434 SUPPLEMENT. 



I. carnosa, U- Br- Prodr. 485. This proves to be tlie oldest name in the genus for /. aceto- 

 scefulia, Ua-ni. & Schult., and p. 211, and has been taken up as such. 



I. capillacea, l)ox, Syst. iv. 267. Taives the place of the preoccupied name /. muricata, 

 Cav., p. 214. /. annatci, Rcem. & Sclmlt., is still earlier, but is obviously false. The genuine 

 species has an oblong tuber, erect stems and branches a foot or more in height, leaves of 

 such slender divisions as to justify the present specific name, and peduncles hardly longer 

 than the calyx. The commonest form in Mexico, extending to Venezuela : in Arizona 

 forms occur between tliis and 



Var. patens. Stem and branches short and diffusely spreading : divisions of the 

 leaves from filiform to narrowly linear and obtuse. — Not rare in Arizona and New Mexico. 

 In Northern Mexico, Parry & Palmer's 626 and Palmer's 910 are characteristic, and of the 

 broader-leaved kind. 



I. Plummerse. Tuber globose (not half-inch in diameter) : stem declined-trailing or even 

 disposed to twine, a foot or so long : divisions of the mostly pedate leaves from narrowly 

 spatulate-linear to nearly filiform : peduncle hardly shorter than the (inch long) corolla : 

 otherwise like the preceding, with which it has been confounded in the collections. — S. 

 Arizona, Wri(jht, Loew, and Air. & Mrs. Lemmon (no. 2839), who pointed out the characters. 

 Wherefore Mrs. Lemnion's maiden name is given to it. 



I. CUneifolia, Gray. Tuber, peduncles, flowers, and habit of the preceding : leaves simple, 

 cuneate, laciniate-dentate at the broad apex, tapering into a short petiole, coriaceous in 

 texture, nervoso. — Proc. Am. Acad. xix. 90. — S. Arizona, in the Iluacliuca Mountains, 

 Lem7iw)i. 



I. Leminoni, CtRay, 1. c. Very like /. leptotoma, p. 214, but perennial from a thick oblong 

 tuber, smooth and glabrous tliroughout, eveu to the calyx : stem feebly turning : divisions 

 of the pedate leaves narrowly linear, elongated (often 2 inches long) : peduncle filiform, as 

 long as the slender petiole, one-flowered ; tlie pedicel above the linear-sulmlate bracts very 

 short : sepals oblong, acute, thin, with midrib slightly muriculate : corolla lung aud narrow 

 (2 inches long), ro.se-color. — S. Arizona, in the Huachuca Mountains, Lemmon. 



I. tenuiloba, Torr. Needs a separate subdivision at end of the genus : slender stems 

 freely twining : root unknown : plant glaljrous and smooth : leaves pedately jiaried ; the 

 divisions 5 or 7, filiform, entire (inch and a half long), much longer but liardly broader 

 than the petiole : peduncle stouter and longer tlian the petiole, one-flowered : calyx-lobes 

 oblong, tliinnish, mucronate-acuminate : corolla, &c., apparently nearly as in /. safjittata. — 

 Bot. Mex. Bound. 148 (excl. the remark on no. 1617, wliicli Avas accidentally transposed 

 from the account of /. longifolia) : by oversight omitted from the Flora. — Hills near Puerto 

 de Paysano, W. Texas, Bujelow. 



3. JACQUEMONTIA, Choisy. (Genus too near Convolvulus.) 



J. tamnifolia, Griseb., p. 214. Add syn. : Convolvulus condensatus, Bertol. Misc. Bot. 

 xiv. 18. t. 2. 



J. Pringlei, Gray'. Of the .7. violacea type, near J. ahutiloides, Benth., of Lower California, 

 equally of Abutilon aspect, erect and diffuse from a woody base, not at all twining : leaves 

 cordate, mostly acute or short-acuminate, entire, an inch or half-inch long, canescent- 

 tomentose, also a glabrescent form : peduncles longer than the leaves, loosely 2-4-flowered : 

 pedicels short : sepals ovate, the two inner thin and much smaller : corolla white, with 

 limb nearly an inch broad. — Proc. Am. Acad. xvii. 228. — Santa Catalina Mountains, 

 S. Arizona, Princ/le. 



4. CONVOLVULUS, L. 



Caltstegia PARAr)6xA, Piir.sh, referred to on p. 215, is to be absolutely excluded from 

 our flora. The original, identified in Sherard's herbarium, is Convolvulus sagiUatus of Sib- 

 thorp, C. hirsulns, Bieb., of Greece. See Proc. Am. Acad. xvii. 228. 



C CatesbeiAna, Pursh, is one of the ambiguous forma between C. sepmm, var. repens, and 

 C. spithamcEus, as seen in the Sherardian herbarium.
