          followed by a profusion of strikingly attractive bright-red berries. 
This shrub has proved a very desirable ornamental and will doubtless 
be grown more extensively in this country. It is propagated from seed, 
by layering, or from cuttings.

32935. COTONEASTER MICROPHYLLA THYMIFOLIA. Fire Thorn. From 
the Himalayas of northern India. Seeds presented by Prof. Alwin 
Berger, La Mortola Botanic Garden, Ventimiglia, Italy. A dwarf, prostrate 
or trailing shrub with persistent leaves, pinkish white flowers, 
and bright-red fruits. This is an attractive small plant, suitable 
for rockeries.

52603. DELOSTOMA ROSEUM. Cholan. From Ambato, Ecuador. Seeds 
collected by Wilson Popenoe, Agricultural Explorer. A small, somewhat 
spreading tree of southern Ecuador, where it grows in the Andes at 
elevations of 6,000 to 10,000 feet. It is shapely and attractive in 
appearance, and produces at the ends of the branchlets small clusters 
of dark lilac flowers resembling in form and appearance those of 
the trumpet vine. As it is not very frost-resistant, it is probably 
suitable for cultivation only in California and Florida.

52609. DELOSTOMA ROSEUM. From Ambato, Ecuador. Seeds collected 
by Wilson Popenoe, Agricultural Explorer. Like the preceding except 
that the flowers are of a pale shade of lilac.

53610. DENDROCALAMUS STRICTUS. Bamboo. From Dehra Dun, India. 
Seeds presented by R. S. Hole, Forest Botanist. The culms of this 
rapid-growing bamboo are usually solid and in India sometimes grow to 
a height of 70 feet; they are curved near the tips, giving them a highly ornamental, plumelike effect. The species is reported to be resistant to light frosts. It is a clump bamboo, and in consequence spreads 
very slowly. The strong, durable timber is highly valued for building 
and other purposes.

37943. DIOSCOREA ALATA. Greater, or Ten-months' Yam. A West 
Indian variety of the true yam, cultivated sparingly in Florida. It 
is not related to the sweet potato, some varieties of which are called 
yams. The tubers of this plant, which sometimes reach a weight of 10 
pounds or more each, are white-fleshed, and in composition are similar 
to the white potato, from which they can scarcely be distinguished 
when properly cooked. Yam tubers, when properly handled, may be 
stored over a long period without appreciable deterioration. For cultivation 
a deep mellow soil and a growing season of 9 to 10 months 
are required, but the plant is a handsome vine and may be grown for 
porch decoration where the season is much shorter. This yam deserves 
much wider cultivation in Florida for home use and for markets.

39705. DIOSCOREA ALATA. Guam Yam, or Dago Haya. From Guam. A 
variety of the greater yam with purple inner skin and white flesh 
sometimes slightly tinged with purple. The flesh darkens somewhat 
when cooked, but possesses a rich flavor. The tubers are often large 
and of irregular shape. The vine is easily distinguished from that of
