Trifolium Traskae sp. nov. 
An erect villous annual 6 to 8 inches high, branched from 
- the base, with few leaves, long internodes, pedunculate heads of 
dark purple flowers, and narrow dentate leaflets attenuate at 
both ends. 
This species was collected by myself on Santa Catalina 
island, California, April 21, 1907, and does not seem to be in 
the other herbaria that I have examined. On taking the ma- 
tine gardens launch to Moonestone bay, it was gathered in rather 
dry situations about 100 feet from the shore. More time for 
investigating the region might have proven that it was more or 
less common on that and other portions of the island. 
Annual with erect branches froin the base, about adm. high, 
villous throughout, internodes long, 5 to 10ocm.: lower leaflets 
rem. long, 3mm. wide, elliptical, acute at both ends, margins
