 Fruit unknown. Maingay observes that this resembles a Melodinus.

 in terminal paniculate cymes. Calyx small, 5-lobed, eglandular within. Corolla 

 salver-shaped, tube nearly cylindric ; lobes rounded, velvety, overlapping to the 

 left ; throat villous. Anthers above the middle of the tube, included, subsessile,. 

 cells rounded at the base, dehiscing almost throughout their length. Disc 0..

MARTABAK ; Wallich. 



Leaves 2-4 in., oblong-lanceolate, obtusely caudate, acuminate, base acute, very 

 shining above and dark olive brown when dry, pale beneath, margins waved, coria- 

 ceous ; nerves very numerous, close and horizontal ; petiole slender, ^-f in. Cymes* 

 glabrous, rounded, shortly peduncled, 1-2 in. diam. ; bracts minute; pedicels short. 

 Calyx campanulate, lobes rounded, ciliolate. Corolla-tube - in., four times longer 

 than the calyx, inflated below the top ; lobes short, white with velvety hairs. 



0. C A HISS A, Linn. 



Spinous, densely branched, usually erect shrubs. Leaves opposite, small,, 

 coriaceous. Flowers in terminal and axillary peduncled 3-chotomous cymes. 

 Calyx 5-partite, glandular within or not, segments acute. CoroUa-tube cylindric,. 

 throat naked, lobes overlapping to the right (in the Indian species). Stamens. 

 at the top of the tube, included ; anthers lanceolate, cells rounded at the base.. 

 Disc 0. Ovary 2-celled; style filiform, stigma fusiform or columnar, minutely 

 2-fid ; ovules 1-4 in each cell, rarely more. Berry ellipsoid or globose, 2- (or by 

 abortion 1-) celled. Seeds usually 2, peltately attached to the septum, albumen 

 fleshy; cotyledons ovate. DISTRIB. Species about 20, African, Asiatic and. 

 Australian. 



The Indian species of this genus are very difficult of definition, and are probably 

 reducible to one or two very variable plants. The tickets of Wallich's specimens in. 

 Herb. Linn. Soc. have been, I fear, much misplaced.
