44103. Helianthtjs axgustifoeii s L. Asteracese. Sunflower. 

 Grown at the Plant Introduction Field Station, Chico, Calif., from seed 



collected by Dr. David Griffiths. Numbered February 13, 1917. 



-This native sunflower is said to occur from New Jersey to Florida and 

 westward to Texas. It attracted the collector's atcention in a native condition 

 on the prairies of Arkansas, where it grows most luxuriantly. There are sev- 

 eral characteristics which adapt it to ornamental uses: The general habit of 

 the plant is pleasing; it has a small flower with long, graceful rays; the foliage 

 is narrow, long, drooping, and glossy : the main steam and each of its branches 

 are long, graceful peduncles; but. best of all, it will cut and come up again 

 and is perennial in habit. These characteristics make this plant valuable for 

 tall massing effects, like the cosmos, as well as for cutting purposes. The 

 seed distributed this season is from a single variety of this very variable and 

 widely distributed species. Many other forms exist, and doubtless n the 

 hands of horticulturists it will be found capable of much improvement. Some 

 of its varieties are bushy, and all can he pinched back to a bushy form."

 25 feet." (Hawaii Agricultural Experiment Station Bulletin No. 25, p. '/3.) 



"Moanalua, the round variety. This is not an easy thing to bud, and all the 

 plants we have have been inarched. A good avocado, one of our best, it is a 

 late variety, however, and on that account might not be as suitable for the 

 climate of Florida as some of the early kinds." (Maclntyre.) 



44105 to 44107. Trifolium pratexse L. Fabacea?. Red clover. 

 From Denmark. Presented by Mr. H. Hertel, Danish Royal Agricultural 

 Society. Copenhagen. Received February 8, 1917. 



44105. " Tystofte No. 71. an early red clover. Furnished by the experi- 

 mental station at Tystofte, near Tjaereby on Seal and. The seed rais- 

 ing of early red clover in general is. at the present time, sparse here in 

 Denmark, where favorable conditions for the fecundations are lacking.

44106. " Tystofte No. 87. a late clover. Furnished by the experimental 

 stat on at Tystofte. near Tjaereby on Sealand. This is a new form. 

 obtainable so far only in small quantities.
