Chosenia is a very remarkable genus of Salicaceae only recently dis- 

 covered and without seeing the flowers no one would consider it distinct 

 from Salix. The staminate catkins are drooping, the bracts are imbri- 

 cated and membranaceous and the five stamens adhere halfway to the 

 bracts. The female catkins also are drooping, the bracts are membrana- 

 ceous and caducous and the two distinct styles are subterminal and ar- 

 ticulated at the middle. I would like to make a new subfamily, Cho- 

 senieae, for this genus distinguished from Saliceae which would include 

 Salix and Populus by the two distinct and articulated styles and by the 

 ovary having neither a gland nor a cupula at the base. There is an 

 analytical figure of a fruiting catkin drawn by C. Schneider in the her- 

 barium of Arnold Arboretum, in which the scar of the bract is errone- 

 ously designated as the gland; this explains the fact that in his descrip- 

 tion of this species he attributes a gland to the pistillate flower. 



Chosenia grows quickly and its trunk is straight becoming often more 

 than 1 meter in diameter. The wood is the hardest of all known Salica- 

 ceous trees in Korea and is used especially for bridge building. The 

 Japanese make wooden clogs from it. The fibres are used for making 

 rope and sandals by the Koreans.

 Celtis Biondii v&r.heterophylla Schneider in Sargent, PI. Wilson, in. 282 (1916). 



This species is distinguished from Celtis Biondii by the following char- 

 acters. 



Celtis Biondii: Folia cum acumine 5-9 cm. longa, 3.5-5 cm. lata, adulta 



utrinque nervorum axillis infra barbatis exceptis glabra. Flores hermaph- 

 roditi; perianthii laciniae 2.5 mm. longae 0.5 mm. latae. Bacca nigra. 



Celtis Leveillei: Folia cum acumine 2-8 cm. longa, 1-3.5 cm. lata, adulta 

 supra sparse scaberulo-ciliata, infra ad venas primarias pilosa. Flores 

 monoeici; perianthii laciniae 2 mm. longae 1 mm. latae. Bacca aurantiaca. 



I had not seen flowers when I described this species in the Tokyo 

 Botanical Magazine and may add the following description: 



Flores masculi e gemmis baseos rami evoluti pauci; pedicelli 3 mm. 

 longi, pilosi, graciles; perianthii laciniae elliptica vel obovato-oblongae, 

 2 mm. longae et 1 mm. latae, dorso pilosellae castaneae; stamina 4, laciniis
