326 FLORULA HONGEONGENSIS. 
Professor Miquel, in the Index Sem. Horti Amst. 1849, and in his 
Anal. Bot. Ind. p. 49 (Verh. Kon. Ned. Inst. vol. iv. L. c.), has men- 
tioned as J. longifolia, Grev. et Hook.? (but very prudently with an 
interrogation) an inhabitant of Java. I have received, through the 
kindness of that botanist, all the specimens of his herbarium; but I 
can now affirm that there is as great a difference between this species 
and the specimens of Mr. Mathews, as there can be between any two 
species of this varied genus. The apex in the Javanese specimen is 
sterile, in the Mathews specimens the apices of all the leaflets are, 
without exception, fertile. The bases are generally truncate, not un- 
equally cordate. The colour is not brown, but pale yellow. The 
under surface is not pulverulent, but smooth. The costa, the veins, 
and the veinlets are not brown, but yellow. The sori are not separated, 
but contiguous. The whole structure differs, being not membranaceous 
but coriaceous. 
If perhaps I have been successful in tracing out distinctions in some 
species of a genus of plants, of which other botanists have formed a 
different opinion, I must in this case only thank those gentlemen for 
the opportunity afforded me of thoroughly examining the objects of 
their own investigation.
