 coriacejim, as it is also to the following, Aspid. Seemanni. 



40. A. (Polystichuni) Seemanni, Hook. ; caudex ? stipes ? 

 frond (in my solitary specimen) nearly 1 h foot long broad 

 deltoideo-ovate acuminate bipinnate coriaceous, beneath on 

 the rachises minutely subglanduloso-pubescent regularly 

 bipinnate, primary pinnae petiolate lower ones a span long 

 distant, pinnules also distant I an inch to 1^ long, the 

 largest petiolate oblong obtuse truncate but subauricled at 

 the superior base lobato-pinnatifid, the lobes entire smaller 

 and upper ones sessile subdecurrent and entire or only 

 slightly sinuated, costule beneath very prominent straight, 

 veins pinnated with fine veinlets also prominent and flexuose, 

 each veinlet soriferous at the apex, involucres convex sub- 

 umbonate orbicular and peltate deciduous. (Tab. CCXXX.) 



Hab. Bay of Ardita, tropical Pacific America, Seemann. — I have seen only one 

 specimen of this very distinct Aspidium, and this destitute of caudex and stipes, 

 wliich will he found probably to resemble those of A. coriaceum and Berteroanum, 

 to which group this plant undoubtedly belongs. The venation is very peculiar, 

 and the frond seems to be quite destitute oi scales. 



41. A. (Polystichum) melanostictum, Kze. ; " frond large 

 ovato-acuminate submembranaceous paler beneath bipinnato- 

 pinnatifid pinnato-pinnatifid at the apex, pinnae alternate re- 

 mote petiolate erecto-patent lanceolato-acuminate, pinnules 

 sessile decurrent at the base lanceolato-acuminate deeply 

 pinnatifid, segments oblong subfalcate acute coarsely serrated 

 or incised cuneate at the base, sori numerous between the 

 costule and the margin arranged in a line round plane at 

 length spreading, involucres orI)icular persistent cinnamon- 

 coloured the disk black, stipes and rachises sulcate paleace- 

 ous hairy, costa3 and costules hairy above paleaceous be-

Hab. Mexico: Cuesta grande de Chicanquiaco, temperate region, Schiede ; 

 Xalapa, Galleotti, n. 6320, Harris. — My specitnens, though otherwise very per- 

 fect, are, like those of Kunze, destitute of caudex and stijjcs. The author de- 

 scribes it as " species insignis habitu Aspid. catoptcri mihi (Lastrea lanuginosa.
