 = Almost sessile and the divisions all simple : root perennial, an oblong tuber. 



I. muricata, Cav. A span or two high, erect, loosely branched, glabrous, slender : leaves 

 of 5 (or sometimes pedately 7) narrowly linear or filiform mueronate-acute divisions or 

 leaflets (6 to 10 lines long) : peduncles shorter than the leaves, 1-flowcred : sepals lanceo- 

 late-ovate, tuberculate-muricate on the back or midrib: corolla narrowly funnelform,

= = Leaves distinctly petiolate: root annual: stems diffuse, filiform. 



I. leptotoma, Torr. Diffuse or procumbent and feebly twining, a foot or two long, 

 glabrous up to the pedicels : leaves pedately 5-7-parted into narrowly linear attenuate- 

 acuminate or acute divisions; the middle and longer one an inch or two long: peduncles 

 slender, equalling or exceeding the leaf, 1-2-flowered : pedicels and lanceolate attenuate- 

 acuminate 3-nervcd sepals hirsute : corolla funnelform, purple, over an inch long : capsule 

 globose-ovoid, shorter than the calyx : seeds glabrous. Bot. Mex. Bound. 150. Arizona,

I. COStellata, Torr. 1. c. Erect and diffuse, at length procumbent or slightly twining, 

 glabrous or minutely hirsute: leaves pedately 7-9-parted into linear or somewhat spatulate 

 (or the upper into filiform) divisions of somewhat equal length (half to an inch long) : 

 peduncles filiform, surpassing the leaf, 1-3-flowered : sepals ovate-lanceolate or oblong, 

 acute, glabrous (as is the pedicel), carinately 1-nerved or obscurely 3-nervcd; the keel of 

 the outer ones salient and often undulate-cristate or tuberculate : corolla narrowly funnel- 

 form, approaching salverform, a third or hardly half inch long, twice or thrice the length 

 of the calyx, pink-purple or paler, with 5 short mucronate-pointed lobes : capside globular, 

 as long as the calyx : seeds minutely puberulent. S. Texas to Arizona. (Mex.) 



3. JACQUEM6NTIA, Choisy. ( Victor Jacquemon*, a French naturalist 

 and traveller, died in India.) A rather small genus, tropical or subtropical, 

 mostly with the aspect of Convolvulus. Fl. summer. Seeds in ours roughish. 



J. ABUTILOIDES, Bcnth., to which belongs Dr. Kellogg's Aniseia cizurca, is of Lower Cali- 

 fornia. It is doubtful if either of the following are indigenous. 



J. Violacea, Choisy. Twining, pubescent or almost glabrous : leaves cordate or ovate- 

 lanceolate,- cuspidate-acuminate : peduncles slender, umbellately or cymosely several- 

 flowered : sepals ovate, acuminate ; the outer larger and subcordate ; corolla short-funnel- 

 form, half inch long, violet. Chapm. Fl. 344. Convolvulus ri<>l<tr< us, Vahl. C. pcntanthos, 

 Jacq. Ic. Rar. ii. t. 31G ; Bot. Mag. t. 2151. Key West, Florida, Blodyrtt. (Trop. Amer.) 

 J. tamnifolia, Griseb. Erect or at length twining, fulvous-hirsute : root annual : leaves 

 cordate and ovate, long-petioled, pinnately veiny : peduncles elongated, capitatcly many- 

 flowered : glomerate cluster involucrate with foliaceous bracts : sepals subulate-linear, fer- 

 rngineons-hirsute, 5 lines long, nearly equalling the violet corolla. Fl. W. Ind. 474 ; 

 Meissn. in Fl. Bras. vii. 302. Jpomaca tamnifolia, L. (Dill. Elth. t. 318, fig. 414.) Convolvulus

4. CONVOLVULUS, L. BINDWEED. (From convoho, I entwine.) - 

 Herbs or somewhat shrubby plants (of many species, most of them in the Old 

 World), either twining, erect, or prostrate ; with small or rather large flowers (in 

 summer), some opening at dawn, some in bright sunshine. Convolvulus & Caly- 

 stegia, R. Br. ; Benth. & Hook. Gen. ii. 874. 



1. CALYSTEGIA. Stigmas from ovate or oval to oblong, thickish : solitary 

 flower involucellate by a pair of persistent membranaceo-foliaceous broad bracts, 

 which are close to the calyx and enclose or exceed it : corolla open in sunshine : 

 ovary and capsule commonly somewhat one-celled by the imperfection of the par-
