TRELHASE \. AM. RHA.MNACH.«. 369 



3. C. FERRUGINOSA, Brongn. — Shrub or small tree at first densely red- 

 tomentose; twigs nearly terete, with fewer lenticels; leaves stout-petioled, 

 somewhat glossy above, i to 4 in. long, elliptical to ovate-lanceolate, 

 obtuse or blunt-pointed, the lower surface with a number of conspicuous 

 scattered (nectar ?) pl'iricls ; cymes dense, becoming somewhat racemose ; 

 fruit 6 to 8 mm. in diameter, more clustered than in our other species. — 

 I.e. (1826)369; Watson, Index, 167. Rhamnus Colubrinus, L., Sp. 2 ed. 

 (1762), 195. — Southern P'lorida and Florida Keys, from the West Indies. 



ADOLPHIA, Mkisn. — Small-leaved or nearly leafless shrubs, with op- 

 posite divaricate green branches articulated with the stem and ending in 

 spines, and small flowers in sparse axillarj' clusters. — Gen. pi. 70; Benth. 

 & Hook. Gen. i. 3S4. — Contains only our species. 



1. A. INFESTA, Meisn . — Mostly puberulent or villous, with often re- 

 flexed short hairs; leaves short-petioled, 2 to 10 mm. long, i-nerved, spar- 

 ingly hairy below, sublanceolate, acute or mucronate, entire or low-ser- 

 rate ; fruit subglobose, crowned with a beak i mm. long, formed by the 

 persistent base of the style. — I.e. (1837); Watson, Proc. Am. Acad. xi. 

 126. and Index, 163. — Arizona and New Mexico, from Mexico. — In 1825, 

 three specific names appear to have been given this plant, viz. : Ceanotkus 

 t'n/estus, HBK. Nov. Gen. vii. 61; ColletiaCi) muliijlora, DC. Prod, 

 ii. 29: and C.(?) disperma, DC. I.e. Adopting the one in general use, 

 the name might be written A. infesta (HBK.) Meisn. 



2. A. Californica, Watson. — Upper branches often more virgate and 

 less spinose; leaves rathtr longer-petioled and more pubescent, spatulate 

 to obovate, mostly mucronate and entire; fruit beakless, the style decidu- 

 ous close to the ovary; otherwise resembling the last. — I.e. (1876), and 

 Index, 460. — Southern California. 



Incomplete specimens of a plant with more virgate, striate branches, 

 not articulated, which have been collected in Arizona {Parish, No. 770), 

 may prove to belong to some southern species of Retanilla or Colletia. 

 Material is much desired. 



GOUANIA, L. — Shrub, climbing by twig-tendrils, with alternate 

 coarsely serrate often 3-nerved leaves, and small polygamo-dioecious flow- 

 ers loosely fascicled along the slender naked ends of the spreading branch- 

 es. — Gen. No. 1157; Benth. & Hook. Gen. i. 385. — About 30 species, 

 largely of tropical America. 



1. G. DoMiNGENsis, L. — -Branches fluted, loosely hairy to glabrate ; 

 leaves short-petioled, i to 3 in. long, becoming glabrous, or persistently 

 hairy along the veins, ovate, narrowly acuminate, subcordate, the blunt 

 teeth commonly ending in cup-shaped (nectar.') glands; inflorescence to- 

 mentose; fruit glabrous, about 6 mm. long and 8 broad (including the 

 wings), notched at top and bottom, when partly grown resembling some- 

 what that of Vaceintum. — Sp. 2 ed. (1763), 1663; Watson, Index, 16S. — 

 Southern Florida and the Keys, West Indies, etc., to Brazil.
