1 iii. Peduncles -1 in. Sepals \ in., narrowly lanceolate, patently hispid like the 

 leaves. Flowers and berries as of R. ellipticum, but a little larger. 



4. XI. latifolium, H. f. Sf T.;' Clarke Comm. Sf Cyrt. Seng. t. 94; 

 leaves oblanceolate or obovate acuminate at both, ends subdenticulate mature 

 glabrous above more or less tawny and silkily woolly beneath, cyme 4-6 in. 

 cliam. very divaricate compound silkily woolly. Chelone latifolia, Ham. in

ASSAM, Wallich, Griffith; Mishmee Hills, Griffith. DISTEIB. Ava. 



Stem thick, silkily woolly upwards. Leaves opposite, 8 by 3 in. (sometimes 

 obovate larger) ; petiole 1 in. Peduncles 2 in,, stout; cyme umbellately decompound, 

 many- (sometimes 150-) fld. Sepals in., narrowly lanceolate. Corolla hardly 

 longer than the calyx, white with the upper lip purple (Griffith). Berry % in. cliam. 

 when dry. 



5. R. alternifolium. Clarke ; leaves (except the uppermost pair) 

 alternate elongate elliptic acuminate at both ends denticulate mature nearly 

 glabrous except the nerves, cymes peduncled compound tawny silky. 

 Corisanthera sp., Griff, ms. 



UPPER ASSAM ; Brahmakoond, Griffith. 



Stem upwards (with the innovations) cinnarnoneous, silkily woolly. Leaves of the 

 uppermost pair one 7 by 2| in., the other 2| by f in. ; petiole 1| in. Peduncles 

 1 in. ; inflorescence much as of R. latifolium, but less divaricate. Corolla distinctly 

 2-lipped, upper lip longer less deeply divided. Anthers largeish, dehiscent on the 

 inner face, minutely glandular at the apex, slits early confluent at the apex. Style 

 very long. This species (with some other Malay plants) entirely annuls the simple 

 distinction given in the Gen. Plant, between Rhynchotechum and Isanthera of " loaves 

 opposite " and " leaves alternate ;" except for the alternate leaves and peduncles it 

 is altogether a Rhynchotechum. 



6. B.. calycinum, Clarke ; glabrate in fruit, leaves elongate-elliptic 

 nearly entire, cymes short- peduncled very dense, sepals lanceolate pro- 

 minent. 



UPPBB ASSAM ? ; on the Soondra bank." 



Stem very thick. Leaves all opposite, 10 by 3| in., narrowed at both ends, sub- 

 coriaceous, not seen young ; petiole 2 in. Peduncles 1 in., 2-5-clustered ; cymes in 

 fruit subcapitate, very many-fld., glabrate ; bracts i in., oblong. Sepals iin. Corolla 

 not seen. Berry small, glabrous. 



XXY. CYRTAND1TA, Forst. 



Shrubs or trees. Leaves opposite, equal or unequal, or one of each pair 

 rudimentary or wanting. Flowers in cymes or heads, peduncled or sessile, 

 axillary ; bracts often large or connate into an involucre. Calyx free, ovoid 

 or tubular, diciduous or persistent ; teeth 5, acute. Corolla tubular- 

 funnel-shaped ; lobes 5, round, spreading, subequal (in the Indian species). 

 Stamens 2 perfect, 2 or 3 rudimentary; anthers included (in the 

 Indian species) 2-celled ; cells broad-oblong, subparallel, slits longitudinal. 

 Disc annular, or (in non-Indian species) unilateral subquadrate. Ovary 

 superior ; style long or short, stigma shortly 2-lobed ; placentae nearly 

 meeting, then revolute. Berry fleshy, ovoid oblong or linear, usually 

 white. Seeds very many, minute, ellipsoid, smooth, testa obscurely reticu- 

 lated. Species 160, Malayan and Polynesian, from Penang to the Sandwich 

 Islands.
