In all Indian floras Necharnandra alternifolia, a common aquatic herb of Hydrocharitaceae, is described under the genus Lagarosiphon. Some authors use the name Lagarosiphon roxburghii; others place it under Lagorosiphon alternifolia. The correct name of this plant is Nechamandra alternifolia (Roxb.) Thw. This note presents complete synonymy, detailed description and distribution in India.Full Text

The Shevaroys are situated to the north-east of Salem town at a distance of 26 km., the main bill station being Yercaud. Two seasonal explorations were made in the year 1958 and in all a total number of 51 species of ferns representing 14 families and 35 genera were collected.
In Shevaroys, the evergreen moist type of forest is seen where the vegetation is undisturbed and it is interesting to note that all the important fern families are represented here like Ophioglossaceae, Marattiaceae, Osmundaceae, Schizaeaceae, Gleicheniaceae, Hymenophyllaceae, Cyatheaceae and Polypodiaceae (sensu lato). Among the rare and interesting ferns, mention may be made of: Anemia tomentosa (Sav.) Sw, Antrophyum plantagineum (Cav.) Kaulf., Athyrium macrocarpum Bedd., Botrychium daucifolium Wall., B. lanuginosum Wall., Cyrtomium falcatum Presl var. caryotideum Wall., Dryopteris cochleata C., Chr., Hymenophyllum exsertum Wall, Leptochilus decurrens Blume, Lindsaea heterophylla Dry., Lygodium scandens Sw., Niphobolus gardneri (Mett.) Kunze, Osmunda regalis L., Pteris cretica L., P. quadriaurita Retz., var. argentea Bedd., and Trichomanes proliferum Blame.
The classification of Copeland is followed and the salient taxonomic features of the ferns collected are mentioned in the enumeration. Out of the plants listed Pteridaceae is well represented, the next in order being Aspidiaceae and Polypodiaceae (sensu stricto). The collections include a number of species which are new distributions to Salem District.

The Cumbum Valley and Pachakumatchi Hills are situated to the south-west of Madurai Town and lie between 77°12' and 77°30' E and 9°30' and 9°50' N. Three seasonal explorations were conducted in the months of June 1959, October 1959 and April 1960. The Pteridophyte vegetation is rich in the Pachakumatchi Hills where the humidity is high and the altitude reaches 1600 m. A total number of 50 species representing 14 families and 35 genera were collected and enumerated. The classification of Copeland is followed. Out of the plants listed, Pteridaceae is well represented, and next in order being Aspidiaceae and Polypodiaceae (sensu stricto).Full Text

Some of the salient features pertaining to the taxonomy of a few interesting aquatic angiosperms and their distribution, variability of fruits and seeds, their economic importance, floral biology, anatomy, embryology and cytology are presented here. The varied and diverse pattern of distribution of some Indian aquatic taxa is described with examples. Certain unique embryological features noticed in some aquatic plants are pointed out. Though the data on the cytplogy of Indian aquatic angiosperms is raher meagre, it is evident that from the evolutionary point of view, polyploidy has played an important role in the differentiation of races, varieties and species. The nomenclature of Nymphoides Hill and Necharmndra Planch., is discussed. Finally, the ample scope present for further work for a better understanding of these plants is emphasised.Full Text

The Bastar area comes under Bastar district of the Madhya Pradesh and lies south of Raipur between 19°0'-21°0'N and 81°0'-82°0'E. The major portion of this area has more or less remained botanically unexplored so far and three exploration trips were conducted in the years 1958, 1959 and 1961, and a total number of 481 species representing 336 genera and 112 families were collected.
The vegetation at the foot and lower slopes of the hills is of the mixed deciduous type. The undergrowth in these forests is rather sparse. Evergreen forests occur in Kanger Valley, Dharba, Kutumsar and along the upper slopes of Bailadila. The hill-tops, particularly at Dharba and Narayanpur, are rich in grasses and herbs and amidst these terrestrial orchids are also noticed. Since there are a number of tanks, at the foot of these hills and in the plains which are wet and marshy during the rainy season, interesting aquatic and marshy plants are met with.

The traps of Utricularia baoulaensis A. Chev., U. bifida L., U. graminifolia Vahl, U. kumaonesis Oliver, U. scandens Benj. and U. squamosa Wt. are studied.
The mouth of the trap has a distinct rim and is lateral, terminal or basal. The antennae or appendages on the dorsal side of the mouth are forked and not branched further in U. bifida, U. graminifolia, U. scandens and U. squamosa; in U. baouleensis they are further branched into two or three branchlets and in U. kumaonensis the appendages ramify further into uniseriate filaments bearing stalked, globose glands at their tips. The wall of the trap is 2-layered. There are bifid digestive glands along the inner layer of the wall in all the species, except U. kumaonensis where only quadrifid glands are seen. The mouth is guarded by a complicated trap mechanism, consisting of the door, velum and threshold.

During studies on the weed-flora of the Indian Botanic Garden, Sibpur, Howrah, two forms of "Dentella repens", were met with; they were identified as two distinct species-D. retens (Linn.) J. R. & G. Forst. and D. scrpyllifolia Wall. ex Airy-Shaw. Detailed descriptions and illustrations of both the species, hitherto not available in Indian floras, are given to facilitate easy identification. Specimens of Dentella present in various herbaria in India were studied in order to establish their correct identity.Full Text

Ten rare and imperfectly known species of Angiosperms collected from Agastyamalai Hills and surrounding regions in Tirunelveli District, Tamil Nadu, South India, are reported in this paper. Apama barberi Gamble, Discorea wightii Hk. f. and Piper barberi Gamble were rediscovered after a lapse of several years, and detailed/amended descriptions of them are appended. Eugenia mabaeoides Wt. forms a new record for India. Glycosmis macrocarpa Wt. and Piper trioicum Roxb, are re-established. Paragrewia poilanei Gagnep. ex Rao (Tiliaceae) is proved to be conspecific with Leptonychia moacurroides Bedd. (Sterculiaceae). Aeschynanthus planiculmis (Clarke) Gamble is synonymous to A. perrottetii A. DC. Sarcandra grandifoolia (Miq.) Subr. & Henry, comb. nov. and Tabernaemontana gamblei Subr. & Henry, nom. nw. are proposed.Full Text

Recent literature is reviewed and additional evidences presented to support Willis who had split podostemaceae into two families, Podostemaceae sensu stricto and Tristichaceae. In view of the available embryological and anatomical evidences it is suggested that further studies should precede attempts to trace the ancestry of these families to Crassulaceae or Saxifragaceae. Keys and distribution data for the genera of Tristichaceae and Indian Podostemaceae are given.Full Text

'Alpha' taxonomy practised in herbaria plays a very important role in botanical research even today as there is no sign of the exploratory phase of botany coming to an end in the near future. Herbaria could act as repositories of voucher specimens. The herbarium taxonomist should be allowed to devote at least some time to carry out revisions and monographic studies on difficult groups of plants even in those herbaria supported by public funds.Full Text

Studies on several populations of Nymphaea rubra in the Howrah, Hooghly and 24-Parganas districts in West Bengal and Barisal district in Bangladesh reveal that this species, claimed to be a native of Bengal, never sets fruit in nature. The plant propagates though stolons and vegetative buds and, in exceptional cases, by proliferation of flowers. The report of meiotic irregularity and high incidence of polysomaty and pollen sterility is indicative of its apomictic nature. The nomenclature of the plant has been discussed.Full Text
