P. cognata n. sp. Stands near P. stenocalyx Maxim., with which 

 it agrees in foliage, bracts, the narrow calyx-lobes and the length 

 of the rugose corolla-tube; it differs in the much longer pedicels 

 and in the calyx-tube, which is prismatically angled.

Hayata, B., On Taiwania, a New Genus of Coniferae from the 

 Island of Formosa. (Journal of the Linnean Society of London. 

 Vol. XXXVII. No. 260. 1906. p. 330—331. Plate 16.) 



The new genus has the habit of a Cryptomeria and has very in- 

 teresting cones, which seem to bring it nearest to Cunningliamia; 

 the cones of the two genera are similar in the arrangement of the 

 seminiferous scales, in the minute bracts, in the attachment and po- 

 sition of the ovule, and in the shape of the seed, wing, albumen, and 

 embryo; but they differ in that Taiwania has no secondary squamae 

 and in their being two ovules to each scale. The diagnosis of the 

 new genus is as follows: 



Flores monoici? ,^ O. Strobilus subg'lobosus, bracteis 



minutissimis; squamae multiseriatae laxiuscule spiraliter imbricatae 

 parum induvatae apice squarroso-patentes persistentes obovatae 

 apice leviter mucronatae basi cuneatae. Semina ad medium squa-
