nov. and L. udarii M. Dey et D. K. Singh sp. nov., are described from Darjeeling district of West Bengal and East district of Sikkim
respectively in Eastern Himalaya, India. While, the former is characterized by obovate leaf lobes with acute – subacute leaf apices
and entire margin; rectangular – trapezoid underleaves with rectangular – lanceolate lobes which are 3-4 cells long, 2-3 cells wide,
or rarely 1 cell wide at apex, and crenulate – denticulate margin; presence of ocelli in female bracts and bracteoles and obconical
perianth with truncate apices and 5 obliquely – horizontally spreading horn-like keels extending from apex to 1/2-3/5 of perianth
length, the latter is distinct in having small length-breadth ratio of the leaves ranging between 1.2:1-1.3:1; obovate leaf lobes with
subacute apices; terminal as well as intercalary androecia with male bracteoles present throughout; numerous ocelli scattered on
female bracts, bracteoles and perianth and obconical – campanulate perianth with 5 smooth, erect – obliquely spreading horn-like
keels. A key to the Indian species of the genus has been provided.
