9. A. pomonensis Jones. Valley Loco. Very similar to A. douglasii; com- 

 monly stout; herbage greener, glabrous or subglabrous; leaves 4 to 6 inches long; 

 leaflets 25 to 35, oblong, 7 to 15 lines long; racemes dense, 1 to 21/2 inches long; 

 flowers spreading or at length more or less deflexed, 5 to 6 lines long; corolla some- 

 times purple-tipped, the calyx I/3 to 1/2 as long; fruiting racemes dense; pods 1 to 

 2 inches long. 



Sandy soil, 10 to 2000 feet : San Luis Obispo and Santa Barbara Cos. near the 

 coast; San Gabriel, San Bernardino and San Jacinto valleys; Conchilla Desert. 

 Mar.-Apr., fr. Apr.-June. 



Note on relationship. — Astragalus pomonensis is about intermediate between A. douglasii 

 Gray and A. vestitus var. menziesii Jones. The appressed pubescence and often spreading flowers 

 point towards A. douglasii ; the congested racemes and usually ultimately reflexed flowers towards 

 A. vestitus var. menziesii. The fruiting calyces may or may not persist on the rachis in either 

 A. pomonensis or A. douglasii.
