POLYSTICHUM ANGULARE. 



opposite; at twelve Indies from the base the frond divides into 

 two strong flexuose branches, with ascending and very crowded 

 pinnae and pinnules, sonic of the pinnae taking the form of 

 branches, being six inches long and two and a half broad, these 

 branches go on dividing and dividing, forming a head as dense 

 as a forest nearly a foot across. A most magnificent, and the 

 most densely ramose variety I have seen. My thanks are due 

 to the Rev. F. Mules, of Marwood, for fronds.

 in conijiany with some plants of Grandidens, by Miss Thompson, 

 of South Lawn, Exeter. A thin-frondcd form, very acute, 

 fifteen inches in length, and only two wide in the widest part.

 Pinna) unequal in size, varying from two or three pairs of 

 pinnules to seven or eight pairs, the apex sometimes acute and 

 sometimes blunt. Pinnules very various in shape and size,

 slightly spinous; always a spine at the apex of the pinnule. The 

 apex of the frond much attenuated. I am indebted to Mrs,
