Obdbk xxxvii. CALYCANTHE£. 



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

 between it and some Rosacea 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. BUTXERIA, Dm .ffajneJ (Sweet-Scented Shbub). 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 6—12 ft. high: leaves 

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

 1 — 3 in. long; petals and larger sepals linear-spatulate, 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. 



Obdeb xxxviii. SAXIFRAGE/E. 



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-
