Stem elongate; angles scabrid or prickly. Leaves 2-4 by |-1| in., acuminate, 

 margins and nerves beneath prickly. Cymes terminal, panicled, spreading, leafy. 

 Corolla rotate ; lobes ovate-lanceolate, apieulate. Anthers linear-oblong. Fruit -

This differs markedly from 7?. tinctorum in its slender habit, shorter broader 

 more distinctly petioled leaves, which are also membranous and are usually obovate 

 with a rounded apieulate tip; the corolla, too, is more funnel-shaped. Griffith 

 observes that it occurs in hedges and fields, and that he did not see it cultivated, 

 whereas he marks R. tinctorum as cultivated. 



4. R. sikkimensis, Kurz in Journ. As. Soc. 1874, ii. 188; scandent, 

 scabrid, leaves sessile 4 in a whorl elliptic or ovate-lanceolate acute or acumi- 

 nate 3-5-nerved from the base. 



EASTERN HIMALAYA; from Sikkim, alt. 2-5000 ft., J. D. H., &c. ; and Bhotan, 

 Griffith, to the Mishmi mountains (Upper Assam). 



A stout climber, branches retrorsely scabrid. Leaves 3-6 by 1-2 in., sometimes 

 cordate, scabrid on both surfaces, sometimes pubescent beneath, base acute or 

 rounded ; nerves deeply impressed above. Cymes large, panicled ; branches short, 

 spreading, leafy. Corolla rotate, lobes subacute. Anthers globose. Fruit in., 

 smooth. The handsomest species of the genus. 



5. R. Edg-eworthii, Hook.f. ; scandent, pubescent all over, leaves short- 

 petioled 4 in a whorl lanceolate acuminate 3-5-nerved from the base. 



WESTERN HIMALAYA ; Kumaon, alt. 3-4000 ft., Edgeworth, Strachey $ Winter- 

 bottom, Madden. 



Branches hardly scabrid, 8-ribbed, clothed, as are all parts (but less so on the 

 leaves above), with white spreading pubescence. Leaves 2-3 by | ^ in., membra- 

 nous, margins hardly scabrid, nerves deeply impressed above. Cymes as in R. sikki- 

 mensis, but more slender, and the branches ascending. Corolla-lobes lanceolate, 

 acuminate. Anthers ellipsoid. Fruit glabrous.

 shining, leaves sessile 4-8 in a whorl very narrowly linear keeled nerveless. G.

Stem excessively branched, ribbed, branches with short internodes. Leaves 1-4 

 by Yg-^ in., young filiform, thin and brittle, flat above, midrib strong beneath, smooth 

 or sparingly scabrid. Cymes very small, often of only 3-5-flowers on a peduncle not 

 longer than the small floral leaves or (the $ ?) on a slender peduncle in. or less. 

 Flowers minute. Corolla-lobes ovate, acute. Anthers ellipsoid. Fruit in. diam. 

 when didymous, on a slender peduncle, solitary, globose or didymous, smooth.
