hairs ; bushy branching, from a suffrutescent base ; branches erect, 
9’-18’, not climbing ; leaves opposite, on rather long petioles, pinnate ; 
leaflets 5 pairs, ovate or lanceolate, acute or acuminate, petiolate, 
strongly veined beneath, the lower ones often 2-3 cleft ; flowers axillary 
and terminal, nodding ; peduncles 3’-6’; sepals 4, ovate, with reflexed 
summits, nearly one inch long, dark or brownish purple, thickish but 
not leathery, as in C. Viorna, more or less tomentose on the outside ; 
carpels silky pubescent, with densely plumose tails, 1’-14’ in length.”* ©

6. C. ocHRoLEUcA, Aiton (C. ovata,+ Pursh).—Stem simple, silky 
pubescent, leaves reticulately veined, ovate, sometimes 3-lobed, sub- 
sessile, upper surface glabrous when old, silky beneath ; upper leaves 
rather acute ; flower solitary, terminal, pedunculate, inclined, yellow- 
ish or greenish, erect in fruit ; sepals 4, silky externally ; tails of the 
carpels very plumose. t 
Var. Fremontu, James (C. Fremontii,§ Wats.).— Stem stout and 
usually branched; leaves sessile; sepals purple; tails of carpels short, 
naked above, silky or hairy at base. 
Between the C. ovata, Pursh, and -C. ochroleuca, Aiton, I can not 
find sufficient difference to justify a separation. ‘The characters dis- 
tinguishing the two species are only the silky stem and leaves, and 
yellow flowers of ochroleuca, against the smooth stem and leaves, 
und purple flowers of ovata. But the older leaves of ochroleuca 
become glabrous, and so resemble the ovata: and as Pursh de- 
scribed his species from a dried specimen, he may well have taken 
the flower to be purple, because a difference in color would not be 
noticeable in dried specimens. I have seen but a single specimen 
labelled ovata in any of the large herbaria of the East, and that at

+ C. ovata, Pursh.—Whole plant glabrous ; stem simple, or sometimes climbing ; leaves 
broadly ovate, on very short petioles, glabrous, glaucous and reticulately veined beneath, 
the lower subcordate ; peduncle terminal, solitary, one flowered; flower inclined, nearly 
as large as C. ochroleuca; sepals ovate, acuminate, pubescent on margin, purple; tails of car- 
pels plumose. (Torr. & Gr. Fl. vol, i., pp. 8 and 657.)

2 C. Fremontit, Watson.—‘** Stem stout, erect, clustered, 6’-12’ high, leafy and usually 
branched, more or less villous tomentose, especially at the nodes; leaves simple, 3-4 pairs, 
coriaceous and with the veinlets conspicuously reticulated, sparingly villous, sessile, broadly 
ovate, entire or few toothed, 2’-4’ long; flowers terminal, nodding, the thick purple sepals 
an inch long, narrowly lanceolate; tomentose at the margin, recurved at the tip, the pe- 
duncles becoming erect in fruit, akenes silky 3-4 long, the tails less than an inch long, 
naked above, silky at base.’? (Proc. Am. Acad. vol. x., p. 339. Quoted in Bot. Gaz., vol.
