'OF THE GENUS OUSCUTA.

Potosi, the same! and Parras, Gregg! — Lindheimer’s nro. 473 is an intermediate form between this and var. pentagona , 
mixed with a few specimens of the following. 
Var. y. pubescens : pedicels and all parts of the flower or only the ovary and the capsule papillose-pubescent. — 
Western Texas, Lindheimer! Wright ! 1635 (574). — Wright’s 519 and 523 (coll. 1849) are a transition form between 
this and the last variety, having the calyx of verrucosa and the ovary and capsule of pubescens. 
Var. 8. calycina : inflorescence often more compact; flowers rather larger; hemispherical calyx not angled, 
lobes rounded or oval, usually longer than the tube ; lobes of corolla broader and shorter than in the other forms, and 
often not longer than the tube. — Texas, Lindheimer! 126 (a form from wet prairies, with smaller flowers) ; the same! 
664; Wright! both on Dianthera, in or along water-courses ; Martinique, Mad. Richard! 114 in Herb. Mus. Flor.; 
Herb. Fauche! (now in Hb. Boissier); Saskatchawan, Drummond! C. Americana? Hook. Fl. N. A.; Oregon, 
Geyer! 674. 
Specimens from Brazil Eschscholtz! in Hb. Ledebour; Gardner! 6068 in part (£ decora has also been distributed 
under this number) differ somewhat from this variety by stouter and, in fruit, subulate styles ; Gardner^ specimens 
have also a smaller calyx. 
* * Flowers arranged in loose compound cymes ; styles usually slender, as long or longer than ovary; withered 
.corolla remaining at base of capsule or enveloping it. 
/ 42. C. trichostyla, n. sp.: caule filiformi; bracteis ovatis obtusis ; floribus breviter pedicellatis in 
cymulas ramosas subglobosas congestis; calycis cupulati fere ad basin divisi lobis ovatis orbiculatisve [496 (46)] 
obtusis basi imbricatis tubuin corollse campanulatum aequantibus seu superantibus ; laciniis ovatis obtusis 
tubo aequilongis demum patulis reflexisve ; antheris ovatis filamenta subulata brevia sequantibus ; squamis late ovatis 
fimbriatis incurvis ; stylis capillaribus ovario depresso multo longioribus e tubo vix exsertis. 
Panama, Tweedie! Santarem, Brazil, on Hyptis , Spruce! 854, both in Hb. Hooker. — None of the specimens 
examined being in fruit, the true position of this species must remain doubtful. The large imbricate calyx, the slender 
styles, and especially the branching inflorescence, distinguish it from C. obtusiflora ; the inflorescence, the shape of the 
ovary and of the styles, from C. Gronovii and C. racemosa. — Flowers 1 j~2 lines long, “ white, with a strong odor of 
hawthorn,” Spruce; exterior lobes of the calyx in the Panama specimen towards the tip verrucose-cristate; in the 
other smooth, thin, and shining ; scales in the former longer than the tube, in the other broader and shorter. 
^ 43. C. gymnocarpa, n. sp. : caule filiformi; floribus breviter pedicellatis umbellato-glomeratis; calycis lobis 
ovatis seu orbiculatis obtusissimis nitidis tubum corollse sequantibus ; laciniis triangulatis acutis erectis seu demum 
patentibus tubo sequilongis ; antheris ovato-orbiculatis filainentum breve subulatum sequantibus ; squamis tenuis- 
simis late ovatis fimbriatis faucem attingentibus; stylis capillaribus ovarium depressum sequantibus supra capsulam 
globoso-depressam e corolla ad basin marcescente longe exsertam divaricatis patentibus recurvisve ; seminibus 
oblique ovatis tumidis tenuissime sub lente reticulatis. — C. Sandmcensis , var. Mimosas , Hook. fil. in Linn. Trans. 
XX. 205. 
James Island, of the Galapagos group, in immense abundance on Mimosa bushes, Chs. Darwin! in Hb. 
Hooker.—Flowers about 1 line long, of a very thin texture; capsule 1J*-1J lines in diameter, with a very small 
intrastylar aperture; seeds, in the only specimen extant, light yellowish brown, 0.6 line long, plump, nearly smooth, 
with a short, oblongrlinear, usually perpendicular, hilum.— Much closer to C. arvensis than to C. Sandwichiana; 
distinguished from both by the short, broad, and very acute lobes of the corolla, and by the very slender, at last nearly 
horizontal, styles; from the latter also by the presence of scales and by the naked capsule. 
V 44. C. Sandwichiana, Choisy! Cusc. 184, t. 5, f. 4; DC. Prod. IX. 458. —Sandwich Islands; apparently the 
only species growing there ; mostly on shrubs ; Menzies l Eschscholtz E Gaudichaud! Matthews! Stewart! Maximo- 
witsch! 57; Remy! 424. — Inflorescence a compound loosely-flowered cyme; flowers pedicelled, 1-1Jlines 
long, u pallide ochracei ” Maxim., of thin, membranaceous texture ; only in Menzies’ specimen in Hb. [497 (47),] 
Banks I find all the parts of the flower dotted with glands; lobes of calyx ovate, acutish; lobes of 
corolla acute and indexed at tip or sometimes obtusish, often reflexed, but at last commonly adpressed to the top of 
the capsule, which for its greater part is enveloped by the tube; anthers oval; no trace of scales; capsule l|-2 lines 
in diameter, with a small, almost circular, intrastylar aperture; styles stouter than in the last species, somewhat 
divaricate on capsule ; seeds unusually large, 0.8-1.0 line long, verrucose-reticulate, triangular-ovate, somewhat 
oblique but not rostrate, with a short linear-oblong perpendicular hilum on the comparatively small regularly circular 
umbilicus. 
Y 45. C. acuta, n. sp.: caulibus subcapillaceis ; cymis compositis laxifioris umbellulas mentifentibus ; pedicellis 
flore brevioribus bracteis ovatis acutis suffultis ; calycis late campanulati membranacei lobis triangulatis aditis, sen 
cuspidatis tubum corollas campanulatum superantibus ; laciniis lanceolatis acutatis tubo longioribus erectis sen sub- 
patentibus; antheris oblongo-linearibus filamento subulato fere brevioribus; squamis ovato-spatulatis longe adnatis
