Plants recently received, not yet available for distribution. 
ACER spp. (Aceraceae). Maple. From Darji ling, India. Seeds 
presented by G. H. Cave, curator, Lloyd Botanic Garden. 
For many years, Mr. Cave has sent annually to this Office seeds 
collected from the plants under his charge, and from the surrounding 
region. Many of them, naturally enough, have proved too tender for 
cultivation in most parts of the United States. Darjiling lies at 
the upper edge of the subtropical zone, and its climate is sufficient- 
ly mild to permit the cultivation of plants like Erythrina arborescens, 
which repeated trials have shown to be scarcely hardy in California. 
The Lloyd Botanic Garden contains, however, many plants from higher 
elevations, whose cultivation should be practicable throughout a fair- 
ly wide area in the United States. 
The three maples which Mr. Cave has sent, and which are briefly 
characterized below, are suggested for trial in the South Atlantic and 
Gulf Coast States, and will be propagated for that purpose. 
58901. ACER campbellh. Described as a handsome tree, whose 
bright-green foliage contrasts prettily with the red stalks and twigs. 
The timber is used in India for cabinet work and for planking. 
58902. ACER hookeri. A handsome tree 40 to 50 feet high, with 
deeply fissured brown bark, native to the Sikkim Himalayas at alti- 
tudes of 8,000 to 10,000 feet. The oval leaves, though usually green, 
are sometimes copper colored. The wood is gray with small pores and 
numerous fine red medullary rays. 
58903. Acer laevigatum. A tree with a broad low crown, yellowish 
or ash-colored bark, and leaves of pleasing green. The hard, close- 
grained shining white wood is popular in Nepal for building purposes. 
citrus grandis (Rutaceae), 58840. Grapefruit. From Ancon, Canal 
Zone. Budwood presented by W. T. Robertson, Pedro Miguel, Canal Zone, 
through James Zetek, Ancon. This is a rare and interesting variety of 
grapefruit said to produce fruits with juicy flesh of blood red. Its 
origin is uncertain, but it seems probable that it was brought from 
Asia in the early days of trans- Isthmian travel. Red-fleshed grape- 
fruits, or pomelos, are common in India, but they usually lack juice 
and are quite different from the grapefruit of Florida in general char- 
acter. Some of the Indian varieties have been introduced into the 
United States, where they have failed to become popular. A pink- 
fleshed grapefruit, which originated in Florida as a budsport from one 
of the standard commercial sorts, has met with a more favorable recep- 
tion, but has not attained commercial importance. 
If the variety which Mr. Robertson has sent proves to be of good 
quality, and at the same time has flesh of attractive red color, it 
will be a novelty of much interest. In forwarding the budwood he says:
