22 SEEDS AND PLANTS IMPORTED. 



" Experiments carried on by the United States Department of Agriculture and 

 by State experiment stations in cooperation with this department during the 

 years 1921 and 1922 have established the fact that this clover will survive the 

 winter as far north as Knoxville, Tenn. At this station, as well as several 

 others, the plants from fall seeding made some growth in the fall, held their 

 own during the winter, and made a rapid and heavy growth early in the spring 

 of 1922. This clover made a strong growth on sandy land at McNeill, Miss. ; 

 in this case finely ground bone meal had been used as fertilizer. Preliminary 

 trials have been encouraging, and the department is making further tests."

55708. Pterocakpus sp. Fabaceas. 



Prom Buenos Aires, Argentina. Seeds presented by D t S. Bullock, agri- 

 cultural commissioner, Bureau of Agricultural Economics, United States 

 Department of Agriculture. Received August 17, 1922. 



"(From Cierras de Vilgo, Independencia, Province of La Rioja, Argentina.) 

 Indian name chica, which means ' chew forever ' or ' chew always.' The seeds 

 are eaten toasted by the Indians."' (Bullock.) 



55709. Annoxa diyersifolia Safford. Annonaceae. llama. 



From Tapachula, Chiapas, Mexico. Seeds purchased through R. O. Steven- 

 son. British vice consulate. Received August 19, 1922. 



" The ilama may be termed the cherimoya of the lowlands. The cherimoya 

 does not succeed in the Tropics unless grown at elevations of 4,000 to 6,000 

 feet, where the climate is cool. The ilama, on the other hand, belongs to the 

 lowlands, but is strikingly similar in character to a good cherimoya. It is a 

 valuable recruit and one which can not be too strongly recommended for cul- 

 tivation throughout the Tropics." (Wilson Popenoe.)

55710. Lotus uliginosus Schkuhr. Fabacese. 



From Paris. France. Seeds purchased from Vilmorin-Andrieux & Co. Re- 

 ceived August 19. 1922. 



A pasture plant Of considerable agricultural importance, rather extensively 

 used in New Zealand, from 10 to 15 tons of seed being sown annually. This 

 plant prefers a wet or swampy habitat. It sold in December, 1918, at about 

 a dollar per pound. It is saved for seed mainly in the Auckland Province, 

 but prior to the war the greater portion was imported, mainly from Germany. 

 This seed was exported from the latter country under the name of Lotus 

 villosus or L. uliginosus, which are the European trade names for the L. 

 major of the New Zealand seed trade. L. major is very variable with re- 

 gard to certain characters, such as hairiness, and in consequence several bo- 

 tanical names have been given to the plant. There are apparently a good 

 many different strains, but whether these breed true from seed and are good 

 agricultural species or whether they are due either to the habitat in which 

 they are growing or to fertilization has not yet been ascertained. (Adapted 

 from The New Zealand Journal of Agriculture, vol. 17. p. 347.) 



Received as L. villosus. which is now referred to L. uliginosus.

55711. Prinsepia sinensis Oliver. Amygdalacese. 



From Jamaica Plain, Mass. Seeds presented by Dr. C. S. Sargent, Arnold 

 Arboretum. Received August 25, 1922. 



" Prinsepia sinensis is a species which has been comparatively unknown to 

 horticulturists until recent times. It is quite distinct from the Himalayan 

 P. utilis, which yields a cooking oil common in India, but is closely similar to 

 P. uniflora, which has been introduced by this office several times. Like 

 P. uniflora it is a Chinese ornamental shrub with gray or whitish bark and 

 small gray spines. ■ But while P. uniflora has white flowers, dark-purple fruits, 

 and thick linear-lanceolate leaves, P. sinensis is distinguished by yellow
