half-whorls, or scattered : flowers perfect ; petals pink, orbicular, 

 deciduous : stumeus 4, with small elliptical anlht-rs : fruit a liue long, 

 smooth, the narrow carpels rounded or acutish on the back. — In 

 ponds in canons of the Sierra Madre, Chihuahua ; October, 1889

CuPiiEA (Diploptychia) Piunglei. Tall (2 or 3 feet), very 

 scabrous, slender: leaves opposite, narrowly lanceolate, acuminate, 

 cuueate at base, 2 or 3 inches long, those on the branchlets much 

 smaller and the upper cauline narrowly linear : flowers in a terminal 

 glandular-hispid panicle, on slender alternate or opposite pedicels ; 

 calyx scarlet, narrow, 9 or 10 lines long, strongly gibbous at base, 

 the teeth nearly equal ; dorsal petals bright scarlet, oblong-obovate 

 with a short claw, 5 lines long, the ventral minute: stamens 11, 4 

 shortly exserted : disk thick and pyramidal, suspended from the base 

 of the ovary: seeds about 30. — In mountain caiions near Lake 

 Chapala ; December, 1889 (n. 2424). A very showy species, near

Begonia uniflora. Stem thick and fleshy from a small tuber- 

 ous root, procumbent, a foot long or less, smooth and glabrous or 

 somewhat verrucose : leaves thin and nearly glabrous, round-cordate,

 nearly equally 3-winged. — In the Sierra Madre near Monterey ;
