very limited.) For trial in the milder parts of California and the Southwest and in 

 the Gulf region. (Chico, Calif.) 



23C14. ASPARAGUS SP . * From China. Collected at Hangchow, Chekiang, by Frank N. 

 Meyer, Bureau of Plant Industry. A very small evergreen asparagus, attaining ordi- 

 narily a height of only ^ to 5 inches. It is used as a border along paths in small 

 gardens and requires a shady situation. The plant endures light frosts without 

 injury. Recent experiments indicate that it may prove useful for pot culture provided 

 it is kept moist and moderately cool and, especially, that it is kept very cool 

 during the development of the new shoots. Under ordinary room temperatures the new 

 shoots become "leggy" and spoil the symmetry of the cluster of plants in the pot. 

 For trial in the middle and lower South and in southern California and elsewhere 

 indoors. (Savannah, Ga.) 



129189. 5AUHINIA SP . (Caesalpiniaceae.) From China. Collected near Opie Hsien, 

 Szechwan Province, by Yu-shin Liu of the Lu-shan Arboretum and Botanical Garden. A 

 shrubby bauhinia with moderately large leaves. (Supply limited.) For trial in the 

 warmest parts of Florida, the Gulf coast, and California. (Glenn Dale, Md.) 



128898. BEC-CNIA SUTHERLANDI . * (Begoniaceae . ) From Pennsylvania. Presented by Mrs. 

 J. Norman Henry, Gladwyne. A tuberous begonia, with slender, bright red-purple stems 

 1 to 2 feet high, translucent ovate-lanceolate leaves, the blades about 5 inches long, 

 and axillary and terminal cymes of many orange flowers, each about an inch in diam- 

 eter. Native to damp shady places at altitudes of 3,500 to 5,000 feet, in Natal.

130480. BETULA UTILIS.* (Betulaceae . ) Birch. From China. Collected in Yunnan by 

 T. T. Yu, with the Yunnan Expedition of the Fan Memorial Institute of Biology, and 

 presented by the Arnold Arboretum, Jamaica Plain, Mass. A tree 40 to 60 feet high, 

 with red-brown trunk and branches, and bark which peels off in papery flakes. It is 

 native to subtropical regions of the Himalayas. The oval, coarsely toothed, sharp- 

 pointed leaves, 3 inches long, are dark green above and paler beneath. In winter the 

 orange-chocolate color of the twigs is very striking. For trial in all but the 

 coldest parts of the country. (Glenn Dale, Md.) 



131057. B0LT0NIA LAUTUREANA . ( Asteraceae . ) From Manchuria. Collected at Harbin, 

 by B. V. Skvortzov. A herbaceous perennial with erect, branching stems not over 2 

 feet high, leathery lanceolate leaves and small panicles of pale-lavender flower heads 

 about l-§ inches across, in late August. Besides inherent merit, it would undoubtedly 

 be of value to breeders. Native to northeastern China. For trial throughout the 

 Northern States. (Glenn Dale, Md.) 



133843. CAESALPINIA MEXICANA. (Caesalpiniaceae.) From Texas. Presented by Peter 

 Heinz, Brownsville. A vigorous unarmed shrub or small tree with bipinnate leaves of 

 rich green. The leaflets are obovate-oblong, about 1 inch long. The flowers are 

 rather large, bright yellow, with long showy stamens, and are borne in very long 

 racemes. For trial throughout the lower South and the Southwest. (Glenn Dale, Md.) 



118761. CALLISTEMON CITRINUS. (Myrtaceae.) Bottlebrush. From California. A 

 selection made at the Plant Introduction Garden, Chico, Calif., from second-generation 

 seedlings of a plant grown in New South Wales as Calliste mon "hortensia." The present
