6. L. stricta, Benth. 



Erect or diffuse with 4-grooved and -angled stems clothed with 

 long and very short hairs, with very distant pairs of linear to elliptic 

 leaves -5 -1-5" and several leaves close to the inflorescence. Whorls 

 in a terminal and sometimes also one median head. Bracts many 

 long linear-filiform rigid, long-ciliate, 'S-V. Calyx "4* with the teeth 

 ■06-*2", longer than the villi at the mouth. 



Orissa, sand dunes near the coast, Setiff. PI. But this appears to be one of the 

 species inckided in Orissa from occurring in Ganjam (Madras Presidency). 



Leaves with long hairs both sides, 1)eneath also pubescent and glandular. The 

 two forms with narrow linear and shorter elliptic leaves are superficially very 

 different. Calyx shortly closely pubescent in flower, somewhat glabrescent. 



7. L. Clarkei, Hook. f. 



Very similar to the linear-leaved form of L. stricta, but calyx 

 shorter, -25", curved and closely densely pubescent, teeth •!" hispid, 

 mouth very densely villous. 



Parasnath, Clarke ! Fl. Nov. 



Leaves sometimes remotely toothed. Seeds oblong •!". 



8. L. nutans, Spreng. 



Very diffuse and not unlike the broader-leaved form of L. stricta. 

 Hairs long spreading and shorter deflexed. Leaves o-Vb" oblong or 

 narrowly-oblong, closely serrate or subserrate, obtuse, Avith long hairs 

 on the nerves beneath and short ones between. Petiole very short. 

 Whorls often 2-3 on a branch, terminal with a crown of leaves. 

 Bracts lanceolate, •25-*;3". Calyx hispid-hairy on the teeth, •3--4" 

 long, sharply curved about the middle, teeth subulate •05-*06".

9. L. cephalotes, Spreng. Andia durap arak', 8. 



An erect herb 1-2" 5 ft. high with 4-grooved patently hairy stems, 

 •elliptic-lanceolate (ovate or ovate-lanceolate, F.B.I.) remotely crenate- 

 serrate leaves l"5-2'5" long, and dense subglobose terminal (or sub- 

 terminal, being usually surmounted by a pair of leaves) whorls 1-2" 

 diam.. closely invested by a large rather membranous lanceolate or 

 elliptic and acuminate aristate bracts •5-*7"' long which are rigidly 

 ciliate and with a few stiff hairs on the back.

Leaves softly shortly pubescent and with longer hairs beneath and more evidently 

 punctulate than in many of the genus, sub-strigosely hairy above, sec. n. 3-5. 

 Petiole "l--^" long. Bracts strongly nerved. Calyx tubular 'G-'TS'' long, hairy
