190 HOKN EXPEDITION — BOTANY. 



a few scattered white long hairs and the terminal fringe of dense short ones. 

 Capsule cylindrical, oval-oblong, half-inch by quarter-inch ; dissepiment fully half 

 as long ; seeds small, several lenticular, dark brown, minutely granulated, with a 

 narrow thick whitish margin. 



This species has the habit and the floral characters of G. heterochila, but its 

 viscid foliage approximates it to G. sepalosa, though it has not the leafy calyx-lobes 

 of that species. It differs from both by its cylindrical capsule, relatively long 

 dissepiment, lenticular (not flat) seeds and corolla-lobes not so much dissimilar. 



Elacholoma. F. v. M. and Tate. 



Calyx campanulate-ovate, its five lobes much shorter than the tube. Corolla 

 filiform -tubular, very much narrower than the calyx, widened only at the 

 summit; lobes minute, almost inperceptible. Stamens two, short-exserted; anthers 

 almost reniform, ex-appendiculate, dorsi-fixed, bursting anteriorly, their two cells 

 confluent. Style fully as long as the corolla, very thinly filiform. Stigmas two, 

 conspicuous, divergent, capillulary. Ovulary two-celled, without any parietal 

 intrusion beyond the dissepiment. Placentaries axillary, somewhat projecting. 

 Capsule turgidulous-oval, loculicidal-dehiscent. Seeds numerous, very minute ; 

 hilum basal ; albunient conspicuous ; embryo straight. 



A minute annual herb, whitish-grey from tomentellous vestiture ; leaves 

 linear, scattered or the lower opposite ; flowers sessile, axillary, solitary but 

 somewhat crowded at the summit of the stems. 



Elacholoma Houni, F. v. M. and Tate. 



An erect or diffuse herb, four inches or less high. Root rather copiously 

 fibrous. Leaves extremely narrow, hardly acute, slightly kelled, concave above, 

 flaccid, from one-third to two-thirds of an inch long. Calyces measuring about 

 one quarter of an inch in length, longitudinally five-streaked ; their lobes deltoid 

 semi-lanceolar, finally converging. Corolla glabrous, seemingly dark-coloured ; its 

 upper portion emerged. Stamens, ovulary and style glabrous. Stigmas subtle- 

 papillular. Capsule about one-sixth of an inch long ; the pericarp of almost 

 membranous texture, its dehiscence nearly bivalvular. Seeds brown, truncate, 

 ovate, almost smooth. Embryo nearly ellipsoid. 



This Scrophularinous genus recedes from all others of that order in the extra- 

 ordinary thinness and almost lobelessness of the corolla within an inflated calyx, 

 and dillers more particularly still in its cunq)ai itively long and quite capillulary 

 stigma divisions, by wliich sume ajjproacli of this genus tu the Susamete is indicated.
