Brongniartia trifoliata. A spreading- bush 2-4 m. high, the 

 younger growth tomentose : leaves trifoliate, 6-10 cm. long, the 

 terminal leaflet sometimes twice as large as the others ; petioles 

 and petiolules white-tomentose ; leaflets coriaceous, glabrous, 

 oblong, cuneate or cordate at base, obtuse or retuse, 2-3 cm. 

 long, 1-2 cm. wide, somewhat repand ; petiolules 2-3 mm. long ; 

 stipules deciduous : pod 1-2 seeded, 3-3 >•> cm. long, 1V2-2 cm. 

 wide, glabrous, narrowly margined, tipped with an awn 3 mm. 

 long ; stipe 3 mm. long : flowers not seen. 



This bush is common at middle elevations of the Cape Region 

 Mountains. It seems to be a very distinct species, and in the 

 absence of flowers its generic position is indicated by the stipe 

 of the pod, and the strophiolate seeds having a very short, 

 straight radicle. The leaves resemble slightly those of B. incon- 

 stans but lack the stipules, are ochroleucous in color, thicker in 

 texture and veins not as prominent. From the characters, it 

 seems to be nearer B. Parryi than any other described species. 



Houstonia prostrata. A prostrate annual ; stems spreading 

 1-2 dm. long, hirtellous : leaves oblanceolate, 1 cm. long, hirsute, 

 especially the under side, margins revolute ; stipules scarious, 

 laciniate-dentate : flowers axillary near the ends of the branch- 

 lets on pedicels 1 mm. long or less : calyx i 1 - mm. long includ- 

 ing the ovary ; lobes more than half as long, acute : corolla light 

 purple, i)4 mm. long, lobes very short: capsule depressed- 

 globose, subdidymous, three fourths inferior : seeds oblong, cym-. 

 biform, the margins more or less involute, with a median hilar 

 ridge. 



This plant must be nearest //. parviflora. Growing flat upon 

 the clean sand of a dry stream it had the appearance of a pros- 

 trate Euphorbia. Collected near La Palma, in the Cape Region. 



Perezia pinetorum. Herbaceous, branching, 1 m. high, 

 puberulent, glandular above : branches spreading, leafy : the 

 inflorescence cymose-paniculate . leaves chartaceous, oblong, 

 acuminate, spinulose-dentate, the lower ones 2 dm. long, 1 dm. 

 wide, the large auricles nearly clasping the stem ; veins strongly 

 reticulated : heads on pedicles 2-3 cm. long, 15-20 flowered : 

 scales of the involucre linear-lanceolate, long-acuminate, the
