42577 to 42580— Continued. 



42579. " Dwarf, bushy, 2 to 2£ feet high, white flowers, white seeds, 

 pods small, flat, averaging three seeds each. Grown by the coolies 

 here. This is not to be compared for usefulness with the white-seeded 

 Nankin icus." 



42580. "A white-flowered kind much used by the coolies." 



42581 to 42595. 



From Kew, England. Presented by Sir David Prain, director. Royal 

 Botanic Gardens. Received April 20, 1916. 



42581. Prunus cornuta (Wall.) Steud. Amygdalacea?. 



Himalayan bird cherry. 

 " A deciduous tree, 50 to 60 feet high in a wild state. Leaves deep 

 dull green above, paler beneath; flowers white, densely set on cylindrical 

 racemes, 3 to 6 inches long, three-fourths to 1 inch wide; each flower 

 is one-fourth to one-third inch across. Fruit round, one-third of an inch 

 in diameter, red, changing to dark brown-purple. Flowers in May. Native 

 of the Himalayas, where it is widely spread up to 10,000 feet and repre- 

 sents in that region Prunus padus. So nearly are they allied that many 

 botanists regard them as forms of one species. According to travelers 

 in the Himalayas, P. cornuta grows to considerably larger size than 

 does P. padus, as we know it in England. The name cornuta (horned) 

 refers to the shape of the fruits as often seen in the Himalayas. An 

 insect deposits its eggs in the young fruit, and as the larvse develop 

 they set up irritation and cause a curious growth, which is from 1 to 

 2 inches long and curled like a horn. It is analogous to the many galls 

 that occur on our own trees, notably oaks." (IV. J. Bean, Trees and 

 Shrubs Hardy in the British Isles, vol. 2, p. 233.) 



42582. X Prunus eminens Beck. Amygdalacese. Hybrid cherry. 

 "A small pretty tree similar to Prunus acida in flower, but of mora 



open growth ; is described as a hybrid between it and P. fruticosa." 

 (\V. J. Bean, Trees and Shrubs Hardy in the British Isles, vol. 2, p. 227.) 



42583. Prunus incana (Pall.) Stev. Amygdalacese. Willow cherry. 

 " A deciduous shrub, 4 to 8 feet high, of rather open, loose habit. 



Leaves dark green and smooth above, covered with a close white wool 

 beneath. Flowers one-fourth of an inch across, borne singly from the 

 buds of the previous year's shoots; petals deep rosy red. Fruit smooth, 

 red, one-third of an inch across. Native of southeastern Europe and 

 Asia Minor; introduced in 1815. Its flowers appear in April along with 

 the young leaves, and it is then very pretty. Sometimes confused with 

 Prunus nana, it is easily distinguished from that and most other species 

 by the close white felt on the under surface of the willowlike leaves. 

 The fruit is quite different from that of /'. nana, being cherrylike." 

 ( W. I. Bean, Trees and Shrubs Hardy in the British Isles, vol. 2, p. 238.) 



42584. Prunus maximowiczii Rupr. Amygdalacese. Korean cherry. 

 "A deciduous tree up to 20 or 30 feet high, with a slender trunk. 



Flowers rather dull yellowish white, about five-eighths of an inch across, 

 produced in mid-May on stalked racemes, remarkable for the large loaf- 

 like bracts with which they are furnished. Fruit globose, one-sixth of 

 an inch wide, shining, at first red, then black; ripe in August. Native
