268 ARNOl'T ON SOUTH AFRICAN PLANTS. 



p. 442; this genus is entirely omitted by Mr Harvey; it 

 belongs however to the Poriulacecs, where it is arranged by 

 Fenzel and Endlicher. 1 have strong reasons for thinking 

 this is the Herniaria lenticulata oiThunhGvg (not of Linnseus, 

 which according to Vahl and Smith, is Cressa creiica.). It 

 is also No. 26 of Sieber's Flora Mixta. 



The above observations relate to Drege's distribution at 

 the end of 1838, and beginning of 1839. There are how- 

 ever some other Cape genera on which I have made a few 

 notes, which I shall here add. 



Cycloptychis, E. M This genus of Cruci/erc^, has the 



petals as in Brachycarpeee ; the silicule (but not nearly 

 mature in my specimen), is orbicular-ovate, acuminated with 

 the persistent elongated conical style, somewhat compres- 

 sed and nucamentaceous. I suspect it is quite indehis- 

 cent ; the valves are furnished with a keel along their middle, 

 which is more prominent in the middle and provided with 

 several elevated wrinkles radiating from that point. The 

 septum is somewhat bony and orbicular. Ovules solitary in 

 each cell. Embryo (which I have only seen in the advanced 

 ovary with unripe seeds), has linear accumbent cotyledons, 

 not at all spiral, but rather bent back towards their apex. It 

 may perhaps be placed among the Spirolohece^ nucamentacese 

 latiseptae, but I prefer making a small group for it, in which 

 case, silicula nucamentacea latisepta cotyledonibus linearibus 

 will suffice both for a sectional and freneric character. 



Cavanilla, Th., or 3Iuldenhauera, Spr The species 



before me is No. 680 of Zeyher's Uitenhage collections, and 

 was found in the forests of Krakakamma; it is obviously 

 likewise that mentioned by Mr Harvey in the note at p. HO 

 of his Genera, and appears as he says to differ from the ori- 

 ginal species (C. scandens, Th., or M.scandens, Spr.), by the 

 acute instead of obtuse leaves. I have not seen the male 

 flowers, but the following analysis of the female may not be 

 unacceptable.
