POLYPODIACEAE

 Asplenium bireme Wright in Kew Bull. (1908) 182. 





Asplenium chlorophyllum Baker in Jour. Bot. (1885) 104; Bedd. in Handb. Suppl. 39 (1892). 



Caudex rather thick, oblique; scales none or very small and obscure; stipes dense- 



* * t 



ly tufted (3-5 together), 12-17 cm. long, sordid blackish at the base, growing greenish 

 upward, densely clothed like the entire main rachis with shaggy rather stiff, brown 

 glandular hairs; frond 20-38 cm. long, 12-15 cm - broad at the middle, which is the 

 broadest part, ovate-oblong, narrowed very gradually towards the apex and reduced 

 towards the base, simply pinnate, rachis densely pilose; pinnae 20-25 on each side, 

 alternate, moderately close, lanceolate, acuminate, crenate, the lower ones sessile, the 

 middle ones adnate, the uppermost ones connected by a broad wing under the pinnatifid 

 acuminate apex, those in the upper half of the frond horizontally patent, the basal ones 



* . 



strongly deflexed, the largest to 7 cm. long, 1.5 cm. broad, distinctly auricled on the 

 upper side at the base, rounded or slightly cut away below; veins distinct to the margin, 

 transluscent, forked once or twice, but pinnate in the auricles; sort linear, borne on the 



- 



anterior veinlets and extending from the costa to more than half way to the margin, 



■ 



slightly curved, about 5 mm. long, rarely diplazioid, inducium moderately broad, 

 persistent, not ciliate; texture thin papery, bright green, densely villose on both surfaces, 

 and especially along the costae beneath. 



Distribution: Kwangtung, Kwangsi, also Formosa and Penang. 



A medium-sized and very distinct fern, characterized by all parts being densely 

 villose and rarely diplazioid sori. Baker's diagnosis for his Asplenium pullingeri was 

 evidently based upon a rather smaller plant then grown in Kew Gardens perhaps from 

 the rootstocks sent to that institution by Mr. Pullinger from Hongkong, 1871. His state- 

 ment, "its very short stipes" is certainly incorrect, as the specimens collected in Tai-mo- • 

 shan, Hongkong New Territory, where most likely be the type locality for Baker's 

 species, by E. H. Wilson and W. T. Tutcher, upon which Wright based the description 

 for his Asplenium bireme, has stipes to 30 cm. long, and Matthew's plant, No. 280 

 (February 4th. 1907), from Ma-on-shan in the same locality, upon which our present 



■ 



figure is based, has stipes from 12 to 17 cm. long.
