THUNBERaA grandiflora (Acanthaceae) , 57216. From St. Clair, Trin- 
idad, British West Indies. Plants presented by R. T. Williams, super- 
intendent, Royal Botanic Gardens. Var. "alba." 
"The typical form of Thunbergia grandiflora is well known in tropical 
gardens, where it is highly esteemed for its large, sky-blue flowers 
and the ornamental effect of its foliage. The white form (var. "alba') 
is less widely cultivated, though perhaps as meritorious as the type. 
It is a strong-growing climber, useful for covering pergolas and fen- 
ces, and is sufficiently frost-resistant for cultivation in the warmer 
parts of Florida and the most favored sections of southern California."

TRIFOUUM PRATENSE (Fabaceae) , 57036. Red clover. From Copenhagen, 
Denmark. Seeds presented by H. N. Knudsen, Danish Royal Agricultural 
Society. "Tystofte No. 40" originated in a 2-year plat of "Rosendal" 
clover. Seeds of this variety were sown in 1900, and the clover was 
thus subjected to the hard winter of 1901. In 1902 the strongest 
plants from this test were selected; one was No. 40. Later this strain 
was compared with others in several tests. In 3 or 4 tests, all the 
clovers made vigorous growth during the first year, and in this respect 
No. 40 averaged well above the others. In all four tests No. 40 gave 
the largest crop, fully 20 per cent better than that of the next best. 
These results agree well with the results of earlier tests at Lyngby 
and Tystofte in which this strain decidedly surpassed all others.

vitis sp. (Vitaceae), 57218. Grape. From Huatusco, Vera Cruz, 
Mexico. Seeds presented by Dr. C. A. Purpus. "This was collected on 
very dry, rocky mountain slopes near Jalisco in Chiapas. The vine 
bore enormous bunches of red grapes and was in flower at the same time; 
it had no leaves. The fruits were partly ripe at the end of April 
and in May, and I believe would make excellent jelly." (Purpus.)

amy gd alus persica (Amygdalaceae) , 43133. Peach. "Muir's Perfec- 
tion." From Avondale, Auckland, New Zealand. "The tree which was sent 
to me in 1921 has matured a very good crop of fruit this year. The 
peach is medium sized, of very high color, and has a very agreeable 
acid flavor." (John B. Wiggin, Holly Hill, S. C, July 20, 1923.)
