The determinations of the Gamopetalce, with the descriptions and 

 notes upon them, are as given by Dr. Gray. The Juncacece and 

 Cyperace(B have been named by Dr. N. L. Britton, and the Graminece 

 by Dr. George Vasey. Professor D. C. Eaton has elaborated the 

 Filices. 



Clematis gross a, Benth. Guadalajara ; October. (690.) 



Eanunculus Hookeri, Schlecht., var. (?) with more abundant 

 hairs throughout, spreading upon the pedicels instead of appressed, 

 and with more numerous carpels in oblong-ovate heads. Rio Blanco ; 

 June. (24.) — From the failure to identify Schlechtendal's species 

 with any earlier named one of the Mexican flora his name is still 

 retained. 



Delphinium ? A low species, the specimen insufficient for 



identification. Rio Blanco ; October. (672.) 



Anona (Cherimoli^) longiflora. a low shrub (3 feet high), 

 the young branches, pedicels, and petioles densely soft-pubescent: 

 leaves ovate-elliptical, rounded at base, acutish or' obtuse, 2 to 4 

 inches long, softly pubescent (densely so when young), becoming 

 nearly glabrous above : flowers pubescent, densely so at base ; sepals 

 deltoid-ovate, 2|- lines long ; outer petals linear-oblong, nearly 2 

 inches long, convex at base, glabrous within, " whitish cream-color 

 with a black base," the inner wanting or minute : fruit globose-ovate, 

 1|- inches long, covered with flat reticulations : seeds smooth and 

 shining. Rio Blanco, in ravines ; June. (55.) — Bourgeau's 2482, 

 from Orizaba, in herb. Gray, appears to be the same as to the sterile 

 leafy branch, but the flowering stem is A. Cherimolia, and probably 

 belongs with his n. 2481, from the same locality. 



Nymph^a gracilis, Zucc. ? Rootstock very short and premorse : 

 flowers white, 3 inches broad, " moderately fragrant " : stamens with 

 a short and rather thick appendage, a line long or less : capsule 8 

 lines in diameter. Guadalajara ; July. (283.) — The appendages of 

 the stamens are shorter and less acuminate than they are described 

 by Zuccarini, and than are those of 5 Bourgeau, so named. 



Casearea corymbosa, HBK. This species is referred to C. m- 

 tida, Jacq., by Grisebach and by Eichler. Palmer's plant is a 

 shrub 3 to 5 feet high, the leaves not shining, narrowly oblong, and 

 obtuse at both ends ; sepals 6 or 7 ; stamens 6 ; fruit oblong-ovate, 

 6 to 8 lines long, dark orange ; seed with adherent crimson aril, and 

 the outer portion of the albumen abundantly resiniferous. Barranca.
