Some closely allied plants, esteemed mere forms of F. diphylla by Kunfch and 

 Boeckeler, are here regarded as distinct ; even thus narrowed down, our F. diphylla, 

 has 140 names. It should, moreovej, be understood that F. diphylla is so close 

 to the preceding F. dichotoma that different cyparologigts sort the material, a? 

 between these two, differently. The examples from Tropical Africa, above referred 

 to F. diphylla, do not match, so that the species might be further subdivided.

In this genus, no name has been so misapplied and confused both in the text- 

 books atid in the herbaria as F. pilosa. The hairy forms (or varieties) of 

 F. diphylla are immerous and abundant, especially in Malaya; and these are 

 often named in herbaria, probably by guess from the name, F. pilosa, Vahl 

 (which tliey are not) ; and this is the plant reduced correctly by Kunth, 

 Boeckeler, &c. to F. diphylla, Vahl. The true F. piUsa, Vahl has not been 

 much collected, and differs much, essentially in the non-trabeculate nut. The 

 name F. pilosa, K. Schumann, is merely a book synonym for the earlier F. africana^ 

 Durand & Schinz, below, a species of anotlier section.
