 " Cctte foiigerc a un port special trus-distinct de celiii des autres Aspidiecs ;" this 

 is very true, but to nie this seems to be an abnormal state : a fertile frond un- 

 usually contracted and unnaturally irregular in outline, and with a good deal the 

 habit of small contracted specimens of Aspid. coadunalum. Wall., so that could 

 we see the sterile fronds, they would perhaps exhibit the ordinary venation of 

 Sagenia. My only two specimens are, as regards venation, quite uniform.

llab. Penang, Wallich. Borneo, De Vriese and Teijsmann, n. 46. — The only 

 specimens I have seen of this rare and yet undescribed sagenioid Aspidium, are 

 from Fciiang and from Borneo ; the specimens are destitute of caudex, and are 

 remarkable for the long, narrow, ribbon-like pinnules. The pinnte are opposite 

 or alternate, the lowest pair are compound and the divisions long-petiolcd. The 

 venation is that of Cardiochlcuna, Foe, that is, with free veinlets in th.e areoles of 

 the venation. I regret the fructification is very scanty and too young to enable 

 me to form an idea of the perfect form of the involucre ; probably it would be 

 like that of Aspid. Lohbii, an allied yet very distinct species in the venation, etc.
