An erect, branched, herbaceous-green, parasitical herb, 1 to 2 ft. - 
high, not juicy; root tuberous, furnished with orange-cinnabar- 
coloured fibres; stem somewhat hispid, strictly erect, clothed 
below with small ovate sessile hispidulous or subglabrous green 
foliaceous scales and above with herbaceous green leaves; the 
latter opposite, subopposite, or alternate, more or less ovate and 
obtuse, paucidentate or nearly entire, narrowed and 3-nerved 
towards the shortly petiolate base, hispidulous, ranging up to 
1 in. long by nearly + in. broad; flowers in the upper axils 
solitary and gradually arranged in terminal spicate racemes ; 
peduncles or pedicels short, the lower ones about } in. long, the 
upper ones shorter; bracts 2, at the base of the calyx, linear- 
spathulate, $ in. long, shortly hispid ; calyx broadly campanulate, 
+ to + in., 5-cleft half-way down ; the segments ovate-triangular, 
but little acuminate, beset with white hairs, ciliolate; corolla not 
much exceeding the calyx, deep yellow, 5-lobed ; the tube dilated ;

inserted on the corolla-throat, alternating with its lobes, without 
any rudiment of a fifth stamen; filaments not bearded ; anthers

GoLtunco ALro.—Infesting crops of Arachis, too plentiful ; fi. and

This must be compared with IM. Vogelii (Benth.), but it is less 
scabrid, and the calyx-lobes are not so obtuse. It is the parasite 
mentioned as a new genus in Welw. Apontam. p. 551, sub no. 101.
