 compressed, orbicular, when wet the fine white hairs spring out abundantly on all 

 Bides; areoles 0. — Habit and fruit-spikes so exactly those of atypical Strotilanthes 

 that neither Nees nor T. Anderson appear to have tried the ovules ; they are always 

 6, and the capsule has 6 seeds on 6 retinacula.

A shrub ; branches glabrous. Leaves 8 by 3 in., minutely crcnnlate, tubercular, 

 scabrous, becoming nearly glabrous ; petiole J In. Meads terminal on the arms of 

 a panicle, dense, sparingly ciliate or glabrous ; bracts | in. ; bracteoles \ in. Sepals 

 nearly J in., linear. Corolla densely hairy within, ventricose portion about as 

 long as the cylindric Anthers connivent in pairs. Ovary with (at least) 6 ovules. 

 Capsule (fide Kurz) 8-seeded. — The inflorescence is Strobilanthes-hke, and it might 

 be more naturally placed in Strohilanthes ; but it is very distinct specifically from 

 S. scaber, Nees, by the 6-8 ovules, very much longer flower and bearded filaments. 

 — The 3 examples ticketed as from Ceylon have 6 ovules, and seem identical with 

 the Pegu plant. Nees" S. scaber was a purple-fid. species founded on Wight h. 1943, 

 on which type-sheet T, Anderson has written S. heteromallus, T. Anders., nov. sp.

Shrubs. Leaves 0Tat« or elliptic, acuminate, lower tapering into the 

 petiole, upper subsessile, subcordate, crenate, upper surface densely covered 

 by raphides. Flowers sessile, solitary or 2-3-nate in opposite axils ; clusters 

 Tunning into close or intermpted spites, or panicled ; bract ovate or lanceo- 

 late ; bracteoles 2, narrow, about as long as the calyx. Calyx subequally 

 5-fid, segments linear or lanceolate, imperfectly connate often for half their 

 length. Corolla tubular- ventricose, suddenly widened about the middle; • 

 limb oblique, lobes 5, subequal, twisted to the left in bud. Stamens 2 

 perfect, or 4 perfect the 2 posterior mnch the smaller, anterior usually 

 exserted ; anthers oblong, 2-celled, muticous. Ovary and style glabrous, or 

 at the apex of the ovary glandular. Disc small, annular. Stigma simple ; 

 ovules 3-4 in each cell. Capsule oblong-linear, seed-bearing nearly from 

 the base. Seeds 6^8, on stout hooked retinacula, compressed, discoid, 

 apparently glabrous ; when moistened the abundant white hairs of extreme 

 tenuity straighten out. — Species 5, all of the Deccan and Ceylon. 



1. S. diandrum, Wiyht Ic. t. 1502 (not of Nees); leaves rhomboid- 

 elliptic or ovate, spikes interrupted viscous-pubescent, bracts ovate shorter 

 than the calyx, flowering calyx divided more than half-way down teeth
