( rassulaceae novae Austro-africanae a S. Schönland descriptae. 179 



long, upper gradually smaller. Inflorescence terminal, pedunculate, sub- 

 capitate, few-flowered. Peduncle slender, 5—5,5 cm long, provided with 

 3 — 4 pairs of depauperated leaves, Flowers shortly pedicellate, bracts 

 and bracteoles toothlike. Calyx-lobes ovate, obtuse, c. 2 mm long, 

 connected at the base, rounded on the back, yellowish white. Petals 

 nearly free, suberect, oblong, 6 mm long, creamy-white, with the barest 

 indication of a rounded "mucro" behind the apex. Stamens, slightly 

 smaller than the petals, filaments filiform, white, anthers blackish-brown, 

 ovate. Carpels nearly as long as the stamens, ovaries suboblong, almost 

 straight along the inner margin, style subulate, sharply defined, but only 

 1 mm long, stigma distinct, squamae very small, broader than long, deeply 

 emarginate above. 



Western or Central Karroo? Contributed by Mr. A. Kuhn, May 1903. 



This species is allied to Cr. Harveyi Britt. et Bak. fil. {Cr. alpestris 

 Harv. [non Thunb]). It is easily distinguished by its style, calyx-lobes, 

 length of peduncle.

 connate nearly half their length, lobes ovate, blunt, c. 0,5 mm long. 

 Petals broadly ovate, c. 2 mm long. Stamens and carpels about the 

 length of the petals. Filaments slender, anthers with broad connective.

Cr. Dielsii is allied to Cr. Promontorii Schönl. et Bak. fil., but ditfers 

 from it in size and several details of floral strueture.
