316 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [VOL. 35
Cassia flaccida Clos in Gay, Fl. Chile 2: 238. 1854.—". . . en las provincias centrales, en
tero, Valparaiso, etc."—Lectoholotypus, Gay 139 from La Serena in 1836, P! paratypus,
Gay 115, s. loc, P!—Equated by Bentham, 1871, p. 541, with C. coquimbensis.
Cassia coquimbensis sensu Bentham, 1871, p. 540, exclus. syn. C. cumingii ^; Hooker fil,
Curtis's Bot. Mag. Ill, 44: t. 7002. 1888.—raised at Kew from seed collected by British
Consul J. Grierson at Coquimbo, and represented at K by vouchers of wild and cultivated
material!
Differing from other forms of 5. cumingU in ample fohage, larger dohchostylous
fls and more numerous ovules, the pubescence on average longer and more often
yeUow; hts 4-6(-7) pairs, varying in outUne from broadly obovate to elliptic-
obovate or oblance-eUipric, commonly obtuse or obtuse-mucronulate, rarely
emarginate or depressed-acuminulate, the larger ones (10-) 13-31 x (4.5-)7-16
mm, 1.4-2.6(-3) rimes as long as wide, the secondary venulation usuaUy prominulous
on both faces, more sharply so beneath: seeds 5.5-7.2 x (4-)5-6.3 mm,
the areole 4-5.5 x 4.3-5 mm; otherwise as given in key.—Collections: 20.
Coastal hiUs and gulches leading to the ocean, not recorded from above 300 m
but probably ascending somewhat higher in interior valleys, Coastal Cordillera
of centr. ChUe between 29°30' and 32°S in deptos. La Serena, Coquimbo and
OvaUe of province Coquimbo.—Fl. primarUy IX-II, sporadicaUy later, sometimes
while bearing mature pods.
A handsome floriferous senna, worthy of trial in gardens that can provide
Mediterranean conditions. In the field it is hkely to be confused only with S.
candolliana, which has very similar individual flowers but more elaborately ven­
ulose leaflets, a subterete pod and unmarked seeds.

Cassia andina Philippi, Linnaea 28: 685. 1858.—"In Andibus depart. Linares invenit ornat.
Germain."—No typus seen; the sheet at tB = F Neg. 1650 from Cord, de Linares, marked
as a typus, is attributed on the label to Philippi, not to Germain; specimens of Germain at
BM, BR, FI, K, P, W! from Cord, de Maule have, like that at B, only 4-5 (not 8) pairs of
lfts.—C. arnottiana var. andina (Philippi) Reiche, Fl. Chile 2: 40. 1897.—Reduced to C.
arnottiana by Bentham, 1871, p. 539.

but the protologue together with F Neg. 1704\ of isotypus at fB, decisive.—Equated with
C. arnottiana by Burkart, 1952, p. 166.

Low several-stemmed shrubs of bushy outhne 1.5-8 dm, with leafless trunks
at first brown smooth corpulent, then gray or grayish-brown and toughly woody,
up to ±1 cm diam, permanently angulate by prominent, dorsaUy blunt-keeled If-
spurs distaUy wider than the associated If-stalk, the densely leafy young stems,
lf-stalks and axes of inflorescence minutely pUosulous or remotely puberulent
with fine spreading, incumbent or curly white hairs up to 0.15-0.3 mm, the firmly
chartaceous or subsucculent fohage ohvaceous or glaucescent, often yeUowing
in age, the subconcolorous lfts glabrous or remotely ciholate only along midrib
