Abstract

This paper gives an account of the monocotyledonous plants growing in Manipur. In all 426 species (+ 8 varieties) representing 219 genera and distributed over 33 families have been dealt with. Hutchinson's system has been followed in arranging the families. Efforts have been made to find out the correct names m accordance with the latest International code of Botanical nomenclature. Only relevant and commonly used synonyms have been cited wherever required, immediately below the valid names. Citation of the original publication of the valid name has been made excepting several cases where the original paper concerned was not available to the author, for scrutiny.

A short description indicating the characteristic of the species has been given. A short ecological note has been added. In citation of the herbarium specimens, preference has been given to the author's personal collection. Others collections have not been cited completely. Species recorded by earlier workers from Manipur, but not examined by the author have also been cited in this paper.

Abstract

The paper records for the first time the occurrence of Psidium guineense Sw. in India from Tripura. It further records, probably for the first time, the transition from stamens to petals in the family Myrtaceae. This plant is exotic in and about Agartala, Tripura. It does not seem to be spreading. How and when the Immigrant entered Tripura could not be traced. The paper contains a detailed description of the species and the distinguishing characters by which it differs from Psidium guajava Linn.

Abstract

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.

Abstract

Molineria prainiana Deb spec. nov. (Family : Hypoxidaceae) is described with illustrations. The specimen was originally collected by I. H. 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. Biswas (1940) under the name Curculigo grandis Baker is also included in the description.

Abstract

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.

Abstract

The Indian Botanic Garden, Howrah, was flooded in October, 1978. Major part of the garden remained submerged for 3 days from 4th to 6th October, the water level rising up to 1.5 m in places. Some areas remained submerged under water for about a week. The damage caused to the garden is estimated and reported here.

Abstract

The present study on the taxonomic revision of Ophiorrhiza L. (Rubiaceae) in Indian subcontinent was carried out on the basis of specimens extant in the Indian Herbaria and some received on loan from several foreign herbaria. 47 species and 9 extra typical varieties are described with original citations, synonymy, typification, distribution, phenology and ecology. 4 species and 1 variety proposed as new have been described earlier. 4 varietal combinations havz been made and published. One newly described species is reduced here to the status of a variety. For identification of ttlxa two sections and a dichotomous key are given.

Abstract

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.

Abstract

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.
