AcANTHOCHITON W RIGuTII, Torr. Dot. Sitgr. Rep. p. 170, t. 13. Plains among the Burro 
mountains, September ; Bigelow. Los Medanos, Chihuahua, August ; Thurber. These specimens 
are very perfect and enable us to amend the character of Acanthochiton given in the work here 
quoted. There are three somewhat unequal bracts to each male flower. The cells of the 
anthers are separate at the summit, and very acute. The female flowers are mostly ternate and 
are subtended by three bracts, the middle one of which is cordate-falciform and — much 
larger than the lateral ones.

SARRATIA BERLANDIERI, Mog. l. c. p. 268. Mountains of the Cibola, a tributary of the Rio

SARRATIA BERLANDIERI, var. EMARGINATA: foliis oblongo-lanceolatis ; calycis foeminei lacinis 
lato-cuneatis, emarginatis. Camp Green, October; Parry. This variety is about a foot high. 
Except in the lacinie of the perianth, it does not appear to differ from the preceding. 
SARRATIA BERLANDIERI, var. DENTICULATA: foliis lineari-lanceolatis, calycis foeminei laciniis 
lato-cuneatis margine eroso-denticulatis. Santa Cruz, Sonora, September; Thurber. 
БЫА канали, var. FIMBRIATA: foliis linearibus; glomerulis subglobosis densifloris, 
i ibus approximatis subspicatis ; calycis feeminei laciniis zequalibus 
flabellato-cuneiformibus UR dentato-fimbriatis. On the Gila river ; Schott. (No. 582, Wright.) 
Stem 2 feet or more in length, smooth, branching ; the branches E Leaves 14-23 inches 
long, 11-2 lines wide, smooth, tapering at the base. Glomerules of flowers about one-third of 
an inch in diameter, the upper ones aggregated in a long naked spike. Bracts subulate. Peri- 
anth parted nearly to the base; the segments spreading, mostly broader than long, abruptly 
narrowed to a short claw, the summit cut into irregular acute teeth or laciniw. Ovary globose 
ovate; stigmas 3-4. Utricle tubercular-rugous at the summit. Seed lenticular, acute on the 
margin, smooth, and shining. This appears to be quite a distinct species. 
AMBLOGYNA POLYGONOIDES, Raf.; Mog. 1. с. p. 270. Amarantus polygonoides, Linn. Western 
Texas, (No. 1746, Wright.) We have it also from Dr. Gregg, who collected it at Cerro Alto, 
Mexico. The genus Scleropus, of Schrader, is founded on an abnormal state of this plant, in 
which the peduncles and pedicels have become thickened and indurated. We have it in this
