146 Remarks on the species of Pandanus. [No. 3, 



I have formerly believed, having lain too much stress upon the num- 

 ber and the position of the ovules. Graudichaud's genus Sussea, and 

 especially Souleyetia Freycinetioides make it now even difficult, to re- 

 tain Pandanus and Freycinetia as distinct genera. The only differences 

 of some value, to distinguish thern, seem to rest in the general habit, 

 and the more or less regular superposition of the pendulous ovules 

 along the marginal placenta. The ripe seeds in Freycinetia seem all 

 to be furnished with a black and hard testa, while in Pandanus, they 

 are only covered by a white membrane. 



In revising Gaudichaud's species, I am now able to rectify my 

 sections, formerly proposed, and I do this in recapitulating at the 

 same time all the legitimate species, but omitting all those dubious 

 ones, which have been already enumerated in my above quoted 

 paper. It is impossible to form a correct idea, how far several 

 of Graudichaud's species of Pandanece are really identifications with 

 Bory St. Vincent's Mascarhen species, bearing homonymous specific 

 names, as the plates are accompanied only by an incomplete explana- 

 tion of the figures. My own idea is, that they are most probably 

 respective identifications ; Gaudichaud's Roussinia Indica, 1. c. t. 21, 

 at least, is a copy of Rheede's figures of Perin Kaida (Pandanus 

 unipapillatus, Ptennst.) 



Dr. P. von Miiller has recently published some notes on Australian 

 Pandanece, mentioning therein two additional species of Pandanus, 

 P. aquaticus, and P. monticola, F. Muell. {Fragment. Phyt., V, p. 40). 

 Unfortunately the names of these species are not accompanied by 

 a description.
