Throughout India on the plains.— Distrib. Afghanistan. Persia. Australia. 



Glabrous, very erect, 6-24 in.; branches numerous, sharply quadrangular. Cauline 

 leaves 1-lA in. Bracteoles on the cyme-branches most minute, linear. Calyx cam- 

 panulate, hemispheric or scarcely elongate ; teeth 4, short- triangular. Petals 0, or 

 small and caducous. Stamens 4, 6 or 8. Capsule often ultimately red, globose, not 

 enclosed by the calyx. Seeds half-ellipsoid, excavated on the plane foce.^Very 

 closely allied to A. senegalensis and united with it by Mr. Hiern, perhaps correctly, 

 but the two forms do not meet or pass into each other in India. Cryptotheca dicho- 

 toma, Blume Bijd, 1128; DC Proar. iii. 76 (Aramannia microcarpa, DC Prodr. iii; 

 il), from Java and Timor, has been united with A. muliijlora Eoxb, hj Kurz t?i 

 Journ. As, Soc. 1871, pt. ii. 56, but differs in the much more elongate calyx-tube and 

 larger cauline leaves : it is certainly very near A, muliijlora.

 ^^etimes very narrow. Calyx in fruit \ in., often minutely pubescent or scabrid, 

 nearly truncate ; teeth 4, small. Petals ^^ in., obovate, rose-coloured. Stamens 8, 

 filaments long, dark-red. Capsule somewhat ellipsoid, as long as the calyx. Seeds 

 fiubhemispheric, — This species is reduced to A, latifolia Lhm. by Griseb. Fl. Brit. 

 ^ i^t Indies 27 ; but the West Indian specimens, though like the Indian in leaves 

 ^d habit, are entirely without the subalate angles of the ripe fruit which form the 

 .essential character of A. octayidra.
