Commelina badamica (Commelinaceae), a new species from India

A new species, Commelina badamica from the sandstone plateaus of Badami, Karnataka, India is described and illustrated. C. badamica is similar to C. clavata and C. diffusa, but differs in indefinite habit; linear–narrowly lanceolate leaves; puberulous or velutinous to tomentose spathes; clawless petals; velutinous ovary; radiately tri-lobed stigma; one capsule per spathe and trapezoidal, ventrally truncate seeds

INORGANIC STATUS OF TUBERS OF HABENARIA LONGICORNICULATA J.GRAHAM

Habenaria longicorniculata J.Graham is distributed throughout Western Ghats of peninsular India and Srilanka. Tubers of this terrestrial orchid are used as folk remedy and also eaten by some local tribes. Hence an attempt is done to evaluate mineral composition of this orchid. Mineral analysis was done by following standard method of acid digestion. In present study fourteen minerals are analysed for their content in tubers. Phosphorus is present in higher amount as compare to other minerals while Magnesium is lowest In case of trace elements Ferrous is found to be higher and Molybdenum is found to be low in quantity. Present study reveals that tuber of this orchid are good source of minerals and they can be used in food preparation by proper processing, results proves that undoubtedly it's a folk medicine. Further study on this and other orchids needs to be carried out to know the full potential in regards of its medicinal valueKeywords: Habenaria, folk medicine, minerals, orchidaceae

A Revision of the Genus Cyanotis D. Don (Commelinaceae) in India

The genus Cyanotis D. Don in India is taxonomically revised. Thirteen taxa of Cyanotis have been recognized with their updated nomenclature. Detailed descriptions, illustrations and geographical distribution have been provided. Cyanotis glabrescens (C. fasciculata var. glabrescens) and C. axillaris var. cucullata (Cyanotis cucullata) are new combinations and status proposed, notes on the complex of C. arachnoidea, C. burmaniana and C. tuberosa have been given, while some taxa warranting typifications have been lectotypified

Additions to the family Commelinaceae in flora of India

Commelina imberbis Ehrenb. ex Hassk., an African species, and Murdannia crocea subsp. crocea (Griff.) Faden, a Southeast Asian species, have been reported for the first time from India with their typification, descriptions, illustrations, color photographs, and notes on allied species. Keywords: Commelina, India, Murdannia, New record, Typificatio

GC-MS analysis of phytochemical compounds in the crude methanolic extract of roots of Murdannia lanuginosa and M. simplex (Commelinaceae)

The aim of the present study is to investigate the methanolic extract of the roots of Murdannia lanuginosa and M. Simplex (Commelinaceae) for their phytochemical compounds using Gas Chromatography–Mass Spectrometry (GC-MS). The study reveals three compounds in M. lanuginosa and six compounds in M. simplex respectively. M. lanuginosa could be used for antimicrobial, anti-inflammatory and anti-proliferative activity due to the presence of secondary metabolites like 4H-Pyran-4- one, 2, 3-dihydro-3,5-dihydroxy-6-methyl (Retention time 8.659) in the methanolic extract. While M. simplex extracts may be used in the development of fungicidal agent due to the presence of Salicylaldehyde, Azine (Retention time 22.608) as a major compound which is known for its fungicidal activity. A further study in the present taxa and family Commelinaceae is warranted to determine active principle of the extract as well as to elucidate their exact mechanism of action in various disorders
