 beautiful hybrid palm.] Rev. Hort. 93: 290-291. Fig. 72. 1921.— This beautiful hybrid 

 between Butia capitata var. pulposa Becc. and Arecastrum Romanzoffianum australe Becc. 

 was secured by M. P. Nabonnand some 30 years ago. It scarcely resembles either parent, 

 is of rapid growth, and would probably withstand a temperature of —15° C. — E. J. Kraiis.

 types of lily-of-the-valley, varying in size and form, and in color from white to rose, have 

 been secured by crossing the several existing races. Two years are required for seed germina- 

 tion when grown in pots, and the seedlings bloom about 9 years after the crossing has been 

 accomplished. — E. J. ivraus.

1797. KiNMAN, C. F, Yam culture in Porto Rico. Porto Rico Agric. Exp. Sta. Bui, 27. 

 2S p., 6 pi. 1921. — The yam (Dioscorea spp.), which ranks 2nd among root crops in Porto 

 Rico, and is grown in nearly every family garden, gives certain yields since it is generally 

 free from insect pests and diseases and is adaptable to practically all soil types. Very little 

 attention has been given to improved cultural practices. Highest yields are obtained when 

 plantings are made in ridges of loosened soil bringing the roots above the water line. Plants 

 should be 1-2 feet apart in the ridges depending upon the variety. Either entire roots or 

 portions may be planted, although crown sections give best results. Bordeaux mixture 

 prevents decay of seed pieces. Pruning the vines reduces yields. Supports should always 

 be provided. In experimental work, fertilizers did not give sufficiently increased yields to 

 warrant their use. Of native varieties, Guinea is most satisfactory, giving heavy yields and
