314 Muhlenbergia, Voliinie 2 



ing calyx 4 mm. long, 6 or 7 mm. in fruit, strigose and hispid 

 like the stem, especially the tube, less so on the linear lobes, 

 these I mm. wide: corollas pale yellow, small, barely exserted 

 from the calyx, 5 mm. long, the tube cylindrical, between 3 and 

 4 mm. long, the lobes somewhat ovate, i mm. wide and only a 

 little longer, rounded at apex: stamens equaling the corolla tube: 

 pistil the length of the stamens, the stigma somewhat 3-lobed: 

 nutlets 2 mm. long, ovoid, curved and the back sharply keeled, 

 this dotted with points, as are also the irregular transverse 

 ridges, the intervening spaces with shorter point?. 



The type, in my herbarium, is no. 8470, collected April 27, 

 1907, back of Alum Rock Park, Santa Clara county, California, 

 elevation 1000 feet, on open grassy slopes, not plentiful. What 

 seems to be the same plant is found in the hills west of Los 

 Gaitos. It is one of the forms referred to A. mtermedia^ but may 

 easily be recognized by its small pale flowers. A. intermedia 

 has deep yellow flowers two or three times larger, and since the 

 nutlets were not described, the identity of the plant cannot well 

 be settled until good specimens are obtained from Bodega Bay, 

 the type locality.

 26. 1835. 

 No. 8555, collected May 23, about three miles beyond San 

 Mateo, San Mateo county, on the Half Moon Bay road, elevation 

 200 feet, growing on a moist grassy bank, the exposure north- 

 erly. This has a rather large bright orange corolla, the lobes 

 obovate with folds at the base. The stamens are unequal, three 

 of them inserted at the top of the corolla tube, the othet two 

 about half way up the tube. The pistil extends to the shorter 

 stamens, the stigma capitate. The type was grown from seeds 

 sent from Bodega Bay, Sonoma county.
