas y caedizas. Las flores son solitarias, axilares, sobre pedicelos largos y articulados. El epicáliz posee 4-10(-12) segmentos unidos en la base; el cáliz consta de 5 sépalos, más largos que el epicáliz, y la corola es más o menos acampanada, regular, formada por 5 pétalos obovados de color blan- co, rosa, lila o púrpura, adnatos a la base de la columna estaminal, cubiertos de pelos estrellados externamente. El androceo posee numerosos estambres (50-100) dispuestos en verticilos, con los filamentos unidos formando una columna que rodea al estilo, y las anteras uniloculares, dehiscentes por suturas longitudinales. El gineceo posee un ovario súpero, con 3-5 lóculos, cada uno de los cuales encierra 3-10 rudimentos seminales. Los estilos están unidos casi hasta el ápice, dividiéndose finalmente en 5 estigmas. El fruto es una cápsula dehis- cente por 3-5 valvas, conteniendo numerosas semillas (3-50) de pequeño tamaño, reniformes o globosas, glabras o pelosas. El nombre procede del griego alytos = unido y gyne = mujer, en alu- sión a los estilos unidos. Según Lewton (1915), el nombre debería ser Allogyne, del griego állos = otro, diferente y gyne = mujer, hembra, en alusión a la diferencia con Hibiscus en cuanto a los estilos. Realmente esta es la gran diferencia con el género Hibiscus, donde los estilos se separan por debajo de los estigmas, mientras que en Alyogyne están unidos justo hasta llegar a los estig- mas, momento en que se dividen. -

Thryptomene micrantha in flower Tasmania 1 Threatened Species Section – Department of Primary Industries, Parks, Water & Environment Listing Statement for Thryptomene micrantha (ribbed heathmyrtle) IDENTIFICATION & ECOLOGY Thryptomene micrantha is a small shrub in the Myrtaceae family (Curtis & Morris 1975), known in Tasmania from the central east where it grows in near-coastal heathy woodlands on granite-derived sands. Flowering may occur from mid winter through to early summer. Beardsell et al. (1993a & b) noted that Thryptomene species tend to shed their fruit each year within 6 to 18 weeks of flowering, with at least two years ageing and weathering required before a seed’s initial dormancy is broken. Dormancy was found to be due largely to the action of the seed coat acting as a barrier to water uptake, with the surrounding fruit having a smaller inhibitory effect. -

Bossiaea Ensata
Bossiaea ensata Family: Fabaceae subfamily Faboideae Distribution: Woodland and open forest in south-east Queensland, eastern New South Wales and north-east Victoria. Common Sword bossiaea. Name: Derivation of Bossiaea... After Boissieu de la Martinière, a physician Name: and plant collector who participated in the expedition of Jean-Francois de La Perouse in 1785. ensata... From Latin ensatus, sword-like, referring to the flattened stems of this species. Conservation Not considered to be at risk in the wild. Status: General Description: Bossiaea is a genus of about 50 species all of which occur naturally only in Australia. They are found in all States and are small to medium shrubs. Bossiaea ensata Photo: Brian Walters Bossiaea ensata is a small shrub, often with a low, spreading habit and only rarely reaching about 1 metre high. It is generally leafless and has flattened, winged stems whose function takes the place of leaves (the leaves are actually reduced to small scales along the flattened stems). The stems are usually 3 to 10 mm in width (which distinguishes B.ensata from the similar B.scolopendria, which has winged stems up to 15 mm wide). True leaves are sometimes seen near the base of the plant or on juvenile stems - these true leaves are small and oval shaped. The flowers are yellow with a red centre and have the typical "pea" shape consisting of 4 petals; the "standard", the "keel" and two "wings", as shown in the diagram. They occur in the leaf "scales" in late spring and summer and are about 10-15 mm long. -

A REVISION OF THE GENUS TEMPLETONIA R.Br. (PAPILIONACEAE) by J. H. Ross* ABSTRACT The endemic Australian genus Templetonia is revised. Eleven species are recognized and the uncertainty concerning the application of the name T. sulcata (Meissn.) Benth. is discussed. This discussion includes the selection ol a lectotype for Bossiaea rossii F. Muell., a possible synonym. Descriptions, a key to the identification of species, illustrations, and distribution maps are provided, together with notes on ecology and relationships. Two previous papers describing T. incana (.Muelleria 4: 247-249 (1980)) and T. negketa (loc. cit. 390-393 (1981)) should be used in conjunction with the present revision. INTRODUCTION Templetonia, a small genus of 1 1 species described by R. Brown in Ait. f Hort. , Kew. ed. 2, 4: 269 (1812), was named in honour of the Irish botanist John Templeton (1776-1825) ot Orange Grove, Belfast. -

Sida Rhombifolia
Sida rhombifolia Arrowleaf sida, Cuba jute Sida rhombifolia L. Family: Malvaceae Description: Small, perennial, erect shrub, to 5 ft, few hairs, stems tough. Leaves alternate, of variable shapes, rhomboid (diamond-shaped) to oblong, 2.4 inches long, margins serrate except entire toward the base. Flowers solitary at leaf axils, in clusters at end of branches, yel- low to yellowish orange, often red at the base of the petals, 0.33 inches diameter, flower stalk slender, to 1.5 inches long.
