FRGLICHIA FLORIDANA, Mog. l. c. Oplotheca floridana, Nutt. Gen. 2, p. 19; Bart. Fl. N. 
Amer, 2, t. 59; Hook. Ic. t. 256. Sand banks of the Canadian; August. F. Drummondii of 
Moquin seems to be scarcely a variety of this species. The fructiferous calyx has a narrowly 
winged and irregularly toothed margin. At the base there is usually a central tooth or pro- 
tuberance on one side, and two protuberances on the other. The same characters occur in F. 
gracilis. 
NYCTAGINEX. 
OXYBAPHUS GLABRIFOLIUS, Vahl, Enum. 2, p. 40; Choisy in DC. Prodr. 13, ( pars 2,) p. 431. 
O. levis, Benth. Bot. Sulph. p. 44. Los Angeles; March 21; and mountains near the Colorado, 
Mexico. 
This species is very variable in its pubescence. If O. laevis of Bentham be correctly referred 
here, it is sometimes wholly glabrous. Our California specimens usually have the branches, 
peduncles, and margin of the leaves slightly pubescent. Those from near the Colorado have 
the branches strongly pubescent, and both surfaces of the leaves more or less so. The perianth 
is rose-colored, and the 5 lobes are emarginate. 
QUAMOCLIDION OXYBAPHOIDES, Gray in Sill. Jour., 2d ser. 15, p. 320. Rocky places, Llano 
Estacado; September. The involucre is unequally 4-5 cleft. Fruit black when dried before 
ripening, but mottled when mature. 
ABRONIA CYCLOPTERA, Gray l. c., p. 319. A. (Tripterocalyx) micrantha, Torr. in Frem. 1st Rep, 
p. 96. Banks of the Rio Grande, near Albuquerque, New Mexico ; October; with flowers and 
fruit, the latter more than an inch in length, with very broad membranaceous wings. 
ABRONIA MELLIFERA, Dougl. in Hook. Bot. Mag. t. 2879; Mog. in DC. Prodr. 13, ( pars 2,) p. 
435. Sandy hills, Indian Territory ; September; with flowers and ripe fruit; and sandy hills 
near the Colorado, California; February. The figure in the Botanical Magazine (copied 
by Lindley, Veg. Kingd.) erroneously shows the embryo with two cotyledons. We have shown; 
elsewhere, that in all the species of Abronia, the inner cotyledon is either wholly suppressed, or 
only rudimentary. Near Galisteo, New Mexico, Dr. Bigelow collected a dwarf variety of A. 
mellifera, with spatulate leaves tapering at base to a long petiole, and large membranaceous in- 
volucres with broadly ovate segments. The fruit resembled that of the ordinary form. 
ABRONIA ARENARIA, Menz. in Hook. Exot. Fl. t. 193; Choisy in DC. Prodr. 13, (pars 2,) p. 
435. Sand-hills near the sea-shore, Punta de los Reyes, California; April 17. 
POLYGONACEH. 
ERI0GONUM POLIFOLIUM, Benth. in DC. Prodr. 14, pars 1, p. 12. Mountain aroyos near 
Williams’ River; February 9. Involucres usually in a capitate cluster, but sometimes on short 
rays. 
fae CORYMBOSUM, Benth. l. c. Var. DIVARICATUM, Torr. € Gray, in Beckwith’s Rep., p. 
123. On sandy hills, near Inscription Rock, Western New Mexico; November 18. 
Errogonum LONGIFOLIUM, Nutt. in Trans. Amer. Phil. Soc. n. ser. 5, p. 164. Dry prairies, 
Upper Cross Timbers of the Canadian River; August. 
ERIOGONUM ORTHOCLADON, Torr. in Sitgreaves’ Hep. p. 167, t. 9; Benth. in DC. Prodr. 14, 
pars. 1, p. 15. Sandy hills, Albuquerque, New Mexico. 
EnrogoNUM ALATUM, Torr. l. c. p. 168, t. 8. Var. GLABRIUSCULUM: caule foliisque vix pube. 
scentibus ; involucris bracteolisque glabris. High prairies, near the Upper Canadian. Plant 
4-5 feet high. Differs from the ordinary form of this species in being taller, nearly glabrous 
in all its parts, (except a slight hairiness on the leaves and lower part of the stem,) and in the 
slender and more numerous branches. It may be E. alatum f. elatum, Benth. in DC. Prodr- 
14, pars. 1, p. 1.
