Pleurocarpous mosses of Bangladesh: family - Sematophyllaceae

Abstract

A taxonomic account of eight species of pleurocarpous mosses from different localities of Bangladesh has been made. These are new addition to the pleurocarpous moss flora reported earlier. IntroductionIn previous reports (Khatun and Hadiuzzaman 1994, 1995, 2003, 2004a,b, 2005a,b, 2006a 42 species under 25 genera of pleurocarpous mosses were described. Recently, Banu-Fattah (2005) reported Distichophyllum schmidtii Broth., a species of pleurocarpous moss, which is rare in Bangladesh and was collected only by Sinclair (1955). In this paper altogether eight species under six genera of the family Sematophyllaceae under the order Hypnobryales have been reported. The species are Glossadelphus zollingeri, Taxithelium nepalense, Acanthorrhynchium papillatum, Trichosteleum boschii, T. stissophyllum, Aptychella delicata, A. borii, and Acroporium baviense. The present study reveals that among the above mentioned species Taxithelium nepalense is quite common and has been collected from 53 districts of Bangladesh, which is abundant in rainy season and mostly found on bark of trees. Tixier (1967) in his checklist mentioned only Taxithelium nepalense from the family Sematophyllaceae. Gangulee (1980) described all the above mentioned species in his "Mosses of Eastern India and adjacent regions" but he did not give any information on their occurrence in Bangladesh. He only mentioned about the species T. nepalense of Tixier's collections (from Chittagong, Bangladesh). In the present paper detailed taxonomic descriptions, illustrations and distributions along with keys to the genera and species and a short note on each taxon are provided. Except T. nepalense all the above mentioned species are new records for Bangladesh.

Four new records of Acrocarpous mosses for Bangladesh

“…Khatun and Hadiuzzaman (1994, 1995, 2003, 2005, 2006, 2007a published Pleurocarpous mosses of Bangladesh and some of them were collected from Boldha garden. Kamruzzaman (1995) gave an illustrated account of 45 species of Riccia L. which was later included by Hadiuzzaman (2007) in the Encyclopedia of Flora and Fauna of Bangladesh vol-5, three of which were collected from this garden.…”

Bryophyte flora of Greater Mymensingh District of Bangladesh - Class : Bryopsida

“…Banu-Fattah and Hadiuzzaman in a series of publications (1994, 1995, 1996a,b,c, 1998a,b,c, 2003a,b, 2004, 2006a,b) on the Acrocarpous mosses of Bangladesh described several species from the families Polytrichaceae, Ditrichaceae, Dicranaceae, Leucobryaceae, Calymperaceae, Fissidentaceae, Pottiaceae, Funariaceae, Splachnaceae, Bryaceae and Bartramiaceae from the studied region. Khatun (2002) reported many Pleurocarpous mosses from this region, but only those mosses are included here which have been published so far (Khatun and Hadiuzzaman 1994, 2003, 2005, 2006, 2007a. The specimens used by Banu (1991) and Khatun (2002) are preserved in the Bryology Herbarium, Department of Botany, University of Dhaka (DUBH).…”
