106 ASPLENIUM ATTEXUATUM. 



greatly with other species. It is a Fern requiring no special 

 care in its management; over-potting, however, should be 

 avoided. But little is apparently known of the Asj)lenium 

 attenuatumy although introduced into England as early as the 

 year 1825. Of late years, however, it has become more 

 generally cultivated. 



An evergreen green-house Fern. 



Native of New Holland. 



Fronds often scarcely divided, but becoming pinnate when 

 of mature growth; sessile, or with longish stalks, becoming 

 proliferous at the apex; linear-oblong, with a very much 

 lengthened and attenuated point; pinnatifidly lobed below, or 

 there distinctly pinnated, the lobes or pinnae sub-rotund; the 

 marghi serrato-dentate. 



The stipes and rachis conspicuously scaly, with narrow 

 blackish scales. 



The fronds rise from a short, erect caudex. 



Length of frond from six to twelve inches; colour dark 

 sombre green. 



The sori are large and comparatively few, though occupying 

 much of the lower surface; they are oblique or transverse, yet 

 less so than often happens in other species, and the uppermost 

 ones appear at first sight to be almost longitudinal; on the 

 lower part of the frond, and especially when the development 

 is sufficiently vigorous to throw out the pinnae there distinct 

 from each other, they are much more obviously oblique. 



My thanks are due to Messrs. A. Henderson, of Pine-apple 

 Place, and Mr. R. Sim, of Foot's Cray, for plants of this 

 species, and to Mr. Norman, of Hull, for fronds. 



It is in the Fern Catalogues of ]\Iessrs. A. Henderson, of
