360 FLOKULA HONGKONGENSIS. 



similar in composition, with the same number of pinnae, but only 7 

 inches long, and narrow in proportion, of a more rigid texture, and 

 darker colour ; pinnae more sinuose at the margin, less acuminate at 

 the point, the whole under side covered with the copious fructifications. 

 The stipes, though broken in both specimens, is twice as long as the 

 frond in the fertile plant. It is a very fine species.

This state of the plant, with sterile and fertile fronds distinct, though 

 rare in Europe, is not uncommon in India, where also the common 

 form is found, viz. with the lower portion sterile, the upper fertile.

A very variable species it must be confessed, with sterile pinnae, 

 sometimes short and obtuse and entire, sometimes elongated, much 

 acuminated, and deeply and sharply serrated, and lobato-serrate, like 

 the leaves of Comptonia aspleniifolia. Sometimes the fertile pinnae oc- 

 cupy the base, sometimes the middle, and even the apex of the frond. 

 There can be no question but that our 0. Vachellii, as well as the 0. 

 Zeylanica of Kunze, must be united to 0. Javanica.

 bus superioribus basi inferne decurrentibus terminal! maxima elon- 

 gato-laneeolata integris vel subsinuato-lobatis, pinnis fertilibus late- 

 ralibus pinnulis linearibus pinnatifidis. — Osmunda bipinnata, Hook,

Hab. Hongkong, Dr. Harland. 



A most distinct and well-marked species, peculiar, as far as we at 

 present know, to Hongkong.
