Huitta.—Habit of Welampyrum ; flowers yellowish. In the wooded 
meadows of the Monino, sparingly and sporadic ; fl. beginning of April 
1860. No. 5801. An annual, erect, deep green, sub-parasitical herb ; 
stem tetragonal, rough ; leaves coarsely dentate, dilated at the base, 
rough ; flowers subsessile, axillary, solitary ; corolla yellow, galeate- 
bilabiate, red on the nerves, 5-cleft, the lobes obtuse; stamens 4, 
didynamous, included ; filaments naked; anthers 2-celled, attenuate

thickened, lingulate, recurved, bilobed at the apex, the lobes rather

Hymenospermum dentatwm Benth. in Wall. List, n. 3963 (1831).

indica Benth. in DC. Prodr. x. p. 339 (1846). A. dentata O.

Punco ANponGo.—An annual, erect herb; leaves membranous, 
curved ; flowers yellow. In moist places planted with manioc, near 
Calunga, at the sides of the river Miége; fl. and fr. April 1857. 
No. 5849. An annual, erect herb, simple below, alternately branched 
at the inflorescence, 13 ft. high; leaves subopposite. Perhaps the 
same species. No. 5894. 
This species has been united with JW. sessiliflorum by O. Kuntze, 
Rey. Gen. Pl. ili. 2, p. 237; he calls both Nigrina sessilifora. Our 
plants are doubtfully placed here and should be compared with the form 
subpetiolatum (O. Kuntze, l.c., p. 238), the type of which I have not seen. 
3. M. rigidum Hiern, sp. n. 
An erect, scabrid, apparently annual, somewhat wiry herb, 9 to 
12 in. high, branched from the base or simple; stem rigid, more 
or less hispidulous ; branches erect or ascending, rather slender 
and tough, more or less hispid with short whitish hairs; leaves 
opposite, linear-lanceolate or narrowly oval-oblong, obtuse at the 
apex, a little or scarcely narrowed at the sessile base, scabrid at
