Montia parvifolia (Moc. ex DC.) Greene var. batholithica Ertter & C.A.M. Prent. (Montiaceae) is described as a new variety from high elevations (2100–2800 m) in central Idaho and adjacent Montana, based on an overview of variation within the species using a combination of standard taxonomic analysis of herbarium specimens, morphometric analysis, fieldwork, and common garden studies. Taxonomic history of the species is summarized, morphology and life history are clarified, and variation elsewhere in the species is also briefly addressed.

A New Species

Several Ceratozamia populations from the “Carso Huasteco” region in Mexico have a controversial circumscription and have been historically identified as Ceratozamia fuscoviridis. In this paper, we present a review of the taxonomic history of this species and provide taxa circumscriptions based on analyses of herbarium specimens from this region and supplemented with fieldwork. For this, we have studied qualitative and quantitative morphological variation at population level. We recognize two species in this group: C. fuscoviridis and a new species, C. chamberlainii. Here, we provide two lines of qualitative and quantitative morphological evidence showing that plants of C. chamberlainii from southern San Luis Potosí to northern Hidalgo are distinct from C. fuscoviridis of central Hidalgo east of Veracruz. These species can be identified by leaflet form, leaf emergence color, color of the ovulate strobilus, and form of the megasporophyll, along with a combination of quantitative morphological characters.

The present paper is the third of a series of studies on the coccidia of Indian birds, and contains the description of six new species of these parasites, four of which belong to the genus Isospora, and one each to the genera Dorisiella and Eimeria, All the parasites described here belong to the Order Coccidiida, Family Eimeriidae. New avian hosts for some already known species are recorded here. The life-history of Eimeria barbeta Kar (1944) is described in detail. We also add here an amended description of Isospora ginginiana Chakravarty and Kar (1944 b), and a new variety of the latter.The majority of the birds were purchased from local dealers, while some were collected from Gaya, Bihar. Of twenty-eight different species of birds examined, eighteen were parasitized. The table at the end of this paper will indicate the number of birds parasitized (21) out of the total number examined (48), together with the locality of the hosts. Some of the birds were also infected with other protozoan parasites (haemosporidians and flagellates), descriptions of which are being published elsewhere.The methods adopted here are the same as previously employed by the authors (Chakravarty and Kar, 1944 a and b).Two species of birds, viz. the large Indian paroquet Psittacula eupatria nipalensis (Hodgs.) and the red-whiskered or Chinese bulbul Elathea jocosa emeria (Linn.), harboured a new Isospora, which does not resemble any known species of this genus. It is therefore proposed to call it Isospora psittaculae n. sp. after one of its hosts.

Dissochaeta is a plant genus of woody climbers, classified in the tribe Dissochaeteae (Melastomataceae). The taxonomic history of the genus is complicated and includes some allied genera like Dalenia, Diplectria, Macrolenes and Omphalopus. Most of them are already regarded as synonyms of Dissochaeta except for Macrolenes which is considered a separate genus here as well. Dissochaeta is characterised by its scrambling habit, interpetiolar outgrowths, 4-merous flowers, dimorphic stamens and berry-like fruits. A taxonomic revision of Dissochaeta is presented, which includes references, a complete list of synonyms, detailed morphological descriptions of the species and an identification key, as well as information on the distribution, habitat and ecology, vernacular names, notes and lists of examined specimens. Fifty four species and two varieties of Dissochaeta are recognised. We designate several lectotypes, propose eleven new combinations and we describe one new species and one new variety.

In 1985, the writer in collaboration with Prof. M. B. Mirza described Strongyloides from John's Sand-boa (Eryx johnii) in Aligarh and assigned it to S. stercoralis, creating for its reception a new variety, S. stercoralis var. eryxi.During July and August, 1950, while examining certain snakes at Hyderabad for helminth parasites, the writer found that Strongyloides infection was very common in the Rat-snake. Ptyas (Zamenis) mucosus, for almost all the snakes examined were found infected. In light infections not more than a few, ten to fifteen worms, were obtained from a single host, but as many as 100 to 125 specimens were collected from heavily parasitized snakes. It was also observed that though they may be found throughout the length of the oesophagus and the intestine, the seat of heaviest infection is the duodenum of the host.It seemed rather strange that one and the same species should parasitize a reptile as well as a mammal so a detailed study of the worm, both in its parasitic and free-living generations, was undertaken with a view to determining definitely whether, as previously believed, it is identical with the human worm Strongyloides stercoralis. As a result of this study the writer has come to the conclusion that the species infesting certain snakes in India is not identical with the human worm, S. stercoralis or any other species of the genus hitherto described.

ABSTRACT: This paper discusses some correspondence between Robert Schomburgk (1804–1865) and Adolphe Brongniart (1801–1876). Four letters survive, containing information about the history of Schomburgk's collection of fishes and plants from British Guiana, and his herbarium specimens from Dominican Republic and southeast Asia. A study of these letters has enabled us to confirm that Schomburgk supplied the collection of fishes from Guiana now in the Laboratoire d'Ichtyologie, Muséum National d'Histoire Naturelle, Paris. The letters of the German naturalist are an interesting source of information concerning the practice of sale and exchange of natural history collections in the nineteenth century in return for honours.
