gins ; the tube of the corolla is 2 lines long, glabrous, with 

 five glands in its mouth ; the border is 2\ lines in diameter, 

 white, with red nervures, becoming pink when faded; the 

 stamens, half the length of the tube, reach its mouth ; the 

 ovary is 4-grooved, seated on a crenulated disk ; the style is 

 about the same length ; the stigma, double that length, is an- 

 nulated at its base, conical, and simply 2-fid to nearly its 

 middle*. 



Var. auricuJata ; — caulibus erectis, rugosis ; foliis creberrime 

 divaricatis, imbricatim tectis ; ramulis paucis, fuscis, granu- 

 lato-papillosis ; foliis in axillis approximatis circiter 10, 

 longe linearibus, sessilibus, imo latioribus et subauriculatis, 

 marginibus subsinuatis, subrevolutis, supra glabris : pani- 

 culis terminalibus, corymbosis ; stigmate stylo asquilongo, 

 apice 3-dentato. — In Chile : v. s. in herb. Hook. (Lobb, 442). 



A plant with the habit of C. congesta, differing in its more 

 crowded, more divaricated, longer leaves. It is probably a 

 distinct species intermediate between C, congesta and C. si- 

 nuata^ differing extremely from the latter in its habit, its longer, 

 narrower, and more crowded leaves. The leaves (generally 

 eight or ten in each approximated axil) are 1^-2 inches long, 

 1 line broad, quite glabrous above, with subsinuated margins, 

 are minutely puberulous or pulverulent below, when examined 

 under a strong lens ; the peduncle and its branches are pubes- 

 cent ; the acute-lanceolate sepals are pilose on both sides ; the 

 cylindrical tube of the corolla is angular and pilose ; the stigma 

 (rather longer than the style) is somewhat conical, and 3-den- 

 ticulated at its apex. In Bridges's No. 1838, referred by De 

 Candolle to H. myosotifolia^ where I have placed it, the stigma 

 is invariably as I have there described it ; but here it is con- 

 stantly 3-lobed or imperfectly 4-denticulate, as De Candolle 

 mentions. There is probably some confusion in the specimens. 



2. Cockranea corymhosa^ n. sp. ; — valde ramosa ; ramis brun- 

 neis, rugosis ; ramulis longis, adscendentibus, subflexuosis, 

 epidermide rubente laxa rimosa nitente vestitis ; foliis ma- 

 joribus fasciculatis, late lanceolatis, acumine brevi obtu- 

 sulo, in petiolum longum imo dilatatum sensim cuneatis, 

 planis, submembranaceis, tenuissime nervosis, utrinque sub- 

 glabris, rugulosis, versus marginem et in costa subsca- 

 brido-pilosis : paniculis in ramulis terminalibus, corymbosis, 

 glabris ; pedunculo longissimo, compresso, rubente, nitido, 

 superne alternatim et subremote ramoso ; ramulis apice bis
