 less fragrant. Calyx monophyllous, forming a short cylinder, 4-lobed at the

 patent and even reflexed. Stamens eight, united into a white fleshy tube for

39538 to 39541. Pyrtjs spp. Malacese. Pear. 



From Jamaica Plain, Mass. Presented by Prof. C. S. Sargent, Arnold 

 Arboretum. Cuttings received December 7, 1914. Quoted notes by Prof. 

 Sargent. 



39538. Pyrus bretschneideri Rehder. 



"(No. 2.) 452-4. Raised from seed sent to the Arnold Arboretum from 

 Peking, China, by Dr. Bretschneider. A pear with yellow, globose, juicy 

 fruits, of fair quality, which we call Pyrus bretschneideri. Of great value 

 as a decorative plant and, judging from the quality of the fruit, it has 

 economic possibilities. I believe it is from this species that the best 

 Chinese pears are derived." 



39539 and 39540. Pyrus phaeocarpa Rehder. 



" Raised from seed sent to the Arboretum from Peking, China, by 

 Dr. Bretschneider. This species has very small brown fruit. Of great 

 value as decorative plants." 



39539. (No. 3.) 452-7. Fruit globose in form. 



39540. (No. 4.) 452-9. Fruit pyriform. 



39541. Pyrus ovoidea Rehder. 



"(No. 5.) 4033. This is remarkable among pears in having ovoid, not 

 obovoid, fruit. The fruit is of fairly good quality, and the tree has 

 ornamental value on account of its large and abundant flowers and its 

 good foliage which, unlike that of any other pear tree, turns to brilliant 

 scarlet in the autumn. Judging by the shape of some of the Chinese 

 fruits of which you have recently sent us photographs, this may be the 

 origin of some of the cultivated Chinese pears. It is possible that one 

 of the parents of the Kieffer pear may be this species. We know P. 

 ovoidea only as a cultivated tree. It has long been cultivated in the 

 Arboretum as J', simonii, under which name we had it from Kew, where 

 in turn it had come from the museum in Paris. P. simonii, however, is a 

 synonym of P. vssuriensis." 



39542 and 39543. 



From Littleriver, Fla. Presented by .Mr. C. T. Simpson. Received De- 

 cember 2, 1914. Quoted notes by -Mi'. Simpson.

 "A large tree from tropical Asia with dark-green bipinnate leaves and 



spiral pods of lenticular, brilliant red beans. These are used for food
