bracts: corolla pale yellow, the broad limb only surpassing 

 the bracts: fruit unknown. C. occidental^, Watson, Proc. 

 Am. Acad. xi. 118, not of Gray. 



Guadalupe Island, in the crevices of basaltic cliffs, and also 

 spreading over rocky declivities at lower elevations. The 

 peduncles are often 5-flowered, each bud, even then, folia- 

 ceous-bracted, save that the exterior pair of general bracts 

 always serves as the involucre of the central flower; or, in 

 other words, this one is otherwise bractless. 



Physalis muriculata. 



Less than a foot high, branching, and more or less de- 

 cumbent: root perennial: herbage soft-pubescent and slight- 

 ly viscid: leaves thin, ovate, repand, an inch long, on slen- 

 der petioles of equal length: corolla small, greenish, with 

 darker spots at base: fruiting calyx oval, muriculatc, es- 

 pecially along the prominent, purplish angles. 



Lower California, at Cape San Quentin, May 10, 1885. 



Nicotiana petuniaeflora- 



Two or three feet high, stout, viscid-pubescent and some- 

 what hispid-scabrous: radical leaves oblong-lanceolate, 3 — 4 

 inches long on slender petioles; cauline linear-lanceolate, 

 longer than the radical, on shorter petioles: calyx-teeth tri- 

 angular-lanceolate: corolla an inch and a quarter long, 

 salverform, white changing to bronze-purple; limb three- 

 fourths of an inch broad, with very shallow, scarcely notice- 

 able, rounded, or even refuse lobes. 



Guadalupe Island. Placed under N. Bigelovii, by Mr. 

 Watson (Proc. Am. Acad. xi. 117), and under N. attenuata 

 by Dr. Gray (Syn. Fl. ii. 243), but not properly referable to 

 either, the characters of the handsome, vespertine corolla 

 being quite peculiar, and the hispid pubescence not apper- 

 taining to those species.
