CROTALARIA ORIXENSIS VAR. NAIKII (FABACEAE): A NEW VARIETY FROM DECCAN
REGION OF INDIA.
Vijay A.Paithane, S. B. Sonje, and A.S. Bhuktar
ABSTRACT
A New variety of Crotalaria orixensis var. naikii belonging to Subsection
Calycinaehas been described, illustrated and compared with C.orixensis L.
along with artificial key.
Key Words: New variety, Crotalaria orixensis var. naikii, Fabaceae, Deccan
and Weastern ghat,
Introduction
The genus Crotalaria L. (Fabaceae) is
distributed in tropical and subtropical regions
of the world with c. 700 species (Polhill, 1982;
Mabberley, 2008; Abdull Jabbar et.al., 2010).
Crotalaria L. is the largest legume genus in
India having 93 species, 1 subspecies, 18
varieties and 2 forma (Ansari, 2008; Krishnaraj
et al. 2011; Daniel and Daniels, 2011; Sibichen
and Nampy, 2007). From Maharashtra,Cooke
(1967) reported occurrence of 32 species and
3 infra specific taxa for the Presidency of
Bombay. Almeida (1998) reported 43 species
and 5 infra-specific taxa for the state of
Maharashtra. Afterwards, Kothari (2000)
recorded 42 species and 3 infra-specific taxa
of flowering plants in Maharashtra.
Lakshminarasimhan (2002) added 7 species
and 2 infra-specific taxa to the Kothari's
contribution. Later on Paithane et al. (2012),
added Crotalaria clarkei Gamble to flora of
Maharashtra state. Consequently in flora of
Marathwada, Naik (1998) reported 21 species
of genus Crotalaria L. Thus in the flowering
plants of Maharashtra, the genus Crotalaria L.
accounts for 50 species and 5 infra-specific
taxa.
Material and Methods
In the Revisionary study of Genus
Crotalaria of Maharashtra, the authors have
collected specimens of Crotalaria L. from
various localities of Maharashtra
state.Specimens were brought to laboratory
and processed for herbarium specimens and
identified using pertinent literature (Almeida,
1998;Ansari, 2008; Kothari, 2000;Naik,1998
)and examination of the type
specimens.However, the critical study and
analysis of characters of the Section Calycinae
and Subsection Calycinae resulted in
discovery of new species allied to Crotalaria
orixensis L. which is described and illustrated
here. Short description, Phenology and
artificial key has been provide for the easy
identifications.
