testa showing only a rudimentary lanate condition. The flowers are 

 sulphur-yellow with a brown spot at the base of each petal. This 

 appears to be a true Gossypium, notwithstanding the naked seeds. 

 In mountain ravines near Guaymas. (244.) 



Hermannia pauciflora, Watson. Among rocks in the moun- 

 tains near Guaymas. (227.) 



Melochia tomentosa, Linn. In fences about Guaymas. (148 ) 



Melochia speciosa. Closely resembling M. pyramidata in foli- 

 age and fruit, but more shrubby and branching, less virgate, and finely 

 stellate-pubescent throughout : flowers in loose axillary and terminal 

 cymes, large, rose-color turning purple ; sepals 3 lines long ; petals 8 

 lines long, spreading: capsule finely pubescent, shortly stipitate, re- 

 sembling that of M. pyramidata, but the margins of the cells rounded 

 (not acuminate). — In mountain canons about Guaymas. (650.) 



Waltheria DETONSA, Gray. Guaymas. (251.) 



Ayenia Berlandieri, Watson, var. ? Less pubescent, etc. ; the 

 same as 83 Palmer (1885) from Batopilas. In ravines near Guay- 

 mas. (243.) 



Ayenia filiformis. Annual, erect, the slender stems finely pubes- 

 cent : leaves thin and glabrous or nearly so, from narrowly ovate and 

 obtuse to' narrowly lanceolate and acute, 2h inches long or less, on 

 slender petioles, subtruncate at base, coarsely toothed : pedicels clus- 

 tered or solitary in the axils : sepals narrow, a line long ; petals pur- 

 ple, the blade rhombic, attenuate to the filiform claw, with a deep 

 sinus at the apex embracing the filament, and a filiform dorsal append- 

 age : fruit 2 lines in diameter, beset with numerous slender green 

 processes: seeds surrounded by 2 or 3 stout irregular rugas, the inter- 

 vals more or less pitted. — Resembling and probably including some 

 western forms that have been referred to A. pusilla, but certainly 

 distinct from the typical form of that species as it is found in the West 

 Indies and Brazil. In the shade of rocks high in the mountains about 

 Guaymas. (292.) 



BuNCHOSiA PARViFOLiA. A shrub 3 Or 4 feet high, intricately 

 much branched: leaves sparsely appressed-hairy, round-ovate to ovate- 

 oblong, acute, mostly obtuse at base, glandless, 15 lines long or less, 

 ou very short petioles: racemes few-flowered, pubescent: calyx 10- 

 glandular ; petals pink, 2 lines long : ovary glabrous ; styles nearly 

 distinct : drupe red, 5 to 6 lines in diameter. — On a high rocky peak 

 near Guaymas. (336.)
