In the vicinity of mount Apo are at least six species of 
Solanum, more in number of species and representing a 
greater diversity in habit than in any other locality in our 
Archipelago. The list here presented is interesting, not only 
on account of the four novelties, but also because of the 
extreme habits these few species assume. With the excep- 
tion of one lowland species, they are all alpine and all 
are ligneous. S. crassipetalum Wall. is a low ligneous or sub- - 
herbaceous plant; S. verbascifolium Linn. and S. apoense Elm. 
are erect shrubs; S. angatii Elm. is an epiphyte; S. manu-
