166 XLi. SAPiNDACE^. [PcmUinicc 



Paullinia, Aphania, etc., appear quite at the banks of streams in 

 the coast region ; Allophylus africanus, Bersartia paullinioides, as 

 well as a new species of this genus and some other genera, inhabit 

 the virgin woods of the mountainous region (Welw. Apont. p. 562, 

 n. 147). 



Some species of African Sapindaceae are edible ; a species of 

 Chytranthits in the Island of St. Thomas is often called by the 

 Portuguese colonists "Pecego" (peach); also certain species of 

 Aphmiia produce edible fruits. The genus Ptctroxylon (Sneeze- 

 wood) is very remarkable on account of the wood exciting sneezing; 

 it occurs not only at the boundary of the equinoctial circle, but 

 even within 7° to 9° south latitude in the hilly or interior portion 

 of the littoral region. Some affinity exists between Sapindaceae 

 and Euphorbiacese through the medium of the Euphorbiaceous 

 genus Hymenocardia, the flowers and fruits of which remarkably 

 resemble a species of Dodoncpxt, and even their structure is suffi- 

 ciently similar, although the presence of albumen in Hymenocardia 

 and the structure of the embryo easily prove an ordinal difference ; 

 moreover, Oldfieldia has been placed successively in the two 

 Natural Orders.
