PLANT INTRODUCTI ODES TWENTY EIGHTH ANNUAL DESCRIPTIVE LIST

Season 1939-40

Containing Descriptions of the More Important Introduced Plants Now Ready

for Listed Experimenters

Division of Plant Exploration and Introduction Bureau of Piant industry United States Department of Agriculture

Washington, D. C.

All plants sent out by this Division to experimenters are inspected at the Plant Introduction Gardens by officers of the Bureau of Entomology and Plant Quarantine. At the time this Annual List goes to press the inspection has not been made. It is possible, therefore, that quarantine

regulations may prevent the sending out of a few plants herein described.

PLANT INTRODUCTIONS

Experimenters will please rea note before sending in their

This, the Twenty—-eighth Annual List of Plant Introductions, contains descrip- tions of many new and rare plants, not yet widely tested in this country. he available information concerning some of them is meager, and it is therefore impossible to speak with assurance regarding their value, their cultural requirements, and their adaptability to the various climates and soils of the United States.

These plants have been imported because it is believed some direct or indirect use can be made of them. They are first placed at the disposal of the experts engaged in plant breeding, crop acclimatization, and horticultural investigations generally in the United States Department of Agriculture and the State Experiment Stations. Some of them have been grown in sufficient quantity, however, so that they can be distributed to some private experimenters who have the facilities to test them carefully. The List is therefore sent to those who have qualified as experimenters with the Divi- sion of Plant Exploration and Introduction, and who have indicated a willingness to care for material sent then.

Accompanying this Annual List are complete Check Lists showing all plants avail- able for distribution at the several Plant Introduction Gardens during the season 1939-40 and the Garden from which available. Applicants for material should fill out all blanks at the top of the Check List of each garden from which they request plants, place a mark to the left of the P. I. (Plant Introduction) number of each plant desired, and return the lists promptly to this Division. Items marked with an asterisk (*) are available in somewhat larger numbers, for propagating purposes, to interested nurserymen having exceptional facilities.

It should be distinctly understood that the Division does not agree to supply all the plants requested. It reserves the right to limit the number or to withhold the entire request of any experimenter in order that it may place the material according to its best judgment.

The shipping season extends, as ar may not always be practicable to ship plants at the time preferred by experimenters, it is much desired that when such preference exists it be indicated in the space provided for it at the head of the Check List.

These plants are placed in the hands of experimenters with the understanding

on their r will be sent to this Division from time to time, par-

ticularly noting their flowering, fruiting, hardiness, utilization, and any other interesting features. Reports should be prepared (preferably, but not necessarily, on regular forms) and sent, without special request, whenever in the judgment of the experimenter the plant has reached a stage that makes a report worth while; usually, however, unless the plant has flowered or died, reports should not be made within the first year or two. Regular report forms will be furnished by this Division, upon request. When all the plants of any P.I. number have died, this should be reported promptly by letter, with the cause of death indicated when known. It is expected that

that reports on their behavio r

showing the location and P.f. number of each one. Failure to comply with these direc- tions will be considered sufficient reason for a discontinuance of the cooperative relation.

For the convenience of Experimenters, the bamboos of which plants are available are listed all together here. The shipping weight ranges usually from 1 to 2 pounds per plant. Bamboos in general require a moderately moist but well-drained soil, of good fertility. Attention of experimenters is directed to the fact that small bamboo plants, even more than most other plants, require frequent watering until wll

established; this means for at least 2 or 3 months after planting.

93573. BAMBUSA LONGISPICULATA. (Poaceae.) From India. Presented by R. N. Parker, Forest Botanist, Forest Research Institute and College, Dehra Dun, United Provinces. A tropical clump bamboo growing to 50 feet high, with 10 to 12 leaves up to 9 inches long, on a branchlet. For trial in the warmer parts of southern Florida and southern California. (Savannah, Ga.)

99289. BAMBUSA MULTIPLEX.* Hedge bamboo. Presented by Jas. H. Wells, formerly of Baldwin, Fla., who obtained it from C, EB, Pleas, Chipley, Fla. Variety Disticha striata. An oriental fern-leaved dwarf variety of the hedge bamboo in which the culms, or stems, are more or less pinkish, with slender green stripes. The varietal characteristics are somewhat unstable, however, and if small plants are grown in rich soil in the open there is a tendency to revert to the larger parent form; the striping of the culm then disappears and the foliage changes from the fern-leaf type. In its dwarf phase the plant grows about 6 feet high but in the reverted form it attains 15 feet or more. It endures temperatures down. to about 16° F. with little or no injury to the foliage.

77013. BAMBUSA VENTRICOSA.* Buddha bamboo. From China. Presented by Lingnan Uni- versity, Canton. A clump-forming bamboo growing up to about 25 feet high in the open but commonly grown by the Chinese as a pot or tub plant. Under this culture it is dwarfed to about 3 feet and the internodes of the culms and branches become swollen in a characteristic manner, to which fact is due the Chinese name Fut_t'o chuk (Buddha's belly bamboo). The plant quickly loses its foliage in the dry atmosphere and deficient light of ordinary living rooms. The lanceolate leaves of the dwarfed plants are 1 to 4 inches long but on larger plants in the open the leaves are nearly twice as long. As grown in the open this bamboo is reported to have withstood tem— peratures down to about 20° F. with little or no injury. For trial outside in the milder parts of Salifornia and the Gulf region and elsewhere under glass. (Savannah, Ga.)

77014. -—BAMBUSA SP. From China. Presented by Lingnan University, Canton. Chinese name Koon yam chuk (goddess-of-mercy bamboo). A small, graceful, fern-leaved bamboo 5 to 10 feet high, of clump type, resembling the variety of Bambusa multiplex under P. I. No. 99289 in foliage characters but differing in being less stiffly erect and being perhaps slightly hardier. The leaves are extremely small and closely 2-ranked, on slender branchlets or twigs which curl downward toward the tips in a character-— istic manner. The entire plant is plain green. This handsome little bamboo is one of the hardiest of the clump type and at Savannah, Ga., has withstood temperatures as low as. 15° F.s° It! is commoniy grown as a hedge in southern China and is said to re- Spond admirably to pruning. It is also well suited for growing in individual clumps in the open or for pot culture in the moist atmosphere of the greenhouse. In the dry air and subdued light of living rooms, however, the foliage quickly turns yellow and falls. For trial outside in the South Atlantic and Gulf regions and in the milder parts of the Pacific coast, and under glass elsewhere, (Sayannah, Ga.)

80873. BAMBUSA SP. From China. Presented by the Lingnan University, Canton. Chinese name Fan'taan chuk: A bamboo from the northern and western parts of Kwang tung Province. It is a medium large, thin-walled, semihardy, clump bamboo, used chiefly by the Chinese for making steam—trays for restaurants. It is said to be too brittle for most weaving purposes or for making rope but is extremely ornamental on account of the compact clump habit and the tall straight culms, which are gray with siliceous powder. The culms are naked of branches: to a height of 12 to 15 feet in mature plantings. This bamboo has withstood a minimum temperature of about 17° F. with little injury to the foliage.

from which the new culms arise. It grows to full size only in grove form, in an area at least 30 feet across, and after 10 or more years. Artificial means are required to keep the grove within bounds. Culms 3 years old are useful for fishing poles, plant stakes, etc. The edible shoots, with characteristic smooth, spotted and blotched sheaths, appear in spring. Plants supplied in lots of 5 or more. The

first season the plants should be grown 13 to 2 feet apart in nursery row, in well-— fertilized soil, and be freely watered in dry weather. In the late winter or early spring following, transplant with ball of earth to permanent situation, on good well-

a

drained land, spaced 8 to 10 feet apart each way. Well-rotted manure or a good com— mercial fertilizer should be placed in the hole. New plants from rhizomes left in digging should appear in the nursery in spring and can be transplanted later. For trial from North Carolina to the northern Gulf region and on the Pacific coast. (Savannah, Ga.)

75156. 'PHYLLOSTACHYS FLEXUOSA. Bamboo. From England. Presented by the Director, Royal Botanic Gardens, Kew.

66784. PHYLLOSTACHYS NIGRA. Black bamboo. From China. Collected in a ravine on Peng Mountain, Lungtau Mts., in Kwangtung Province, and presented by Lingnan Uni- versity, Canton. Chinese name Oo chuk. A handsome variety differing from the pre= ceding (P. I. No. 49505) in being more rapid spreading and in that the culms are not quite so tall, that they become solid purplish black in the second year, and in having scemewhat drooping foliage. In China no special use is made of the culms but they can be used for purposes in which much strength is not required. Plants will be furnished in lots of 5 or more. For trial in’ all but the warmest parts of the Southern States and on the Pacific coast. (Savannah, Ga.)

24761. PHYLLOSTACHYS NIGRA HENONIS. From Japan. Originally obtained by Wm. D. Hills, Bureau of Plant Indusiry. The present plants are grown from material received from E. A, McoIlhenny, Avery Island, La. Japanese name Hachiku. A hardy giant bamboo of running habit, vltimately producing culms 50 feet high and 34 inches in diamter. The edible new shoots appear during April and May The shoots are easily dis-—

tinguished from those of other giant bamboos in that the sheaths which at first enfoid' them are unspotted mauve, with a small crinkly green pseudophyll, or blade, at the apex of each sheath. This is considered the hardiest of the giant bamboos but it is more or less injured at temperatures lower than 0° F.: Culture same as for Phyllostachys bambusoides, but in permanent planting the original spacing should be not less than 10 feet. Plants furnished in lots of 15 or more, for growing in grove form only. For irial in the milder parts of the Southern States, except southern Florida, and on the Pacific coast. (Savannah, Ga.)

55713. PHYLLOSTACHYS SP. Bamboo. From China. Collected by F. N. Meyer, Bureau of Plant Industry. A hardy evergreen bamboo of running type, to 25 feet high. This species is easily distinguished from others of similar appearance by the yellowish color of the flattened sides of the internodes of culms and branches during the first year or two, while the rounded parts are green. Grows to full size only in grove form; in an area at least 25 feet across, and after several years. Culms useful for plant stakes, fishing poles, etc. This bamboo was for a time sent out under the name Phyllostachys nevinii but is now considered to be of another, apparently undescribed, species. Its climatic and cultural requirements are the same as for P. bambusoides, (P. I. No. 42659). Plants furnished in lots of 15 or more. For trial in the milder parts of the South, except southern Florida, and on the Pacific coast. (Savannah, Ga.)

A hardy running bamboo, to 25 feet high, with dense foliage. It resembles Phyllostachys aurea but there is never any crowding of the lower internodes of the culm as in that species. The con— ditions under which plants will be furnished to experimenters and the cultural requirements and uses of culms are the same as for P. bambusoides (P. I. No. 42659). (Savannah, Ga.)

89709. PLEIOBLASTUS CHINO (Arundinaria chino). (Poaceae.) Bamboo. Obtained from V. N. Gauntlett & Co., Chiddingfold, England. Variety Laydeker. A dwarf hardy bamboo of running habit, 2} to 3 feet high. The slender culms, usually without branches the first year, bear 10 to 12 lanceolate or linear—lanceolate dark-green leaves and in the second year the branches bear 5 or 6 leaves, mostly toward the tips. The leaves are 2 to 5 inches long, the longer and more slender ones being near the tips, and they are sometimes irregularly mottled with pale green or dull yellow. This bamboo is not very attractive but because of its vigor may be useful as a ground cover where more desirable plants do not thrive. It should be watched for possible development of a weedy habit. Plants will be furnished in lots of 5 or more. For trial in the middle and upper South and on the Pacific coast. (Savannah, Ga.)

52673. PLEIOBLASTUS PUMILUS (Sasa pumila). Bamboo. Presented by Vilmorin, Andrieux & Co., Paris, France.
