2. Chytraculia Zuzygium (L.) Kuntze. A shrub, or tree 12 m. tall, the bark 

 pale gray, smooth, the branchlets terete. Leaf-blades oval or elliptic, varying to 

 ovate or obovate, 4-6 cm. long, obtuse or abruptly blunt-tipped, glabrous, sessile or 

 nearly so: inflorescence glabrous: hypanthium about 4 mm. wide during anthesis: 

 calyx glabrous 3.5-4 mm. wide: fruits subglobose or spheroidal, 8-10 mm. in 'diameter, 

 glabrous: seeds about 5 mm. long. — 'Di&ers from C . Chytraculia in the glabrous hypan- 

 thium, the sessile or nearly sessile leaf -blades and the mammillate calyx-lid. 



In hammocks, southern peninsular Florida. Also in the West Indies. 



Page 836, extend range of Ludwigia simulata to Florida, 



Page 837, in first line of description of Ludwigia linearis, after "glabrous" add: 

 or puberulent, and extend the range to Texas. 



Page 837, after Ludwigia virgata, insert: 



15a. Ludwigia maiitima Harper. Stem cinereous-puberulent, virgately branched, 

 slightly angled: leaf -blades lanceolate to oblong: corolla yellow 2-2. .5 cm. wide: 

 sepals about twice as long as the hypanthium, reflexed in anthesis, ultimately ascend- 

 ing: style shorter than the sepals: capsules distinctly winged on the angles. — Differs 

 from L. virgata in the larger hypanthium, the shorter and broader sepals and the 

 short style. 



In pine lands, North Carolina to Georgia, Florida and Mississippi. Spring to fall. 



Page 840, after Oenothera laciniata, insert: 



3a. Oenothera moUissima L. Stems branched throughout, the branches ascend- 

 ing or decumbent, softly hirsute: leaf-blades oblong or ovate-oblong to lanceolate or 

 linear-lanceolate, mostly 2-5 cm. long, acute or acuminate, entire or shallowly toothed: 

 flowers axillary: hypanthium 2.5-3 cm. long: corolla yellow, mostly 3-4 cm. broad: 

 capsules cyliudric, 2-2.5 cm. long, copiously pubescent: seeds fully 2 mm. long, 

 nearly smooth. — Differs from 0. laciniata in the soft-pubescent entire or denticulate 

 leaf-blades, the relatively long free portion of the hypanthium and the longer long- 

 tipped seeds. 



In waste places and on shores, about the Mississippi Delta, Mississippi and Louisiana. 

 Naturalized from South America. All year. 



Page 840, after Oenothera heterophylla, insert: 



4a. Oenothera Curtissii (Eose) Small. Stems slender, 1 m. tall or less, spar- 

 ingly appressed-pubeseent : leaf-blades lanceolate to almost linear and entire or ob- 

 scurely toothed, or oblanceolate at the base of the stem and coarsely toothed or pin- 

 natifid, all narrowed at the base: sepals mostly 9-11 mm. long, witu very short free 

 tips, glabrous or with few long hairs: corolla about 3 cm. wide; petals obovate, 

 about 1.5 cm. long: capsules stout-subulate, 12-16 mm. long, decidedly tapering to 

 the apex, curved, appressed-pubeseent : seeds about 1.5 mm. long. — Differs from 0. 

 heterophylla in the small flowers, the short free tips of the sepals and the more taper- 

 ing capsule. [Saimannia Curtissii Eose.] 



In dry or sandy soil, southern Georgia and Florida. Summer and fall. 



Page 847, after Gaura angustifolia, insert: 



5a. Gaura simulans Small. Stem erect, 9-20 dm. tall, the lower part loosely 

 fine-pubescent : leaves copiously pubescent, those of the rosettes and lower part of the 

 stem 8-12 cm. long; blades oblanceolate to narrowly spatulate, pinnatifid: buds 

 glabrous: petals pinkish, 4.5-5 mm. long, the blades oval, longer than the claw: 

 fruit 8^10 mm. long, glabrous, abruptly narrowed at the base. — Differs from G. 

 angustifolia in the glabrous buds and glabrous and broader fruits. 



In pine lands, southern peninsular Florida. All year. 



5b. Gaura Eatonil Small. Stems erect, 1.5-8 dm. tall, often zigzag, glabrous 

 or nearly so, typically simple: eauline leaves rather numerous and quite approximate, 

 erect or ascending; blades linear-spatulate to linear or linear-lanceolate, 3-9 cm. 

 long, or shorter above, remotely denticulate: rachis, and its branches, often zigzag: 

 hypanthium glabrous: sepals linear, about 6 mm. long, obtuse, glabrous: petals 

 white or pinkish, 5-6 mm. long, the blades oval or oblong-oval, twice as long as the 

 claws: larger filaments about 5 mm. long, the anthers fully 1 mm. long: style 

 glabrous: fruit 10-11 mm. long, glabrous, the body oblong-ovate, mostly 4-angled,
