The typification and taxonomy of Cephalotaxus mannii C. griffithii are discussed. Based on the study their morphological characters, taxonomic literature specimens in different herbaria, we consider both taxa as separate species not synonyms each other or harringtonii. A key to all is also provided for easy identification. During study, it found that, name was erroneous lectotypified. errors rectified by selecting proper lectotype.
The genus Cycadophila Xu, Tang & Skelley (Coleoptera: Erotylidae: Pharaxonothinae) associated with Cycas L. (Cycadacaeae) in Asia is reviewed. Strobilophila, new subgenus, five species described: (Strobilophila) assamensis species, C. (S.) hiepi kwaiensis tansachai and yangi all Cycas. For the nominate subgenus eight are described, (Cycadophila) abyssa (C.) collina species,C. samara convexa cyclochasma eurynota papua torquata four generic combinations proposed: vittata (Arrow)...
Cycads are an ancient group of seed plants that evolved during the Permo-Carboniferous period, some 280 million years ago, and rose to abundance in Jurassic just as dinosaurs did animal world. The has survived mass extinctions though depleted numbers with only 10 genera, about 350 species known occur scattered populations tropics subtropics According a report Cycad Specialist Group (SSC/IUCN) 53% cycad taxa facing threats fall into one categories IUCN Red List threatened (Donaldson 2003)....
An updated checklist of gymnosperms the western Himalaya situated within political boundaries in India is provided along with conservation status and distribution. Lectotype for three names viz., Cedrus deodara (Roxb. ex Lam.) G. Don, Pinus roxburghii Sarg., Picea smithiana (Wall.) Boiss. are designated.
Swertia jayantii (Gentianaceae), a new species from Jaintia hills, Meghalaya, India is described here with photographic illustration. The under subgenus Ophelia sect. due to the presence of single, naked nectary on each corolla lobe. It closely resembles S. cordata in having lobes blue-purple veins and quadrangular, narrowly winged stem. However, it can be distinguished by its deltoid-shaped nectary, calyx shorter than lobes, obtuse leaf base. A taxonomic description showing detailed...
Ex-situ conservation is an important key in the management of rare, endangered and threatened (RET) plant species its effectiveness depends on several factors. Maintenance viable germplasm subsequent propagation plays role long term many RET species. Nepenthes khasiana a rare gravely wild due to over-collection other threats. The needs urgent in-situ ex-situ conservation. Development easy propagate techniques would pave faster multiplication for use educational, medicinal horticultural...
Birches (Betula) are ecologically important plants in the Indian Himalayan Region, but they still not fully understood from taxonomic point of view. To provide a basis for research, we present synopsis Betula India and an account material on which names based. Lectotypes designated B. acuminata Lindl. (synonym alnoides Buch.-Ham. ex D. Don), cylindrostachya Wall. jacquemontii Spach.

A synopsis of the genus Erythrina (Fabaceae) in India is presented based on herbarium records, literature, and material available online. Lectotypes are designated for names E. arborescens Roxb., fusca Lour., indica Lam. (synonym variegata L.), resupinata Roxb. stricta a neotype lithosperma Blume ex Miq. Historical information typification name mysorensis Gamble given.
During the revision of Indian cycads, we attempted to consult type specimens endangered species, Cycas beddomei(1883: 85) and in process realized there has been a great deal confusion previous literature regarding syntypes this species. Here attempt resolve situation by identifying original material available Dyer designating an appropriate lectotype.
A checklist of the genus Gnetum (Gnetaceae) in India, based on data from herbarium records, literature and online databases, is presented. key to Indian species provided following seven names are lectotypified: G. contractum Markgr., gnemon var. brunonianum (Griff.) griffithii (Parl.) Markgr, latifolium Blume, funiculare macropodum (Kurz) oblongum Markgr.
A nomenclatural review of Abies delavayi and Picea brachytyla (Pinaceae) Nageia wallichiana (Podocarpaceae) is provided with their lectotypification.
Cycads are an ancient group of plants which have survived three mass extinctions. They dioecious, perennial, palm-like trees or shrubs with woody trunk above the ground subterranean. a relict seed that evolved in late Carboniferous early Permian around 300 million years ago. With ever-increasing interest cycad taxonomy over last two decades, number new species has increased significantly.
