"With the essential characters of Orthosiphon this species differs 

 from the rest of the genus in the very narrow foliage and in the union 

 of the two lower filaments, showing in the latter respect an approach 

 to the genus Syncolostemon. — G. Bentham."

Between Pietermaritzbure and the Crocodile River. 



Order AMARANTACE.E. 



52. ACHYRANTHES ASPERA, Linn. 



Matabele Land. 



A very robust form, with leaves more obtuse than usual ; still I do 

 not see any other difference. The same form has also been collected 

 in the Natal District. 



Order EUPHORBIACE.E. 



53. Euphorbia Oatesii, n. sp. 



A tiny little perennial, apparently branching from a thickened 

 rootstock, and about I5-2 inches high. Branches pubescent. Leaves 

 all alternate, subsessile, somewhat fleshy, and keeled ; the upper 

 ones lanceolate, acute ; lower ones elliptical, obtuse, 4-7 lines long ; 

 margin slightly thickened ; stipules minute, glanduliform. In- 

 volucre solitary, shortly peduncled, 4 lines in diameter, very short, 

 5-lobed ; lobes broadly rounded, villose, alternating with five subses- 

 sile glands, whose outer margin is very much larger than the inner 

 one, and apparently petaloid. Male flowers numerous, stamens with 

 very short filaments. Ovary very villose, styles spreading, shortly 

 bilobed at apex. 



Matabele Land. 



A very distinct little plant, belonging to Boissier's small section
