Plants recently introduced, not yet available for distribution. 
agave 8p. (Amaryllidaceae) , 60225. From Algiers, Algeria. Presented by 
Dr. L. Trabut, through Prof. L. H. Dewey, Botanist in Charge of Fiber Investi- 
gations, who says: 
"These are seeds of an Agave hybrid sent to me by Doctor Trabut. They are 
the result of a cross made by him about 1908, in which the staminate parent was 
the sisal, Agave sisalina, and the pistillate parent an undetermined species which 
he had received from San Luis Potosi, Mexico. The object in making the cross 
was to obtain a plant more resistant to cold than Bisal, yet having thin straight 
leaves producing fiber similar to that of the last named species. Some of the 
seedlings resulting from this cross have been developed further by selection, 
but up to the present, none of them has attained commercial importance in Algeria. 
"The Department will test this hybrid on the Island of Porto Rico, where 
its value, in comparison with that of other producing agaves, will be ascer- 
tained." 
crotalaria spp. (Fabaceae), 60301 to 60303. From Salisbury, Rhodesia, 
Africa. Seeds presented by H. G. Mundy, chief agriculturist, Department of 
Agriculture. 
Knowing the desire of this Department to test leguminous plants valuable 
as green manures and cover crops, Mr. Mundy has sent in three Crotalarias which 
seem likely to prove of interest. This genus contains about 300 species, dis- 
tributed throughout the Tropics of both hemispheres; only a small proportion of 
them have yet been tested as cover crops in the United States. In the Asiatic 
Tropics, and in Africa, various species are being used successfully for this 
purpose. 
60301. crotalaria intermedia. "Plant 2 to 3 feet high, branching less than 
6 inches above ground; leaflets long and narrow. Flowers creamy yellow with 
purple veins. Matures in four months." (Mundy). 
60302. crotalaria M axillaris. "Plants 1 1/2 to 2 1/2 feet high; branching 
along entire main stem; leaflets broad. Flowers bright yellow. Matures in 
four months." (Mundy). ' 
60303. crotalaria sphaerocarpa. "Plant 1 to 1 1/2 feet high, of bushy habit. 
Flowers yellow. Matures in 3 1/2 months." (Mundy). 
esenbeckia LEiocARPA (Rutaceae), 60201. From Brazil. Presented by F. L. 
Rhodes, American Telephone and Telegraph Co., New York, N. Y. 
Our attention was first directed to this species by Mr. Rhodes, who received 
from southern Brazil, a shipment of seeds together with information to the effect 
that the tree might prove particularly suitable for telephone poles, because of 
its usually branchless, straight trunk. On being informed that we had not tested 
the species in this country, he generously divided the seeds with us. 
Esenbeekia leioearpa, related to the citrus fruits, is described as an erect, 
medium-sized tree from the forests of southeastern Brazil, where the slear yellow
