 April. J. M. Wood, No. 4317. 



This plant differs from G. rivularis W. & E. by its generally

 size of involucral scales, and in the much smaller size of the flower- 

 heads. Flowers yellow. 



Ursinia brevicaulis Wood & Evans. Suftruticose. Stems 1 

 or more, erect or ascending, short, unbranched, leafy from base to 

 apex, leaves crowded, pinnatipartite in upper portion, segments 

 about 6, opposite or alternate, linear, simple or occasionally bifid, 

 glabrous, punctate, acute at apex, petiole elongate, gradually dilated 

 towards base, semi-amplexicaul, glabrous. Peduncle 1 -headed, 

 elongate, thinly clothed with minute hairs. Involucral scales 

 glabrous, outer ones dark-edged, inner larger, amply membrane- 

 tipped, all obtuse. Palae a little constricted below apex, terminating 

 in a rounded membranous lobe. 



Stems ^-1 inch long. Leaves l-lf iiich long, petiole below 

 lowest segments, f-l^ inch long ; segments 2-3 lines long. Pe- 

 duncles 2i-5 lines long. [p. 11.] 



Habitat: Natal; summit of Mont aux Sources, 10-11,000 feet

 petiolate, lanceolate, acute, entire, margins reflexed, glabrous. 

 Peduncles axillary, solitary 3-1 -flowered by abortion, the 1-flowered 

 peduncles with a pair of bracts above the middle, the 3-flowered 

 peduncles with smaller bracts, the lateral flowers only having a 

 pair of bracteoles below the calyx, the central flower without 

 bracteoles. Bracts linear, equalling the pedicels, bracteoles smaller. 

 Calyx 8-costate, 4-toothed. Petals 4, ovate. Stamens 4, exserted. 

 Flowers pink. 



The plant 15-18 inches high. Leaves \ inch long, less than
