I. Cuscuta Californica; pedunculis unifloris solitariis, sub flore dilatato-infundibuli- 

 formi, calycis lobis acutis corolla multo brevioribus, corolla? tenui-membranaceas tubo 

 brevi, laciniis lanceolato-subulatis elongatis, squamis millis, staminibus quinque fauci 

 corollas insertis laciniis dimidio brevioribus, stylis duobus, stigmatibus capitatis.

1. Wigandia? Californica; fruticosagummifera, foliis elliptico-lanceolatis in petiolum 

 brevem attenuatis coriaceis integerrimis supra glabris subtus reticulatis in areolis albo- 

 canescentibus, staminibus inclusis. (Tab. LXXXVIII.) 



Different as the present plant appears, at first sight, from the Wigandia Caracasana figured in the Bot. 

 Register, tab. 1966, yet the inflorescence and the structure of the flowers are so similar, that without mature 

 fruit we dare not venture to separate it. It is quite shrubby, the glabrous stem exuding a gum-resin. Leaves 

 3-4 inches or more long, alternate, coriaceous, elliptical-lanceolate, tapering gradually into a short petiole, 

 quite entire, above glabrous, rather indistinctly reticulated with depressed veins ; below strongly reticulated 

 with prominent veins, which are rendered more conspicuous by the areolae being filled with very short 

 whitish down. In two or three of the upper leaves, and at the apex of the branch, the small flowers, (scarcely 

 more than half an inch long) are collected into dense capitate circinnate racemes. Corolla infundibuliform, 

 thrice as long as the deeply divided linear-oblong calyx-segments. Stamens included. Filaments unequal, 

 inserted below the middle of the tube, and then decurrent to the base of the tube ; the decurrent portion 

 alone slightly hairy. Anthers of two oval cells, not mucronate. Ovary ovate, slightly hairy, with no evi- 

 dent hypogynous disk, 1-celled, with two opposite parietal placentas ('*;), resembling two T's, to the free edges 

 of which several ovules are attached, exactly as in W. Caracasana (see Dr Lindley's excellent figure above 

 quoted.) Styles 2, nearly as long as the filaments. Stigmas capitate, depressed at the top.
