THREE SPECIES OF OLD GENERA. 
Synthlipsis lepidota Rose, sp. nov. Piate LXV. 
Annual, 50 to 60 cm. broad, with many spreading stems from the base, glabrous 
except for the copious minute scales; basal leaves in a rosette, oblanceolate, 7 to 
10 em. long, obtuse, entire or with a somewhat undulating margin with or without 
afew teeth, on both sides clothed with closely set scales, tapering into a slender 
petiole; stem leaves shorter, often with distinct teeth or even lobes; racemes 10 to 
15 em. long; pedicels 8 to 12 mm. long; sepals oblong, covered without with minute 
scales, 4mm. long; corolla pale yellow, in age becoming somewhat purplish, 7 mm. 
long; pods thin-walled, 12 to 14 mm, long, rounded at base and apex, covered with 
small scales, especially when young; style slender, 1.5 to 2 mim. long. 
Coilected by C. G. Pringle near Dublan, State of Hidalgo, July 13, 1898 (no. 6899).

Thelypodium pallidum Rose, sp. nov. 
Biennial, tall (80 to 150 em. high), more or less branched, glabrous and of a pale- 
green color; basal leaves 4 to 6 em. long, lyrate, the terminal lobe rounded and obtuse, 
the other lobes very small, the petiole and under surface somewhat pubescent; stem 
leaves sessile and clasping, glabrous, the margin denticulate; inflorescence elongated, 
sometimes 50 em, long; flowering pedicels spreading, in fruit a little ascending; sepals 
oblong, obtuse, purplish, 2.5 mm. long; petals narrow; anthers sagittate at base; 
receptacle swollen; stigma circular; ovary stipitate; pod ascending, 12 to 20 mm. long; 
seeds rugose. 
Collected by J. N. Rose and Jos. H. Painter near Tres Marias, Morelos, September 
21, 1903 (no. 7209). 
Lepidium granulare Rose, sp. nov. 
Slender, erect, annual or biennial, 40 em. tall, more or less branched throughout, 
not at all pubescent, but somewhat granular; stem leaves pinnatifid, the lobes more 
or less lobed or sharply-toothed; upper leaves often linear and entire; racemes 5 to 8 
cm. long, erect; pedicels ascending, 2.5 mm. long; sepals with scarious margins; 
stamens 2; fruit 2 min. long, distinetly notched at apex, glabrous; style very short; 
seed with cotyledons incumbent. 
Collected by C. G. Pringle in alkaline meadows, City of Mexico, June and July, 
NOL (no 8488). 
Nearest L. sordiduin of north Mexico, but with 2 stamens instead of 4, less granular 
herbage, different fruit, ete. 
CRASSULACEAE. 
TWO NEW SPECIES OF ECHEVERIA. 
Echeveria multicaulis Rose, sp. nov. 
Caulescent, the stem roughened below, naked, crowned near the top by a rosette 
of obovate or spatulate leaves, the whole plant including flowering branches 20 em. 
high in cultivation but said to reach 90 to 120 em. high in the wild state; leaves 
3 to dem. long, 12 to 20 mm, broad at widest point, flattened, mucronately tipped, 
glabrous, the margin and face more or less brightly colored; flowering branches 
bright-colored, bearing scattered oblanceolate leaves; inflorescence a short conmpact 
equilateral raceme; flowers subtended by small bright-colored bracts; pedicels very 
short. but distinet; calyx lobes narrow, acute, ascending, about one-half as bong as 
the corolla; corolla buds acute, angled; corolla reddish without, yellowish within. 
Collected by Ek. W. Nelson and E. A. Goldman near Omilteme, State of Guerrero, 
May, 1905 (Rose’s no. 628) and flowered in Washington, December, 1903.
