FLORULA HONGKONGENSIS. 343 



6. Asplenium (Darea) davallioides ; parvum csespitosum, frondibus 

 ovatis acuminatis subcoriaceis subtripinnatis glabris, pinnis prima- 

 riis secundariisque ovatis acuminatis, tertiariis bi-trifidis laciniis line- 

 ari-oblongis patenti-recurvis acutis soriferis, soris totum fere mar- 

 ginem superiorem occupantibus, stipite rachibusque compressis alatis 



et lineatis.

Specimen young, and not fully developed. This is one of those 

 Davallioid Asplenia, which unites the two genera, Bavallia and Asple- 

 nium (§ Bared) ; having however in the present instance quite the ha- 

 bit or aspect of the Dareoid group of Bavallia, but the indusium, that 

 of an Asplenium, elongated and running parallel with the margin, is not 

 in the least cup-shaped, nor attached at the two extremities. The 

 stipes and the rachises are so broad and so much compressed, and 

 so much of the texture of the frond, that it is difficult to say whe- 

 ther the term pinnate or pinnatifid should be applied to the divisions. 

 Stipes 3-4 inches long; frond about the same length, the ultimate 

 segments all recurved (falcately), which is a striking character in this 



sprfbies.

 This fine species is quite new to China.

I refrain from quoting many synonyms, for no one can consult the 

 different views of botanists upon the species of the old genus Bipla- 

 zium (itself a very dubious genus), without seeing that it is in the ut- 

 most state of confusion. Asplenium diver sifolium, Wall., may probably 

 with safety be referred to this. Both are alike in habit, and both have 

 the veins free, and as represented at our t. 56 B of ' Genera Filicum.'
