or somewhat spatulate (or upper filiform) divisions of somewhat equal length: 
peduneles surpassing the leaf, 1 to 3-flowered: sepals acute, glabrous, somewhat 
keeled, outer ones salient and often undulate-cristate or tuberculate: corolla pink - 
purple or paler, 8 to 10 mm, long, with 5 short mucronate-pointed lobes: pod as long 
as calyx: seeds minutely puberulent.—Southern and western Texas, 
++ a+ 4+ r+ Stems slender, freely twining: leaves pedately parted into filiform divisions. 
19. I. tenuiloba Torr. Glabrous: leaf-divisions 5 or 7, much longer but hardly 
broader than petiole: peduncle stouter and longer than petiole, 1-flowered: calyx- 
lobes oblong, mucronate-acuminate: corolla pink-purple, 5 to 7.5 cm. long.—“ Hills 
near Puerto de Pay sano, western Texas (Bigelow).” 
Two new species of Ipomea, described from Nealley’s collections in Contrib, Nat. 
Herb. 1. 45, are disposed of as follows: 
I. NEALLEYI was described from specimens of the Ipomea-like Antirrhinum 
maurandioides Gray. 
I. TEXANA, taken to be an indigenous Ipomema, proves to be an escape from culti- 
vation, and is the Brazilian J. fistulosa Mart. 
3. JACQUEMONTIA Choisy. 
Mostly with aspect of Convolvulus, with undivided style, and 2 ovate 
or oblong thick but somewhat flattened stigmas: otherwise as [pomea 
and Convolvulus, and intermediate between the two. 
1. J. tamnifolia Griseb. Erect or at length twining, fulvous-hirsute: leaves cor- 
date and ovate, long-petioled, pinnately veiny: peduncles elongated, capitately 
many-flowered: glomerate cluster involucrate with foliaceous bracts: sepals subu- 
late-linear, ferrngineous-hirsute, 10 mm. long, nearly equaling the violet corolla.— 
Extending from the Gulf States through Texas to tropical America. 
4. CONVOLVULUS Tourn. (BINDWEED.) 
Herbs or somewhat shrubby plants (twining, erect, or prostrate), with 
funnelform to campanulate corolla, included stamens, style undivided 
or 2-cleft only at apex, 2 linear-filiform to subulate or ovate stigmas, 
and globose 2-celled pod (or imperfectly 4-celled by spurious partitions, 
or by abortion 1-celled). 
* Stigmas oval to oblong: calyx inclosed in 2 broad leafy bracts. 
1. C. sepium L., var. repens Gray. More or less pubescent: freely twining, but 
sterile and sometimes flowering stems extensively prostrate: leaves more rarrowly 
sagittate or cordate than in type, the basal lobes commonly obtuse or rounded and 
entire: bracts commonly acute: corolla white or tinged with rose-color, 3.5 to 5 cin. 
long. (Calystegia sepium, var, pubescens Gray.)—On banks and shores, from Atlantic 
States through Texas to New Mexico. 
** Stiqmas filiform or narrowly linear: no bracts at or near the base of the calyx.

2. C, hermannioides Gray. Sericeous-tomentulose: stems 9 to 15 dm. long, 
mainly procumbent: leaves oblong or oblong-lanceolate, obtuse, with sagittate or 
narrowly cordate base, 3.5 to 7.5 cm. long, repand or sinuate-dentate (sometimes 
obsoletely so), rather short-petioled: peduncles 1 or 2-flowered, rather longer than 
leaves: sepals about 12 mm, long: corolla white, 2.5 mm, long, the border merely 
angulate.—Dry prairies of central and southern Texas. 
3. C. incanus Vahl. Cinereous or canescent with a short close silky pubescence: 
stems filiform, 3 to 9 dm. long, mainly procumbent: leaves polymorphous; some 
simply lanceolate or linear-sagittate or hastate (2.5 to 5cm. long and 4 to 6 mm.
