42777. Gleditsia caspica Desf. Csesalpiniacese. Honey locust. 

 A very spiny tree, 30 to 40 feet high, the spines slightly flattened, 6 



inches or more long. The flowers are green, almost sessile, in dense, 

 downy racemes 2 to 4 inches long. Fruit scimitar shaped, about 8 inches 

 long and an inch wide. This species is well worth growing because of 

 its greater sturdiness than the ordinary honey locust and because of 

 the size and number of its spines. (Adapted from W. J. Bean, Trees 

 and Shrubs Hardy in the British Isles, vol. 1, p. 595.) 

 For previous introduction, see S. P. I. No. 4228S. 



42778. Pinus sp. Pinacese. Pine. 

 Received as Pinus parol iniana Webb [=P. pyrenaica Lapeyr.] ; the 



seeds do not agree with our material of this species. 



42779. Pyrus canescens Spach. Malacess. Pear. 

 A probable hybrid between Pyrus nivalis and P. salicifolia, between 



which species it is almost intermediate. This tree is very handsome in 

 spring with its very white young leaves, which become shiny dark 

 green above when mature. The fruit is pale green, with much shorter 

 stalk than that of P. nivalis. (Adapted from W. J. Bean, Trees and 

 Shrubs Hardy in the British Isles, vol 2, p. 289.) 



42780. Ribes flavum Berland. Grossulariacese. Currant. 

 Janczewski (Monographic des Grosseilliers, Memoires de la Soci§te' 



de Physique et Historie Naturelle de Geneve, vol. 35, page 506, 1907) 

 refers to this species as a variety of Ribes aureum, the common golden, 

 or buffalo, currant of the central and western United States. 



42781. Ribes multiflorum Kit. Grossulariacese. Currant. 

 This most striking of the red-currant group has yellowish green flowers 



crowded on slender, pendulous racemes, stems 5 inches long. It is a very 

 good shrub, up to 6 feet high, with perhaps stouter unarmed branches 

 than any other currant. The fruit is roundish, red when ripe ; one-third 

 of an inch in diameter, native of southern and eastern Europe. (Adapted 

 from W. J. Bean, Trees and Shrubs Hardy in the British Isles, vol. 

 2, p. 405.) 



42782 to 42789. Rubus spp. Rosacea. Bramble. 



42782. Rubus hoffmeisterianus Kunth and Bouche. 



A Himalayan species closely related to Rubus gracilis and R. 

 foliolosus, but differing from the former in having all the leaflets 

 suborbicular or broadly elliptic, pilose above, and the flowers in com- 

 pact racemes; and from the latter in the form of the leaflets. 

 (Adapted from Focke, Species Ruborum, Bibliotheca Botanica, vol. 

 72, pt. 2, p. 190.) 



42783. Rubus inermis Pourr. 



This species is listed by Focke as a form under Rubus ulmifolius, 

 a very large-branched plant without spines and commonly with 

 ternate leaves. Of unknown origin. (See Focke, Species Ruborum, 

 Bibliotheca Botanica, vol. 83, pt. 2, p. 154, 1914.) 



42784. Rubus leucostachys Schleicher. 



A British shrub distinguished by its round, bright pink or white 

 petals and densely felted stems, leaves, and peduncles; the fruit 

 is white and insipid.
