Ledebouria hyacinthina var. hyderabadensis (M.V Ramana, Prasanna & Venu) S.R.Dutta, Chakral & H. Rodrigues var. et. stat. nov.

≡ Ledebouria hyderabadensis M.V Ramana, Prasanna & Venu (2012: 561) , basionym. ( Figure 6 .) Type:— INDIA. Telangana, Hyderabad, Damaiguda hills, 27 July 2009, P.V Prasanna & V.N Rao, 1459, (Holotype: CAL0000024579!; Isotype: BSID0002007!)

Distribution: — India, Telangana, Hyderabad, Damaiguda hill, Osmania university.

Habitat: —Growing on boulders where sandy soil is accumulated.

Phenology: —July to August.

Associates: — Cyperus meeboldii Kükenthal (1922:345) , Ophioglossum costatum Robert Brown (1810: 163) , Striga asiatica ( Linnaeus 1753:630) Kuntze (1891:466)

Specimens examined: — INDIA. Telangana, Hyderabad, Rajendranagar hill, 21 July 2016, P.T Giranje, 1412 (NGCPR00147!, NGCPR00148!), 15 June 2018, P.T Giranje, 1435 (NGCPR00149!, NGCPR00150!).Damaiguda hill, 10 July 2022, Suchandra et al, SHK31 ( RDNCP!).

Notes: — Ledebouria hyderabadensis was described on the basis of number of flowers (25 per inflorescence), shape of the leaf, absence of bulbil and blotches on the leaf. However, our phylogenetic & morphological work reveals that this taxon is nested within the Ledebouria hyacinthina clade along with other members of Ledebouria from India ( Figure 2 , 3 ). Beaked carpel a unique character only observed in this taxon can be used to relegate its status as a variety of L. hyacinthina .
