Affinities. 

 With E. strlcta Sieb. and E. apieulata Baker and Smith. 



Its closest relations are with these two species, but their 

 fruits are always urceolate or ovoid, and not cylindroid 

 or ovoid-oblong. The leaves are broader than those of E % 

 apieulata and resemble those of E. stricta a good deal, 

 but those of the new species are more copiously dotted and 

 possess the appearance of an almost serrulate margin. 



The new species is referred to in O.R., ix, 283, under E. 

 stricta. The specimen from Blackheath referred to as "B" 

 (Maiden and Oambage) has prominent spreading, usually 

 well-defined venation, with the fruits inclined to be barrel- 

 shaped. This puzzling form is still under investigation for 

 it has affinities with other Renantherse. 



E. approxlmans is a member of a trio (the other two 

 members being E. stricta and E. apieulata) that are not 

 easy to separate. Thus the two latter can only be separated 

 by a convention (width of suckers, a variable, like all other 

 characters, see O.R., Part ix). The same thing may be 

 said (perhaps quoting other characters) of other geminate 

 species. But it seems to me that, in the important matter 

 of fruits, those of E. stricta and E. apieulata are always 

 urceolate, or approximate thereto. In specimen "B" the 

 primary shape appears always to be that of a barrel, while 

 in E. approximans the shape is always cylindroid. I have 

 raised seedlings of "B," E. apieulata, (E. stricta may be 

 omitted, as less close to E. approximans than E. apieulata) 

 and E. approximans. Those of "B" are for the most part 

 with stem-clasping leaves, and have no close affinity to the 

 last; those of E. apieulata and E. approximans present 

 certain differences that are difficult to make clear without 

 illustrations. 



I have already shown how close the species is to the E. 

 stricta series, but although I have examined the relation-
