No systematic study of the forests of Manipur was ever attempted. The present paper is based on a study of Manipur forests for about five years. It attempts at an identification and classification of forest types. In classification the Clementsian system has been followed in general with the acceptance of Bor's views on nomenclature modified still further. Topographical features, hill ranges, river system, lakes and jheels of the territory have been described. Factors determining vegetation types-climate, geology, soil, biotic and physiographic factors have been discussed. Ten climatic units included in eight formations have been described and influences of climatic, edaphic and biotic factors on them have been discussed.- A New Species of Tacca Forst. from North East Frontier Agency, India

This plant was collected by the senior author on way to Wakka (about 6 KM away at about 2,100 malt.), Tirap Frontier Division, N.E.F.A., India, on 2-7-61. The new genus (monotypic) is named in honour of Rev. Dr. H. Santapau, Director, Botanical Survey of India, Calcutta, as a token of deep regard and gratitude. The general appearance of the plant particularly the habit and the leaf, indicates apparent similarity with Indian Belladonna namely Atropa acuminata Royle ex Lindley.

The present paper on 'Medicinal Plants of Tripura' attempts to assess the potentiality of Tripura State with respect to medicinal plants. Out of 129 species of plants recognised as official drugs in 'Indian Pharmacopoea' 61 species occur in Tripura, 26 in wild and 85 in cultivated condition as garden plants. Of 350 items of vegetable products used in Unani and Ayurvedic medicine other than those recognised in 'Indian Pharmacopoea', 132 spp. occur in the State. Again, of 2535 taxa named in Chopra's 'Glossary of Medicinal Plants', 628 species are found here, 403 being in wild and 225 in cultivated state as garden plants. Of the wild ones, 143 spp. are rare. Again, 349 of those 628 species are known more for economic importance other than medicinal.- Economic Plants of Tripura State Timber Yielding Plants Principal uses

This series is based on Botanical Survey of the State by the author since 1956 and study of enormous scientific literature on uses of plants. It is an attempt to assess the economic potential of the vegetable resources of the state. The useful plants are grouped from a utilitarian point of view. Timber yielding plants are treated in two papers. Plants which are used for construction of houses, bridges, ships, boats, carriages, wagons, trucks and buses, railway sleepers, electric transmission poles, carpentry and cabinet making etc., and are found in Tripura State are named in this paper.- Economic Plants of Tripura State-timber Yielding Plants, Miscellaneous Uses

This paper "Bibliographical Review on the Botanical studies in Tripura" presents most probably all the literature that refers to the plan life in Tripura. No work of any appreciable size was ever published on any aspect of plants in this territory. In absence of such a work the author had to go through the chronological narratives on the rulers of the land, historical accounts, administrative reports, and litirary publications on Tripura for materials on botanical aspects. Such a search resulted in finding out several interesting records of Tripura plants. All these isolated references, however trivial may be, have been referred to in this paper. The views expressed by the author in course of the review of references, are based on his constant field and herbarium study on the vegetation and flora of Tripura for five years. For this reason he could not agree with the views expressed by the casual observers on the vegetation of Tripura.Full Text

Burkill in 1912, from Janakmukh during Abor Expedition and named by D. Prain as Curculigo grandis Prain in MSS., followed by publication of the name only by I. H. Burkill in Rec. bot. Surv. India (11 : 386, 1925) without any description. Recently J. Mitra in his Flowering Plants of Eastern India (1 : 50, 1958) made the new combination Molineria grandis Mitra that stands illegitimate. The same specimen is now named after late D. Prain, and described here anew. A specimen collected by N. L. Bor and published by K.

The present revision of the genus Rubia L. (Rubiaceae) is based on the specimens located in Indian herbaria. The area under consideration covers India, Sikkim, Bhutan, Nepal, Burma, Pakistan and Afghanistan, the latter three being represented only partially. 13 taxa in 9 species 2 varieties and 2 forms are treated in detail. One species R. aitchisonii Deb et Malick and one form R. cordifolia L. var. cordifolia f. strigosa Deb et Malick are added to science, while the status of R. infundibularis Hemsl. & Lace is reduced to R. albicaulis Boiss. var. stenophylla Boiss. f. infundibularis (Hemsl. & Lace) Deb et Malick. Lectotypes of 5 taxa and neotype of one taxon are designated. A key to the species is presented. In the present study the species described are grouped in two sections distinguished by the pinnate and palmate venations of the leaf. The form of the leaf and presence or absence of petiole are considered as taxonomic characters in subdividing the sections.Full Text

The Calcutta Herbarium (CAL) was initiated by William Roxburgh in 1793 with his own specimens of the Coromandel-Coast. His studies drew attention of the world Scientists to tropical flora. Nathaniel Wallich involved the world authorities in determining the specimens accumulated in CAL and those stored in the India Museum, London. He was uncharitably blamed for destroying the herbarium. He wished the most complete set to be sent to Calcutta. But it was ultimately sent to Kew, know as K-W. Nine botanists who worked in India collaborated in writing out 80 families in Hooker's Flora of British India. Sir George King managed to get the garden transferred from the Imperial to the Provincial Government charge. Soon he was disillusioned. He managed some contingency funds from the Imperial Government in 1890 in the name of Botanical Survey of India. No post or office was created. Botanical Survey of India was reorganized in 1954. The topmost priority of working out the flora of India has never been given due attention. State and District Floras were given untimely priority. 50% of 220 Scientific personnel in B.S. I. if properly deployed could write the Flora of India in twelve years to be followed up with compilation therefrom of all the State and District Floras. The remaining 50% the scientific staff could be fruitfully utilized for other important branches of study like economic botany, ecology, cytotaxonomy etc., all aiming at the welfare of man.Full Text

Taxonomic revision of the genus PAVETTA(Rubiaceae) in Indian subcontinent results in recognition of 25 species and 8 extratypical varieties. 13 species and 6 varieties described earlier are reduced to synonyms, and 5 species reduced to varietal rank. Two new combinations (P. indica var. glabrescens (Kurz) Deb & Rout and P. minor (Hook.f.) Deb & Rout) have been published. Dichotomous keys have been prepared for identification of taxa of all levels. Critical notes on nomenclature, morphological characters etc. have been provided after description of species wherever necessary. Morphological characters have been studied thoroughly. Special attention has been given on characters like indumentum, colleters, domatia, bacterial leaf-galls, pollen, seed coat, corolla microcharacters etc. The anatomical characters (internode, node, petiole and leaf) of P. indica have been studied. Information available in literature on wood anatomy, chromosome numbers and pollen nuclear numbers have been incorporated.
Morphology of indumentum and bacterial leaf-galls have been studied in all taxa. Colleters have been studied in 28 taxa; domatia found in 13 taxa. Microcharacters of outer surface of corolla tube (8 taxa) and inner surface of corolla lobes (19 taxa) have been studied under SEM in magnification up to 3200. Pollen morphology have been studied both in LM (27 taxa) and SEM (16 taxa). Seed coat morphology has been studied in cross section under compound microscope (13 taxa) and surface under SEM (10 taxa).
Of the species studied, 16 are distributed in India extending to adjoining region, 3 in Myanmar, Bhutan and Bangladesh and 9 species in Sri Lanka. P. indica is most widely distributed, almost throughout the country and extends to its adjoining region ; P. bimahica is endemic to Myanmar; six species are endemic to Tamil Nadu (Nilgiri and hills), Kerala and Andhra Pradesh and one species is distributed in Andaman and Nicobar Islands.
