Wight, t. 2086, a sarmentosa and C. dichrotricJia, Wight, t. 2087, 

 and C decumhens, Wight, t. 2088. The colour of the flowers 

 in Cyanotis varies from blue to purple on the same plant, and the 

 colour of the hairs on the filaments is eminently variable. 



4. Cyanotis nodiflora, Kunth, I. c. p. 136. 



Folia lineari-lanceolata. Racemuli scorpioidei, ad nodes dense congesti. 



Semina rugoso-punctata. 

 Hab. in Assam; in colhbus Khasiya, ad 500-4000 ped. alt. 



This plant has been issued from Kew as Cyanotic, sp. 17, and 

 is no, 58 ex Herb. Hook, f & Th. It has aliso frequently been 

 collected in Assam. It agrees closely with a specimen of C. no- 



dM 



It varies considerably in hairiness. 



Finallv, I still doubt whether it should not be made, with C. 

 iarbata, a variety of Cfasciculata. 



Steeptoliuiok, Edgew. 

 Volubile. Stamina 6 perfecta. Faniculce quasi terminales, ad 

 baain cordato-ovatis bracteis suffultse. Capsula trilocularis. 



Semina 6.

Folia longe petiolata, cordato-ovata, acuminata. Bractese ad basin i)e-

growing in quantity. I found nearly 75 per cent, of these cap- 



constructed 



ranged in all respects exactly as in the Sect. I. a of Commelyna, 

 in this paper, almost the only difference being that the capsule, 

 though irregular, was 3-valved. About 4 per cent, of the cap- 

 sules were 6-seeded ; and the remainder were 4-seeded and 3- 

 seeded. But there was hardly a case of an aborted ovule in the 

 whole 200 capsules. When the number of seeds was four, there 

 were two loculi with one large seed in each, and one loculus with 

 two superimposed small seeds in it, the small seeds differing from 

 the large in shape and in the position of the embryo, exactly as
