nate, usually solitary, blue purple rose or yellow. Sepals narrow. Corolla- 

 tuhe short or long, fnnnel-sliaped ventricose or narrow ; lobes 5, snbequal, 

 imbricate in bud. Stamens 4, all perfect, didynamous, subequal ; anthers 

 oblong, cells parallel, approximate, base minutely spurred or submuticous, 

 the points only obscurely whitened. Ovary 4-ovulate, very hairy ; stigma 

 minutely bifid or subcapitate. Capsule elliptic, 4-seeded, base contracted 

 solid. Seeds compressed, orbicular or irregularly angular, rugose or tuber- 

 cular, glabrous. — Species 15, Tropical Asiatic and S. African. 



The species having only 2 fertile stamens are transferred to Uranthemiim, and 

 those with large bracts to Lepidagathis. It might be better to sink Asystasia in 

 Erwnthemum, for many of the species have a long narrow corolla-tube as in Mranthe- 

 mum, and the character of the stamens appears of rather less value than in separat- 

 ing Memiadelphis from Sygrophila.

Stems 1 foot, dichotomous, slender, nearly glabrous. Leaves 2 by f in., base 

 cuneate or rhomboid, undulate, subcrenate, dotted with most minute hairs above, 

 glabrous beneath j nerves 5-6 pair ; petiole J in. Spikes 1-2 in., slender ; flowers 

 mostly opposite ; bracts scarcely ^ in. ; lowest pedicels subobsolete. Calyx J in. ; 

 segments linear-lanceolate, glabrous on the back. Corolla glabrous; tube hardly 

 ^2 in. diam. ; limb hardly ^ in. in expanse. Stamens 4, nearly equal. Style nearly 

 glabrous; stigma subcapitate. Capsule \ in., 4-seeded, minutely hairy. — This differs 

 from A. coromandeliana (and its allies) in the very slender corolla; the tube is 

 widened only near its apex, and is there scarcely ^ in. broad.
