NEW OR LITTLE-KNOWN PLANTS OF SOUTHERN 

 CALIFORNIA.— I. 



By S. B. Parish. 



Selaginella Bigelovii Underwood, Bull. Ton*. Club, xxv. 

 130. This is the common Selaginella of the intra-montane region 

 of Southern California, abundant on dry soil, usually in the shelter 

 of shrubs or stones, or on shaded banks, throughout the hill region, 

 and ascending the mountains to 7,000 ft. alt. The prostrate Selagi- 

 nella (1,200, Parish) noted by Dr. Underwood (1. c. 133), is a 

 plant of the lower altitudes of the desert region. It occurs on the 

 bases of boulders at Palm Springs and Whitewater, at 500-1,200 

 ft. alt. A third form was observed last June at Toy's Ranch, in 

 Sycamore Canon, near Poway, San Diego County. This has 

 slender, thread-like stems, creeping on hard clay banks. It is 

 very distinct in appearance^ and can hardly be placed in any of 

 the species of Dr. Underwood's revision. Unfortunately it was 

 so dry and brittle, that no specimens were secured, and it is men- 

 tioned to direct the attention of other collectors to it. 



Sparganium simplex angustifolium Engelm; Gray, Man. 

 5th ed. 481. Bluff Lake, at 7,400 ft. alt., in the San Bernardino 

 Mountains, Miss Nora Pettibone. 



Potamogeton lucens Linn. Sp. PI. 126. In pools in the 

 dry bed of Penasquitas Creek, San Diego County, June, 1897. 



Monerma subulata Beauv. Abundant above high-water 

 mark, around the borders of the first laguna south of Oceanside, 

 and sparingly by a desiccated pool on the neighboring mesa, June, 

 1897. Known heretofore from the Mediterranean, South Africa 

 and Australia. The plant was identified by Dr. Beal. 



Avena barbata Linn. Although it is only within recent 

 years* that this species has been reported from California.it has 

 evidently been established, at least in the southern counties, from 

 very early times, but has been confused with A. fatua, and it is 



* First by Vasey, Descrip. Cat. Grasses U. S. 56 (1885). See also 

 Dewey, Eryth. v. 29; McClatchie, Eryth. ii. 78. 



Erythea, Vol. VI, No. 9 [22 September, 1898].
