1. integrifdlia, Benth. & Hook. Shrub, 2-8 ft. high: 

 Ivs. oval, entire, or occasionally long-petioled, with 3 

 Ifts. : panicles and new growths puberulent: fls. white 

 or rose-colored : fr. very large. California. S.S. 3:109. 

 —An evergreen species. 



cc. Lvs. pubescent beneath

2. ovita, Watson. Another Californian species re- 

 sembling the last, but with larger and smoother leaves. 



3. Cdtinns, Linn. Smoke Bush. Venice Sumach. A 

 bush 10-12 ft. high, with simple obovate lvs. and brown

2116. Young plants of Rhus typhina. \ 



color of its inflorescence.— This species used to be com- 

 mon in cultivation, liut it does not seem to reproduce 

 itself as readily as some species, and in many cases 

 when killed by borers or other causes, it has not been 

 replaced. Gng. 5:118. Gn. 34, p. 162; 54, p. 505. 



4. cotinoides, Nutt. A small tree, 20-40 ft. high: lvs. 

 undivided, oval or obovate, smooth, thin: fls. greenish 

 yellow, in large panicles: pediocN lirr.,iiiin!,' I'himose as 

 they develop. Flowers in spriiiL.'. :iiiil tli. foliage as- 

 sumes most brilliant autumn tini^. M i^-i-sippi valley. 

 S.S. 3:98-9.— Known also as Cotn.ns A ,„. rimnns, Nutt. 

 Sometimes called "Chittam-wood." 



5. Canadensis, Marsh. (B. aromdtica, AXt.). Spread- 

 ing shrub, 3-8 ft. high, with 3-foliate, crenate, pu- 

 bescent, petiolate, aromatic lvs. : fls. yellow, small, in 

 clusters or short spikes, either axillary or sometimes 

 terminal: fr. globular, coral-red, sparsely hairy, and 

 comparatively large. Flowers in spring before the lvs. 

 appear. Rocky woods, eastern N. Amer. Var. trilobata 

 has the Ifts. deeply cut or 3-lobed. — This is one of our 

 best cover plants or under-shrubs and spreads naturally 

 by layers. Will flourish in any soil and is especially 

 adapted to dry, rocky banks. 



6. Toxicodendron, Linn. Poison Oak. Poison Ivy 

 A scandent or climbing plant: lvs. smooth or often 

 pubescent on veins, ovate, sinuate, or lobed, petiolate- 

 panicles short-stalked: fr. ribbed when dry. June. N 

 Amer. V. 10:103. — Care should be taken in planting 

 this species, as it is very poisonous to many, and for 

 this reason it should be extirpated from our ornamental 

 plantations, rather than added to them. The autumn 

 color is attractive. As here understood, it includes B. 

 radicans, Linn. 



7. diversiloha, Torr. & Gray. A Californian species 

 closely allied to the preceding, equally poisonous, and 

 therefore not to be recommended for plaiting. 



8. glabra, Linn. Smooth Sumach. Fig. 2115. Smooth, 

 glaucous, 10-15 ft. high: Ifts. many, green above, white 

 beneath, narrowly oblong, with serrated edges: fls. in 

 terminal panicles : fr. crimson, hairy. July. N. Amer.— 

 One of the best species for mass or other planting. Var. 

 laciniata, Carr., has the Ifts. deeply cut, giving the lvs. 

 a very fern-like appearance. Like the type, it colors in 

 autumn. R.H. 1863, p. 7. V. 10:101. 



9. venenata, DC. Dogwood. Poison StraiACH. Usu- 

 ally taking the form of a tree, 10-20 ft. high : Ifts. 7-13 

 on a red petiole and midrib, smooth, shining green 

 above, pale beneath: fls. in a narrow panicle, drooping: 

 fr. small, flattened, white. June. Jloist ground, eastern 

 N. Amer. -One of the most beautiful, but unfortunately
