434 SUPPLEMENT. 



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

 safolia, Roem. & Schult., and p. 211, and has been taken up as such. 



I. capillacea, Don, Syst. iv. 267. Takes the place of the preoccupied name I. muricata, 

 Cav., p. 214. I. armata, Eoem. & Schult., 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 this 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. PKimmerse. 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, Wright, Loew, and Mr. & Mrs. Lemmon (no. 2839), who pointed out the characters. 

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



I. CUneif olia, 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, nervose. — Proc. Am. Acad. xix. 90. — S. Arizona, in the Huachuca Mountains, 

 Lemmon. 



I. Lemmoni, Gray, 1. c. Very like I. leptotoma, p. 214, but perennial from a thick oblong 

 tuber, smooth and glabrous throughout, even 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 ; the pedicel above the linear-subulate bracts very 

 short : sepals oblong, acute, thin, with midrib slightly muriculate : corolla long and narrow 

 (2 inches long), rose-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 glabrous and smooth : leaves pedately parted ; the 

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

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

 oblong, thinnish, mncronate-acuminate : corolla, &c, apparently nearly as in 7". sagittata. — 

 Bot. Mex. Bound. 148 (excl. the remark on no. 1617, which was accidentally transposed 

 from the account of I. long] [folia) : by oversight omitted from the Flora. — Hills near Puerto 

 de Paysano, W. Texas, Bigelow.

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



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

 xiv. 18, t. 2. 



J. Pringlei, Gray. Of the J. violacea type, near J. abuttloides, 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, Pringle. 



4. CONVOLVULUS, L. 



Calystegia parad6xa, Pursh, referred to on p. 215, is to be absolutely excluded from 

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

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



C. Catesbeiana, Pursh, is one of the ambiguous forms between C. septum, var. repens, and 

 C. spithamceus, as seen in the Sherardian herbarium.
