62 CALIFORNIAN FIELD NOTES. 



The spring annuals had here almost disappeared; only 

 occasional remnants of Gilia and CEnoihera were found in 

 bloom among the withered remains of Olyptopleiira setulosa^ 

 Castilleia plagioiomia, and other characteristic desert plants. 

 In the shade of the sycamores and willows which here 

 clothed the banks of the stream Epipactis gigantea was 

 flowering profusely, and Glycyrrhiza glutinosa, a rare plant 

 with us, was locally abundant on a sloping bank. Ascending 

 the valley the willows become less abundant, the stream re- 

 appears in volume, and the sandy levels that flank its bank 

 are abundantly clothed with what looks like Juniper, but on 

 investigation proves to be mostly Kunzia glandulosa^ which 

 seems to occupy a narrow belt at this elevation all the way 

 across the desert rim from Harold to the Cajon Pass, Here 

 for the first time I found Amygdalus fasciculata. It grew 

 in dense thickets, and bore little fruit, but was covered with 

 tent caterpillars. Among the desert shrubs Tetradymia 

 spinosa, T. glahraia, T. comosa and Salvia carnosa were the 

 most conspicuous. Scattered over the mesa were numerous 

 plants of OpunUa echinocarpa with occasionally O. basilaris, 

 and a few shrubs of what seemed the typical Ceanothiis ves- 

 iiiitSy Greene. Eriogonums were numerous; E, Heermanni 

 and E. Palmeri were coming into flower on the higher 



grounds, while in the river wash E. molesiiim and E. pus- 

 ilium were in full bloom. 



In the marshy ground at the river edge magnificent speci- 

 mens of Castilleia linaricefolia abounded, and on the drier 



Nicotiana 



ijlorus, Calocliortns Kennedy 



longistylis. A mile or so 



further up on the exposed slope of the river bank I gathered 

 a dozen specimens of what seemed a variety of CEnoihera 

 gaurcBJloray but which on examination and comparison proves 

 to be new. I shall therefore characterize it as 



. (Enothera rutila. Annual, stoutish, erect, 6 to 8 inches 

 high, glabrous except the younger leaves and the inflores- 

 cence which are sparingly pubescent; leaves ovate-lanceolate, 

 narrowed to the petiole, remotely denticulate in the upper
