South Africa ? Described from a plant received from Prof. 

 H. H. W. Pearson, of Cape Town, in 1905, which flowered in the 

 Succulent House at Kew in April, 1907. 



This plant is allied to II. translucent, Haw. (Aloe arachnoides, 

 var. translucens, Ker-Gawl. in Bot. Mag. 1. 1417), which has fewer 

 leaves with a different phyllotaxy, the outer ones spreading and 

 the margins beset with flattened deltoid teeth, not with setae. In 



S. Pearsoni fiwri th& nntarmnHt leaves curve upwards.

 Survey of Egypt. Another set from the same district, but collecwa 

 by Dr. John Ball, also of the Geological Survey of gm* , was <XH* 

 munieated quite recently by Prof. G. Schweinfurth in ord r that 

 it might be included in the present article the object f ! whici m 

 to register such species out of the two eolations « aw not yet 

 recorded from the Marmarica, or at least the n«ghtomhotf of 

 Mirsa Matruk. Dr. Ball informs me that his plans came from an 

 area situated between the coast (from a point about 5k n . est o 

 the fort of Mirsa Matruk to Ras Allem Rum) and a hue about 

 15 km. inland, and that they were collected m March, April ana 

 May of 1903. The soil is mostly a calcareou loam - ^ £££
