lines long. Rio Blanco; July. (152.) — A remarkable species on 

 account of the size of its flowers (opening at night) and the ready 

 dehiscence of the fruit. Schumann (in Fl. Bras. fasc. 98. 132) agrees 

 with Grisebach in the statement that the fruit is indehiscent in all the 

 species of the genus. In the East Indian T. pilosa^ however, it de- 

 hisces as readily as in the present species. 



Prockia crucis, Linn. Barranca. (109.) 



BuNOHOsiA Palmeri. A small tree, 12 feet high, with dense 

 green foliage, the branches glabrous : leaves obloug-obovate, acute, 

 cuneate at base, without glands, glabrous above, loosely pubescent 

 beneath, 4 inches long by 2 wide, on petioles 3 or 4 lines long : 

 racemes 2 or 3 in the axils (distinct or on a very short peduncle) and 

 in a short terminal panicle, 2 or 3 inches long, somewhat appressed- 

 pubescent; pedicels (1 or 2 lines long) jointed at the base: calyx 

 10-glaudular, the broad obtuse lobes glabrous; petals yellow, concave, 



3 or 4 lines long: anthers unappendaged : ovary glabrous, 2-celled, 

 the styles coherent but with the carpels easily separable : fruit 

 unknown. Tequila. (389.) 



BuNCHOSiA (Malacm^a) Guadalajarensis. a small tree, 9 

 to 12 feet high, usually with several stems, the bark gray and scaly, 

 the young branches subtomentose : leaves ovate-elliptical to ovate- or 

 oblong-lanceolate, shortly acuminate, acute at base, the petiole 3 to 5 

 lines long, tomentose beneath, nearly glabrous above, without glands, 



4 or 5 inches long by 2 or 3 broad ; petioles 3 to 5 lines long ; stipules 

 very small and cadui^ous : raceme short-pedunculate, contracted and 

 much shorter than the leaf; pedicels 6 lines long, bibracteate in the 

 middle: calyx lO-glandular, pubescent; petals yellow, 4 lines long: 

 stamens and ovary glabrous ; styles 3, wholly distinct : drupe red, 

 depressed-globose, 3-pyrenous, 6 to 8 lines in diameter. Guadalajara ; 

 September. (490.) — Known as " Manzanito." The wood is white 

 and close-grained. The fruit resembles that of the hawthorn, and 

 yields an indifferent wine. 



Galphimia Humboldtiana, Bartl. (G. glandulosa, HBK. Nov. 

 Gen. & Spec. 5. 172, t. 452, and var. oblongifolia, DC. Prodr. 1. 582, 

 and M09. & Sesse, Calq. Dess. t. 139, with shorter and obtuser leaves.) 

 An upright shrub, 3 or 4 feet high, the short racemes wholly in flower. 

 Rio Blanco, in a deep caiion ; October. (684.) — This was also col- 

 lected by Dr. Lay on Beechey's voyage, 



Galphimia glauca, Cav. A more slender shrub, 4 feet high, with 

 more slender and attenuated racemes, the flowering more prolonged. 

 Barranca. (97.) — The same as 865 Coulter and 13 Hartweg. Much
