than the leaves ; pedicels glanduliferous, stout and 2 or 3 lines long 

 in fruit: ovary pubescent, globose, beaked by the subpersistent style; 

 fruit 2-3-lobed, the seeds 4 lines in diameter. — In Tamasopo Canon, 

 San Luis Potosi ; July, 1890 (n. 3540). Near B. lanceolata of Turcz- 

 aninovv. 



Sargentia (?) Pringlei. a shrub, 10 to 15 feet high: leaves 

 coriaceous, pinnately 1-foliolate or sometimes palmately 3-foliolate, the 

 lower surface (with the petioles and branchlets) pubescent with very 

 short spreading hairs, glabrate above; leaflets oblong-oblanceolate, 

 acutish or obtuse, cuncate at base, entire, puncticulate, 1 to 2\ inches 

 long : sterile flowers small, in a very short terminal few-flowered pani- 

 cle, with very short triangular sepals and 4 (or 5) narrow oblanceo- 

 late valvate petals, concave and spreading : disk inconspicuous or 

 none, the stout filaments (usually 4) inserted at the base of the small 

 abortive ovary ; anther-cells distinct to above the middle, acute at 

 base, rounded above : fruit on short stout pedicels solitary at the ends 

 of short branchlets, depressed-globose (6 to 9 lines broad), mostly 2-3- 

 celled and 2-3-seeded, the oblong-obovate seeds G lines long. — The 

 fruit is essentially that of S. Grc(jfjii, though less lobed, but the flowers 

 differ so widely in being usually tetramerous, with valvate petals, no 

 disk, and dissimilar anthers, that the correctness of the reference to 

 Sargentia is very doubtful. The fertile flowers are as yet, however, 

 unknown. In S. Greggii the anthers are cordate with an acute apex. 

 Found in the mountains of San Luis Potosi at San Jose Pass, in June, 

 1890, in fruit, and in July in flower (n. 3220), It appears to have 

 been also collected by Berlandier in 1828 at INIonterey, without flowers 

 or fruit, the specimen in the Gray Herbarium without num])cr, under 

 the name of Choisya iernata. 



Xanthoxylum Pringlei. A tree, becoming 40 feet liigh, gla- 

 brous : leaflets 3 to 5 pairs, lanceolate, acuminate, rounded at base, 

 entire, coriaceous, epunctate or with a {ew large glandular dots near the 

 apex, 1^ to 2.} inches long on petiolules 1 to 2 lines long : flowers di- 

 oecious, very numerous in large terminal corymbs ; pistillate flowers 

 with a very short 3-lobed calyx and three elliptical petals: carpels 

 solitary ; fruit globose, tubcrculate, 1^ lines in diameter. — In Tama- 

 sopo Caiion, San Luis Potosi, in June, in flower ; October, in fruit 

 (n. 3102). 



NEOPRINGLEA. As the genus JJm'ea of Liebmann is long ante- 

 dated by the Llavea of Lagasca, a genus of ferns that is generally 

 considered as well founded, it is necessary to substitute another name 

 for that of Liebmann. I take pleasure in dedicating the genus to one
