 lanceolate, acuminate, without foliaceous tip or appendages, erect in 

 fruit. At the Petrified Forest in Sonoma Co., also on Mt. Tamalpais. 



3. R. California, Ch. & Schl. Erect, branching, 38 ft. high; 

 prickles few, stout, usually recurved, mostly infrastipular in pairs: foliage 

 deep green, of firm texture, more or less glandular and tomentose; 

 stipules entire: leaflets 57, ovate or oblong, acute or obtuse, the 

 serratures mostly simple, spreading rather than falcate-incurved : corymb

ORDER XXXVII. CALYCANTHE/E. 



A small order, placed here on account of the analogy subsisting 

 between it and some Rosacese in point of floral structure; but probably 

 in no wise related to that order. It is represented in our district by one 

 species of 



1. BUTNERIA, Du Hamel (SWEET-SCENTED SHRUB). Fragrant shrubs 

 with opposite entire exstipulate leaves, and solitary terminal large red 

 or purple flowers. Sepals oo , in many ranks, inserted on a persistent 

 obconical tube; the outer successively shorter and bract-like, the inner 

 longer and colored like the petals; all deciduous. Petals oo, on the 

 mouth of the tube, the inner shorter. Stamens oo , inserted on the upper 

 part of the tube within; filaments short, persistent. Pistils oo , distinct, 

 inserted on the base and sides of the calyx-tube; styles terminal. 

 Achenes enclosed in the dry thin fibro-ligneous calyx-tube. Seed erect; 

 albumen 0; cotyledons foliaceous, convolute. 



1. B. occidentalis (H. & A.), Greene. Shrub 612 ft. high: leaves 

 dark-green, ovate to oblong-lanceolate, scabrous, 3 6 in. long: peduncles 

 1 3 in. long; petals and larger sepals linear-spatulafce, 1 in. long or 

 more; inner petals incurved: sterile filaments linear subulate, densely 

 villous: fruiting calyx ovate, 1^ in. long: achenes villous, 4 lines long. 

 Common along streams in the lower mountains. Flowers of a dull 

 dark red. May August. 



ORDER XXXVIII. SAXIFRAGES. 



Herbs or undershrubs (Ribes shrubby) with simple alternate usually 

 exstipulate leaves, the petiole often stipulaceously dilated at base. 

 Stems mostly simple below, commonly leafless and scape-like. Inflores- 

 cence mostly either cymose, racemose or paniculate. Calyx of about 5 

 sepals, often more or less coherent below and united to the base of the 

 ovary. Petals as many or 0. Stamens 5 or 10, perigynous or hypogy-
