9. Lithospermum. Corolla salverform to funnelform, its rounded lobes spread- 
ing, the throat either naked or with low crests. 
10. Onosmodium. Corolla tubular, unappendaged, its erect lobes acute, 
1. CORDIA Plumier, L. 
Trees or shrubs, with leaves sometimes dentate, tubular or campan- 
ulate calyx merely toothed or lobed, funnelform or salverform corolla 
with lobes and stameus sometimes more than 5, twice bifid style with 
clavate or capitate stigmas, and undivided ovary which becomes a 
4-celled 4-seeded drupe. 
1. C. Boissieri A. DC. Small tree, rarely & m. high: soft-tomentose: leavesoval 
or oblong-ovate: inflorescence open-cymose: corolla large (2.5 to 5 em. long), fun- 
nelform, white with a yellow center, externally downy, the tube longer than the 
somewhat campanulate and striate calyx.—Valley of the Rio Grande and adjacent 
Mexico. Called “anacahuita” by the Mexicans, by whom its various parts are 
much used medicinally, ‘‘The fruit is nearly 2.5 em. leng, with a pointed stone and 
pulpy sweet mesocarp.” 
2. C.podocephala Torr. Woody only at base, 3 to 6 dm, high, minutely strigose- 
hirsute, scabrous: leaves varying trom ovate-lanceolate to linear-lanceolate, coarsely 
serrate: peduncles filiform, 5 to LO cm, long, bearing a small and very dense head of 
white or pale purple flowers: corolla broadly funnelform, its narrow tube (12 min. 
or more long) hardly exceeding the short (not striate) calyx.—From the Lower Rio 
Grande to New Mexico and adjacent Mexico. 
2. EHRETIA L. 
Trees or shrubs, with small white tlowers in open cymes or panicles, 
5-parted or 5-cleft calyx, short-funnelform to rotate corolla, (once) bifid 
or 2-parted style with stigmas more or less capitate, and a drupaceous 
fruit usually containing two 2-celled 2-seeded nutlets. 
1. B. elliptica DC. Tree 5 to 15 m., high: leaves oval or oblong, sometimes ser- 
rate, nearly glabrous or (with the branchlets and open cymes) minutely hirsute- 
pubescent and the upper face very scabrous: calyx-lobes acuminate, as long as the 
campanulate corolla-tube: drupes yellow, globose, of the size of small peas.—In the 
region of the Lower Rio Grande (Corpus Christi to New Braunfels and southward). 
Known as “‘knackaway” and “ anaqua,” 
3. COLDENIA L, 
Low herbaceous or suffrutescent canescent or hispid plants, with 
small and mostly white flowers sessile and usually in clusters, 5-parted 
calyx with narrow divisions, short-funnelform or nearly salverform 
corolla seldom much exceeding the calyx, included stamens, 2-cleft or 
2-parted style, entire or laterally 4-lobed 4-celled ovary, and dry fruit 
separating at maturity into four 1-seeded nutlets (or in one species by 
suppression 1-celled and 1-seeded). 
1. C. canescens DC. Prostrate or procumbent, with somewhat woody base, 
white-sericeous or tomentose: eaves 12 mm. long, ovate or oblong, entire, petioled: 
flowers solitary or in small clusters at the axils or forks: calyx-lobes linear-lanceolate : 
stamens equally inserted: fruit depressed-globose, the 4 thick-walled nutlets with 
plane contiguous sides and smooth and rounded on the back.—Southern and western 
Texas.
