40 THE BROAD-SCLEROPHYLL VEGETATION OF CALIFORNIA. 



Ceanothus sorediatus, Eriodictyon californicum, and Diplacus glu- 

 tinosus, which occur in small numbers in the few openings; also, 

 occasional wanderers from the chaparral; and finally, the young 

 individuals of the dominant trees. The same quadrat includes the 

 following shrubs: 



Rhus diversiloba 59 



Holodiscus discolor 2 



Quercus durata 1 



The herbaceous and ground-shrub vegetation is abundant, both 

 in species and in individuals. The following list is nearly complete, 

 the three most important being numbered in order of abundance: 



Gymnogramme triangularis. Smilacina amplexicaulis. Cynoglossum grande. 



Adiantum jordani. Ranunculus hebecarpus. Micromeria chamissonis (2). 



Aspidium rigidum ar- Dentaria integrifolia. Pedicularis densiflora. 



gutum (1). Saxifraga californica. Galium aparine. 



Melica imperfecta. Tellima heterophylla. Galium californicum. 



Luzula comosa. Potentilla glandulosa. Symphoricarpos racemosus (3). 



Fritillaria lanceolata. Psoralea physodes. Hieracium albiflorum. 



Trillium sessile gigan- Trientalis europsea lati- Achillea millefolium.

Fio. 7. — Quadrat at station 9, 5 meters square. Dominance of 

 comparatively few individuals of Adenostoma. 



At all times of the year this vegetation is in marked contrast to 

 the bareness of the ground beneath the chaparral. In the spring 

 the greenness and luxuriance are especially striking, when such 

 plants as Fritillaria, Trillium, Smilacina, Tellima, and Cynoglossum 

 are conspicuous. Litter is naturally abundant, and the soil is well
