cymes axillary and terminal, crowded, on very short peduncles ; invo- 

 lucre campanulate, the obovate lobes lacerate at the summit; glands 

 5, rounded and transversely plicate, the inner fold often smaller ; ap- 

 pendages rounded, twice larger than the gland, entire, white : capsule 

 glabrous, 2 lines long : seed irregularly tuberculate. — Hacienda San 

 Miguel (181, 246). 



Euphorbia (Cyttarospermum) subreniforme. Annual, very 

 slender, erect, the stem and branches glabrous, a foot high or less : 

 leaves all opposite, on filiform petioles exceeding the thin blade, which 

 is subreniform, rounded-truncate and slightly apiculate or emarginate 

 at summit, shortly cuneate at base, sparingly villous and ciliate, the 

 largest 6 lines broad: involucres solitary, very small (| line long), 

 villous ; lobes entire or nearly so, ciliate ; glands 4, purple, stipitate, 

 rounded, with an appendage of 3 or 4 long purple seta3 : styles purple, 

 2-parted ; capsule villous, § line long : seeds oblong-ovate, the shallow 

 pits tuberculate-margined and punctate in the centre. — Hacienda San 

 Jose (60), and Frayles (292). 



Jatropha cordata, Muell. Arg. — Norogachi (CC); known as 

 " Matamuchachos." The bruised leaves are applied to sores, and 

 added to the water in which children are bathed, to impart vigor. 



Croton fragilis, Muell. Arg., var. sericeus, Muell. Arg.? 

 Fruiting specimens, shrubby, 4 feet high : capsules rather acutely 

 lobed, canescent with short somewhat scattered stellate pubescence : 

 seeds smooth, lead-colored, 3 lines long. — Hacienda San Miguel (14). 



Croton ? Pistillate specimens only, closely resembling C. 



gracilis, but the styles very short and stout, and the broadly ovate 

 seed much broader. — Frayles (288). 



Croton (Eucroton) tenuilobus. Monoecious ; suffrutescent, 

 much branched, the slender branches and petioles closely appressed- 

 scurfy, the scales stellately parted to a disk-like centre : stipules obso- 

 lete ; leaves linear-lanceolate, acute, obtuse and eglandular at base, 

 lepidote beneath, greener above and rough with fine stellate pid)es- 

 cence, 1 to 2\ inches long; petiole 2 or 3 lines long: racemes short 

 and shortly pedunculate : male flowers decandrous ; pistillate flowers 

 several, scattered, usually becoming reflexed and secund, on pedicels 2 

 lines long ; calyx-lobes distinct, very narrow, lepidote, ^ to 1 line long, 

 somewhat unequal: styles divided; capsule stellate-tomentose : seed 

 oblong-ellipsoidal, obscurely reticulated, 1 1 lines long. — Of Mueller's 

 series Argyrocroton, as defined in Fl. Brasil., peculiar in appearance, 

 and the pistillate flowers with characteristic calyx. Hacienda San 

 Jose (29).
