Hayata, B., On Tawania, a new Genus of Coniferae from the 

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

 XXXVII. p. 330—331. pl. 16.) 



This very interesting Conifer was obtained by Mr. N. Konishi, 

 on the western slope af Mt. Morrison at an altitude of about 2000 

 meters. The plant is very interesting on account of the remarkable 

 form of the cone. The habit is just that of Cryptovneria , while 

 the cone bears much resemblance to Ciimiinghaniia. In external 

 appearence, the cone is like that of Tsiiga, but differs so greatly in 

 its structure that this hardly needs pointing out. The plant comes 

 nearest to Cunninghaniia in the structure of its cones i. e. in the 

 arrangement of the seminiferous scales, in the presence of the minute 

 bract, in the attachment and position of the ovules and in the shape 

 of the seed, wing, albumen and embryo. But it differs from the 

 latter by the absence of the secondary squama and the number of 

 the ovules which is decidedly two on each scale. These two points 

 and the even more strikingly different habit of the plant, are the 

 essential points upon which the new genus Tawania Stands.
