long. Lnmina rhomboid, Sfoetlonp;, ti foot broad, narrowed to both 

 ends, cut down nearly to the rachis throughout into simple, close, 

 patulous, lanceolate, acuminate pinnae 1-1-| inch broad. Pinnae 

 about 20-jugate ; wing of main rachis an inch broad. Texture 

 membranous ; rachis and surfaces quite glabrous. Main veins 

 rather distinct halfway to the edge ; areolae fine, with copious, 

 free, inchxded veinlets. Sori round, not immersed, scattered irre- 

 gularly, 3 or 4 between midrib and edge. This is the Saraoan 

 plant we have referred to P. dilatatum, but this fuller supply of 

 specimens shows it to be distinct. It differs from the Himalayan 

 plant by its much less numerous, larger sori and less distinct 

 main veins. It is probably the Brynaria acuminata of Brackon- 

 ridge's Perns, p. 47, but he has used the same name for a totally 

 different plant at p. 41.

Br H. F. Hance, Ph.D., &c. 



In the early spring of the present year I had the opportunity of 

 passing five days at Saigon, the capital of French Cochinchina, where 

 it was my privilege to make the personal acquaintance of M. Louis 

 Pierre, Director of the Botanical Gardens. This gentleman, who is 

 ardently devoted to botany, has explored with the greatest perse- 

 verance and resolution, sometimes at the risk of his life, various portions 

 of the little-known interior of Cochinchina and Cambodia, and has 

 collected several thousand plants, all of which he has preserved by 

 poisoning, and packed away in chests for ultimate distribution, having at 

 the time of collection made careful notes, and frequently also dissections
