During the routine exploration ofthe Algal flora of Tharkand tbe authors came across an interesting algal
association withthe roots of the insetivorous plant Drosera burmanni Vahl. (Field No. 60068, dated
28.02.2013 from Kelaghat Dam of Simdega Dist of Sbrkhand (N 22°35'2520-E84°3621.00) which was
‘growing underexposed most conditions. Thee species of miroalge vz. Ntrium digits (Bréb.ex Ralf)

‘were isoetd from the association. On perusal of iterate, it revealed tht, 0 such repor onal association
‘with insectivrous plants was reported; heceitisrepote ere asafisteport

MATERIALS AND METHODS

‘The collected materials are brought to the laboratory and specimens were preserved in herbarium sheets, 2s
vellas in 3% formalin solution along with op of plycerin. The specimens are depositein CAL. For the
‘dentifcation of algal species relevant Iiterature (West & West, 1904 1912; Wes a, 1923; Transeau, 1951;
Randhawa, 1959; Gupta & Singh, 2001; Gupta, 2005; Toppo & Suse, 2007; Gupta, 2012) have been
consulted. The ost plant wasidentfed in Central National Herbarium (CAL).

Forascrscopic preprtiona snl chip oftootportion of the samples of Drasere burmanniVablalong With
tne sol was taken and kept in disiled water overnight. After tat sample was gently squeezed andthe liquid was
studied under the Olympus CX 41 compound microscope and photographs were taken under Olympus C-7070

RESULTS AND DISCUSSION

Inasinilar type ofstudy Gupta and Singh 2001), reported 14 species of alge belonging tothe members
of Cyanophycese (9), Bacillariophyceae (4) and Chlorophyceae I) growing in the rhizoidal one of moss
communities. Toppo & Susecla (2007 reported 21 algal taxa in association with bryophytes viz. Cyathodim
Kunze ex Lehm. (8) Bryum Hed. (7) and Funaria Hed. (6). Blu gren algal components are common in
the shioids of all three bryophytes. Chroococcur and Oscillatoria are recorded in association with all
‘yonhytes.

‘The study revealed that Drasera burmanni Vahl support three species of green microalgae under 3 genera
and 3 families ofthe members of Chlorophyceae on is root system. Its also interesting o note that ll the
‘members belong to Conjugales. No blue green algal association has been encountered. Itappearstobethe part of

‘made by the authors, only once and it is hoped that further surveys will yield many more algal taxa from tis
