Floristic explorations in different parts of Andhra
Pradesh from 2016 to 2017, yielded a few grass specimens from the Horsley Hills
of Chittoor District, Paderu cultivated fields and
the Lambasingi Ghat of
Visakhapatnam District. After careful
examination and identification with obtainable literature (Fischer 1928; Bor 1960; Kabeer & Nair 2009) these have been
identified as Bothriochloa insculpta, Cyrtococcum
patens var. patens, and Sacciolepis
myosuroides.
Bothriochloa Kuntze
comprising 35 species are distributed in Africa, Australasia, Europe, North
& South America, Pacific, temperate & tropical Asia (Clayton et al.
2006), and represented by 17 species in India (Kabeer & Nair 2009), of
which four are recorded in Andhra Pradesh (Pullaiah
2018). Cyrtococcum
Stapf, comprising 15 species are distributed in
Africa, Australasia, North & South America, Pacific, temperate &
tropical Asia (Clayton et al. 2006) and represented by six species in India (Moulik 2007; Kabeer & Nair 2009) of which five are
known to be distributed in Andhra Pradesh.
Sacciolepis Nash comprising
about 25 species are distributed in Africa, Australasia, North & South
America, Pacific, temperate & tropical Asia (Clayton et al. 2006) and
represented by four species in India (Karthikeyan et al.1989; Moulik 1997; Kabeer & Nair 2009), of which two are
recorded from Andhra Pradesh.
A perusal of the literature pertaining to Andhra
Pradesh State (Fischer 1928; Moulik 1997; Kabeer
& Nair 2009; Pullaiah 2018) revealed that these
three grass taxa have not been reported till date and the present collections
form new distribution records for the state.
Descriptions, illustrations, important notes and other details are
provided for the three taxa.

Stigmas 2, plumose. Caryopsis not
seen.
Habitat & Ecology: Found under the shades of trees
in moist deciduous forests.
Flowering & fruiting: July–May
Distribution: India (Andaman, Andhra Pradesh, Assam,
Bihar, Karnataka, Kerala, Maharashtra, Manipur, Meghalaya, Odisha, Sikkim,
Tamil Nadu, Tripura, Uttar Pradesh, and West Bengal); Sri Lanka, southeastern Asia.
Note: There are two forms in Cyrtococcum patens (L.) A. Camus var. patens:
one has spikelets with glabrous
nature and the other with verrucose.
There is regular confusion while treating var. latifolium
and var. patens as both have longer pedicels; var. latifolium
pedicels, however, are very long and capillary; while in var. patens they
are relatively shorter, but always longer than the length of spikelets. Bor (1960) treated spikelets with
verrucose as a separate species, i.e., C. muricatum
(Retz.) Bor,
but now it has been made a synonym to the var. patens. In our present collections only one specimen
has glabrous spikelets and
remaining are with tuberculate or verrucose spikelets. Since C. muricatum
has been reduced as a synonym to var. patens, the identification became
much confused and also resolves the confusion in the occurrence of the taxon in
Andhra Pradesh.

Notes
1. Sacciolepis myosuroides is often confused and also erroneously
identified as S. indica. Many characters are
intermediate between S. indica and S. myosuroides, but can be easily identifiable by its
smaller (c. 1.5mm), glabrous spikelets.
2. The
species recorded was from Warangal and Medak districts in Telangana region of
erstwhile Andhra Pradesh. All the
publications prior to 2014 (Kabeer & Nair 2009; Mani 2011) mentioned its
distribution as Andhra Pradesh. Since
there are no records for the species from present day Andhra Pradesh state till
date, the present collection forms a new distribution record for the same.
