Gnaphalium Chilense Spreng. Cotton-battino- Plant. 



Only occasional, at altitudes less than GOOO ft. (No. 2609.) 



Gnaphalium palustre Mitt. Lowland Cudweed. 



This woolly little composite is gregarious along stream-l)anks 

 in Strawberry and Tahquitz valleys and in damp gravel on the 

 shores of Lake Surprise. (No. 2066.) 



Helenium Bigelovii Orai/. Sneezeweed. 



Near streams throughout the Transition Zone, but by no 

 means common. At the head of Tahquitz Valley, 8700 ft. alt., 

 the large heads form conspicuous yellow patches in the boggy 

 hillside meadows. (Nos. 848, 2467.) 



Helianthus Parishii Grai/. Parish Sunflower. 



Rare along water courses around Strawberry Valley. (No. 

 2612.) 



Hemizonella minima Graij. 



In May this plant is common beneath the pines of the south 

 side at about 5200 ft. alt. It has not been previously reported 

 from Southern California, but was collected by A. J. McClatchie 

 on Wilsons Peak, May, 1896. Perhaps, because of its small size 

 and early flowering period, it has been overlooked. (No. 1802.) 



Hemizonia Wrightii Grai/. Tarweed. 



Collected only twice; the first time at 4400 ft. alt., the second 

 at 5200 ft., both stations being within the pine belt of the south 

 side of the mountain. (Nos. 2420, 2657.) 



Hieracium albiflorum Rool-. Hawkweed. 



The long, straggling stems of this weed are occasionally seen 

 in the upper half of the Transition Zone. (No. 817.) 



Hieracium horridum Fries. 



More common than the last and usually at higher altitudes, 

 reaching into the Canadian Zone at Deer Springs. It was not 

 found except in the cracks of large rocks or in decomposed 

 gTanite at their bases. (Nos. 814, 2560.) 



Hulsea heterochroma Gray. 



Rare, found only on Chalk Hill, and not more than half a 

 dozen plants in all. These viscid, and exhaling a rank, disagree-
