APPENDIX 1337 



to lanceolate or linear-lanceolate near the inflorescence, sessile and half-clasping, 

 bright green, the lower surface and the margins sparsely pubescent with both simple 

 and forked hairs: racemes becoming 3 or 4 dm. long: pedicels ascending, glabrous, 

 becoming 1 cm. long: sepals ovate, 4 mm. long, acute, narrowly scarious-margined : 

 petals 9-10 mm. long, white, obtuse: style 1 mm. long: pods linear-filiform, flattened, 

 6-7 mm. long, about 1 mm. wide, erect or nearly so. the valves 1-nerved: seeds nar- 

 rowly winged, in 1 row. — Differs from A. patens in the longer pods and the glabrous, 

 upper surface of the leaves and the upper part of the stem, and from A. hirsuta in 

 its larger corolla, evident style and longer pods. 



On shaded banks, western Georgia and central Alabama. Spring. 



Page 487, after Warea cuneifolia, insert: 



la. Warea Cdrteii Small. Plants bright green. Stems 4-15 dm. tall, simple 

 or widely branched: leaf -blades linear or sometimes cuneate on the lower part of the 

 stem, 1.5-3.5 cm. long: racemes many-flowered: sepals nearly linear or somewhat 

 spatulate, 4.5-5.5 mm. long: petals white or nearly so, 6-8 mm. long, the claws 

 prominently sharp-toothed: pods curved, 5-6 cm. long. — Differs from W. cuneifolia in 

 the suborbicular or ovate petal-blades and the longer pods. 



In pine lands, peninsular Florida. 



Page 494, in second division of the key to Bosales, after ' ' perianth present, ' ' add 

 "except in Liquidambar." 



Page 513, after Opitlaster stellatus, insert: 



la. Opulaster Alabam^nsis Eydb. A shrub, branches stellate especially when 

 young. Leaf -blades broadly ovate, 2-5 cm. long, obtuse or acute at the apex, often 

 indistinctly 3-lobed, doubly crenate, stellate-pubescent, at least beneath, acute or 

 rounded at the base : inflorescence densely stellate : follicles 3-5, permanently stellate, 

 about 8 mm. long. — Differs from O. stellatus in the larger carpels and the narrower, 

 acuminate and sparingly pubescent leaf -blades of the sterile shoots. 



In dry soil, Alabama and South Carolina. Spring. 



Page 513, after Opulaster opulifoUus, add: 



4. Opulaster austr^lis Eydb. A shrub with glabrous angled branches. Leaf- 

 blades broadly ovate, 4-8 cm. long, acute, deeply 3-lobed and doubly toothed, rounded 

 or truncate at the base: corymbs dense: hypanthium stellate: follicles usually 5, 

 glabrous, 3-6 mm. long, acute. — Differs from 0. opulifoUus in smaller folicles and 

 the seed with its small nearly terminal caruncle. 



On dry or stony mountam sides, Virginia to South Carolina. Spring. 



Page 514, after Spiraea salicifolia, insert: 



la. Spiraea subcan^scens Eydb. A shrub somewhat resembling S. tomentosa 

 in habit, but with the stem and branches less densely pubescent. Leaf -blades thinnish, 

 but firm, lanceolate to elliptic-lanceolate, acute at both ends, sharply and finely ser- 

 rate, slightly pubescent above, tomentulose beneath, and only slightly paler than 

 above: sepals ciliate: petals pink, suborbicular, about 2 mm. wide: follicles glabrous, 

 about 2 mm. long. — Differs from >Si. salicifolia in the tomentulose finely serrate leaf- 

 blades, the dense inflorescence, the canescent hypanthium and the reflexed sepals. 



In woods, near Anderson, South Carolina. 



Page 514, strike out the description of Arunciis Aruncus, and insert: 



Style short, much shorter than the carpel-body during anthesis: follicle-bodies narrowly oblong 



about 3 mm. long. 1. A. Aruncus. 



Style long, about as long as the carpel-body during anthesis: follicle-bodies 

 turgid, oval or ovoid, about 2 mm. long. 

 Mature carpel-bodies ovoid, sometimes apparently oblong when dry, the 



beaks mostly spreading: leaflets decidedly pubescent beneath. 2. A. pubescens. 



Mature carpel-bodies oval, sometimes apparently ovoid when dry, the 



beaks mostly erect: leaflets glabrous or nearly so. 3. A. Allegheniensis. 



1. Aruncus Ardncus (L.) Karst. Plants 2 m. tall or less, glabrous or nearly 

 so up to the inflorescence at maturity: leaflets ovate, 2-7 cm. long, acuminate, doubly 

 serrate, glabrous, smooth and shiny or with scattered hairs especially when young: 

 sepals of the pistillate flowers lanceolate or triangular-lanceolate, acuminate: petals 

 of the staminate flowers scarcely 1.5 mm. long, narrowed at the base: follicles nar- 

 rowly oblong, about 3 mm. long, less than 1 mm. thick, slightly beaked. 



In thickets and waste places, locally naturalized from Europe in the eastern United 

 States. Spring and summer.
