1. A. alnifolia, Nutt. A shrub, 3 to H feet high, glabrous throughout or often 

 more or less woolly-pubescent: leaves broadly ovate or rounded, occasionally oblong- 

 ovate, obtuse at both ends or rarely acute, often somewhat cordate at base, serrate 

 usually only toward the summit, i to 1 i inclies long : racemes short : calyx usually 

 tomentose within: petals 3 to 12 lines long, narrowly oblong: fruit mostly o or 4 

 lines in diameter. — Aronia alnifolia, Nutt. IJenera, i. 3()G. Aindanchier floriJa,

On mountain-sides throughout the State, from near the level of the sea to an altitude of 10,000 

 feet in the Sierra Nevada. It ranges northward to British Columbia and eastward to the Koeky 

 Mountains, varying much with the character of the locality in which it is found. 



28. CANOTIA, Torrey. 

 Calyx small, camijanulate, ch^cply ^-clell, persistent, imbricate iu the bud. I'etals 

 f), obhuig. ytamens 0, hypogynous; liluments attenuate-bubulalo, persistent. Ovary 

 superior, 5-celled : styles united, stout, persistent : stigma terminal : ovules several, 

 amphitropous, attached to the central angle. Capsule woody, oblong, attenuate 

 into the persistent style, septioidally 5-valved, the valves 2-cleft. Seed solitary, 

 attached by the middle, oblong, compressed, produced below into a membranaceous 

 wing. Embryo surrounded by fleshy albumen ; cotyledons broad ; radicle inferior. 

 — A leafless shrub or snudl tree, with straight spinose branches, and smooth green 

 bark ; flowers white, in small lateral cymes. 



A genus of a single species, very anomalous in its characters, and here appended to the Rusaccm 

 (with which it has little in common) only because it is so referred by Bentham & Hooker. 



1. C. holacantha, Torr. Often 10 to 20 feet high, much branched; the light 

 green striate surface of the branchhits marked by scattered small dark scars from 

 which small scale-like leaves a[)pear to have fallen : cymes few-llowered, bracteato 

 with small thick triangular bracts : calyx very small : petals 2 lines long, e(pialling 

 the stamens ami i)istil : capsule 9 to 12 lines long, dehi.scent to the miildle : seeds 

 half as long, including the wing, which is as long as the dark linely tuberculate 

 body. — Pacif K. lfei». iv. G8.

OiiDEii XXXIII. CALYCANTHACE^. 



Aromatic shrubs, with opposite entire leaves (not punctati'), no stipules, sei)als, 



])etals and stameus indeliiiite, as it were pa.ssing iuto each other, and all coalesctcnt 



below into a closed cup which is lined by a hollow recisptacle or disk, bearing 



numerous simple pistils (becoming akeiies) in the manner of the Kose : the anthers 



adnate and extrorse : cotyledons foliaceous and convolute. 



Consists of the United States genus Calycanlhus, and the .Japanese genus of a single species, 

 Chlmonanthus ; jirobably most allied to the apetalous order Mmiiiniacecc, of the southern hemi- 

 sphere,but generally ranked ne.xt to Romccce ; by Bentham and Hooker placed next to Maiiitoliaceiv, 

 and the cup taken to be wholly receptacle or torus. But the same interpretation is now commonly
