A Numerical Taxonomy of the Genus Rosularia (Dc.) Stapf from Pakistan and Kashmir
Pak. J. Bot., 44(1): 349-354, 2012. A NUMERICAL TAXONOMY OF THE GENUS ROSULARIA (DC.) STAPF FROM PAKISTAN AND KASHMIR GHULAM RASOOL SARWAR* AND MUHAMMAD QAISER Centre for Plant Conservation, University of Karachi, Karachi-75270, Pakistan Federal Urdu University of Arts, Science and Technology, Gulshan-e-Iqbal, Karachi, Pakistan Abstract Numerical analysis of the taxa belonging to the genus Rosularia (DC.) Stapf was carried out to find out their phenetic relationship. Data from different disciplines viz. general, pollen and seed morphology, chemistry and distribution pattern were used. As a result of cluster analysis two distinct groups are formed. Out of which one group consists of R. sedoides (Decne.) H. Ohba and R. alpestris A. Boriss. while other group comprises R. adenotricha (Wall. ex Edgew.) Jansson ssp. adenotricha , R. adenotricha ssp. chitralica, G.R. Sarwar, R. rosulata (Edgew.) H. Ohba and R. viguieri (Raym.-Hamet ex Frod.) G.R. Sarwar. Distribution maps of all the taxa, along with key to the taxa are also presented. Introduction studied the genus Rosularia and indicated that the genus is polyphyletic. Mayuzumi & Ohba (2004) analyzed the Rosularia is a small genus composed of 28 species, relationships within the genus Rosularia. According to distributed in arid or semiarid regions ranging from N. different workers Rosularia is polyphyletic. Africa to C. Asia through E. Mediterranean (Mabberley, There are no reports on numerical studies of 2008). Some of the taxa of Rosularia are in general Crassulaceae except the genus Sedum from Pakistan cultivation and several have great appeal due to their (Sarwar & Qaiser, 2011). The primary aim of this study is extraordinarily regular rosettes on the leaf colouring in to analyze diagnostic value of morphological characters in various seasons. -
Mountain Laurel Or Rhododendron? Recreation Area Vol
U.S. Dept. of the Interior National Park Service . Spanning the Gap The newsletter of Delaware Water Gap National Mountain Laurel or Rhododendron? Recreation Area Vol. 7 No. 2 Summer 1984 These two members of the plant kingdom are often confused. Especially before they blossom, they resemble each other with their bushy appearance and long, dark-green leaves. Both plants ARE shrubs, and they are often seen growing together. Another thing they have in common: although some species have not been proven dangerous, it is well to consider ALL members of the laurel- (Above) Rhodendron. rhododendron-azalea group of plants as potentially toxic. The rhododendron (rhododenron maximum) is undoubtedly the most conspicuous understory plant in the mountain forests of Pennsylvania. In ravines and hollows and along shaded watercourses it often grows so luxuriantly as to form almost impenetrable tangles. In June or early July, large clusters of showy blossoms, ranging from white to light rosy- pink, appear at the ends of the branchlets. People travel many miles to witness the magnificent show which is provided by the rhododendron at flowering time. In the southern Appalachians the plant grows much larger than it ordinarily does in this area, often becoming a tree 25 feet or more in height. The dense thickets of rhododendron in the stream valleys and on the lower slopes of our mountains are favorite yarding grounds for deer when the Rhodendron. snows become deep in the wintertime. The dark- green, leathery leaves react to subfreezing temperatures by bending downward and rolling into a tight coil. Although the shrub is often browsed to excess, it has little or no nutritional value. -
Kalmia Procumbens (L.) Gift & Kron Synonym: Loiseleuria Procumbens (L.) Desv
Kalmia procumbens (L.) Gift & Kron synonym: Loiseleuria procumbens (L.) Desv. alpine azalea Ericaceae - heath family status: State Threatened, BLM sensitive, USFS sensitive rank: G5 / S1 General Description: Adapted from Douglas et al. (1998-2002): A diffusely branched, dwarf evergreen shrub, trailing on the ground without rooting at the nodes. Stems 5-30 cm long, hairless or minutely hairy. Leaves with partially clasping stalks, opposite; blades leathery, bright green, narrowly elliptic, 3-8 x 1-3 mm, hairless above, short hairs below, with revolute margins. Floral Characteristics: Flowers 2-6, light to deep pink, clustered in axils of upper stem leaves, erect on short stalks 1-10 mm long, straight or curved. Corolla bell-shaped, 5-lobed, 4-5 mm long. Calyx red, 1.5-2.5 mm long, hairless, persistent. Stamens 5, anthers unawned, opening full length by slits. Fruits: Ovoid capsules 3-5 x 2-3 mm. Identifiable July to August. Identification Tips: Phyllodoce species are closely related to Kalmia, but they have alternate, linear leaves 6-16 mm long, usually 10 stamens, and anthers that open by two terminal pores. Cassiope species have smaller leaves (less than 5 mm long) lacking revolute margins, awned anthers that open by terminal pores, and usually nodding flowers. K. procumbens differs from K. microphylla (two varieties occur in Washington) in having capsules with 2-3 chambers, smaller petals ( 3-5 mm vs. 7-9 mm) cleft half their length, and 5 stamens. K. © Margaret Williams microphylla has capsules with 5 chambers, petals that are only shallowly cleft, and 10 stamens. Range: Circumpolar. -

Stem-bark and leaves are used as remedies for malaria, stomachache, coughs and several skin diseases. Consequently, the plant is endangered because of uncontrolled harvest from the wild and lack of domestication. There is therefore fear of poor quality commercialized products due to lack of quality control mechanisms. The objective of this study was to investigate features of diagnostic value that could be used to confirm its authenticity and purity. Samples in the study were obtained from six different geographical locations in Kenya by random purposive sampling. Macroscopic and microscopic studies of the leaf and stem-bark were done based on a modified method from the American herbal pharmacopoeia. The study revealed over five macroscopic and organoleptic characteristics for W. -
Kalmia Latifolia Family: Ericaceae Mountain Laurel
Kalmia latifolia Family: Ericaceae Mountain Laurel The genus Kalmia contains about 7 species native to North America. Mountain Laurel is the only species that attains tree size, the other six are shrubs. The genus Kalmia was dedicated by Linnaeus to his student Peter Kalm (1716-1779), Swedish botanist who traveled and collected in Canada and eastern United States.

The Tree Mountain Laurel is a large shrub, occasionally reaching tree size (reaching 40 feet tall & 2 feet in diameter) in the eastern US. The leaves, buds, flowers and fruits are poisonous to humans and cattle, but not to indigenous wildlife such as deer. It has leathery, evergreen leaves and very showy flower clusters, making it a favorite plant for ornamental purposes. It prefers acid soils from lowlands to 4,000 feet elevations. It grows in association with oaks, tulip poplar, beech, sugar maple, white pine and sourwood. The Wood General The wood of Mountain Laurel is heavy, hard, strong but rather brittle, with a close, straight grain. It has a light yellow sapwood and a yellow brown heartwood, spotted with red.

Monograph No taxon left behind? – a critical taxonomic checklist of Carpinus and Ostrya (Coryloideae, Betulaceae) Norbert HOLSTEIN 1,* & Maximilian WEIGEND 2 1,2 Rheinische Friedrich-Wilhelms-Universität Bonn, Bonn, Nordrhein-Westfalen, Germany. * Corresponding author: [email protected] 2 Email: [email protected] Abstract. Hornbeams (Carpinus) and hop-hornbeams (Ostrya) are trees or large shrubs from the northern hemisphere. Currently, 43 species of Carpinus (58 taxa including subdivisions) and 8 species of Ostrya (9 taxa including sudivisions) are recognized. These are based on 175 (plus 16 Latin basionyms of cultivars) and 21 legitimate basionyms, respectively. We present an updated checklist with publication details and type information for all accepted names and the vast majority of synonyms of Carpinus and Ostrya, including the designation of 54 lectotypes and two neotypes. Cultivars are listed if validly described under the rules of the ICN. Furthermore, we consider Carpinus hwai Hu & W.C.Cheng to be a synonym of Carpinus fargesiana var. ovalifolia (H.J.P.Winkl.) Holstein & Weigend comb. nov. During the course of our work, we found 30 legitimate basionyms of non-cultivars that have been consistently overlooked since their original descriptions, when compared with the latest checklists and fl oristic treatments. As regional fl oras are highly important for taxonomic practice, we investigated the number of overlooked names and found that 78 basionyms were omitted at least once in the eight regional treatments surveyed. -
