8 mm. long; style deciduous near the base. — Prodr. (1825), ii. 22; Wat- 

 son, Index, 163. Rhamnus volubtlis^ L. f. (1781), 152, Jide DC. R. scan- 

 dens, Hill, Veg. Syst. (1769), xiv. 64. — Virginia to Florida and Texas, 

 climbing over trees to a great height. — The specific name of Hill appears to 

 antedate that employed here and now in general use. Some authors 

 would, therefore, write B. scandens (Hill). 



KARWINSKIA, Zucc. — Unarmed shrub, with mostly opposite pin- 

 natelj veined leaves, and small flowers in short peduncled axillary clus- 

 ters. — Denkschr. Baier. Akad. iv. 349; Benth ix. Hook. i. 377. 



I. K. HuMBOLDTiANA, Zucc. — Twigs morc or less puberuleni and 

 pruinose; leaves inconspicuously pellucid-punctate and sometimes dark- 

 dotted, mostly glabrate, slender-petioled, i to 3 in. long, elliptical-ovate, 

 obtuse to acute or mucronate, rounded or subcordate at base, entire or 

 undulate, the conspicuous mostly simple veins ending in a marginal 

 nerve; peduncle 2 mm. or less long, few-flowered; pedicels of about the 

 same length, both elongating in fruit; drupe ovoid, apiculale, half-inch 

 long; style articulated near the top. — Miinchen. Abhandl. (1832), i. 353; 

 Watson, Index, 168. — Mexico and Lower California, extending into Texas 

 and New Mexico. 



REYNOSIA, Griseb. — Unarmed shrubs or small trees, with mostly 

 opposite pinnately veined, very thick and coriaceous evergreen leaves, and 

 small flowers in sessile axillary umbels. — Cat. PI. Cubens. 33; Eggers, 

 Vidensk. Meddelelser, Copenhagen, 1877, 173, pi. 2. 



I. R. LATIFOLIA, Griseb. — Small tree; twigs glabrous or at first slight- 

 ly puberulent; leaves half-inch to inch and a half long, on short thick 

 petioles, elliptical to spatulate-oblong or obovate, rounded at both ends, 

 emarginate and commonly short-mucronate, entire, with revolute mar- 

 gins; flowers appearing with the new leaves; pedicels about 4 mm. long, 

 increasing to 8 mm.; fruit elliptical, half-inch long, short beaked. — I.e. 

 (1866) 34; Gray, Bot. Gaz. iv. 208; Chapman, Suppl. 612; Sargent, For- 

 est Trees, 39. Rhamnidiutn revolutum, Chapm., Suppl. 612 (and in part 

 of Eggers' distributions).- — Southern Florida and Florida Keys, from the 

 West Indies. — The leaves of the Cuban type rather shorter, thicker, and 

 more bronzed, than in our plant. 



I was unable to find Vahl's type oi Rhamnus Icevigatus (Symb. iii. 41) 

 at Copenhagen, and the evidence that it was this plant seems too slight 

 for even the most ardent reformer of nomenclature to yet venture on re- 

 storing Vahl's specific name. 



Rhamnidium revolutum, Gr., of the West Indies, which resembles 

 this species very closely in foliage characters, has petals, and the albumen 

 is not ruminated.
