244 SOLANACE^E. Bouclietia. 



Waste grounds and coasts, S. Florida and Texas to California ; also adventive at some 

 seaports of the Atlantic States: an insignificant little weed. (S. Amor., &c.) 



16. BOUCHETIA, DC. (In memory of D. Bouchet, an obscure botanist 

 of the south of France.) Prodr. xiii. 589, in part; Benth. & Hook. Gen. ii. 

 908. Single species. 



B. erecta, DC. 1. c. Much branched from a perennial root, ascending, a span high, mi- 

 nutely appressed-pubescent : leaves oblong-spatulate, or the lower oval and petioled, and the 

 upper lanceolate and sessile, rather small: peduncles terminal or lateral and scattered: 

 corolla white, 6 to 9 lines long, about twice the length of the calyx ; the broadly funnel- 

 form limb deeply 5-lobed ; lobes roundish. Nierembergia anomala, Miers in Lond. Jour. Bot.

17. LEPTOG-L.6SSIS, Benth. (^arrotf, thin or small, and j-JLaxraiV, in 

 place of J-P.WTT/V, the mouth of the windpipe, the throat of corolla being narrow.) 

 Extra-tropical S. American herbs, resembling Nierembergia (which has 5 fer- 

 tile stamens borne at and exserted from the orifice of the open saucer-shaped 

 limb), but with tubular-funnelform throat, in the lower part or base of which the 

 didynamous stamens are inserted. Besides the genuine species, a Texan and a 

 Mexican species constitute a subgenus, 



1. BRACHYGLOSSIS, with strictly salverform corolla of Nierembergia ; the 

 long and filiform tube abruptly saccate-dilated just under the ample rotate limb : 

 stigma rather narrowly 2-lobed, and the lobes alate-decurrent on the apex of the 

 style : habit and foliage of Bouclietia. Gray, Proc. Am. Acad. xii. 1G4. 



L. Texana, Gray, 1- c- Low perennial, diffusely much branched from a suffrutescent 

 base, a span high, viscid-pubescent: leaves spatulate-obovate or oblong, acute (half inch 

 long), narrowed at base, the lower into a short margined petiole : peduncles mostly shorter 

 than the eampanulate-funnelform 5-toothed calyx (the teeth deltoid) : corolla apparently 

 white ; the filiform tube 8 or 9 lines long; the almost regular broadly 5-lobed plane limb 

 of about the same diameter ; the very short campanulate throat hardly over a line in 

 height ami width: winged appendages under the stigma narrower than long: capsule only 

 half the length of the 10-nerved calyx: seeds somewhat reniform, coarsely transverse- 

 rugose, otherwise smooth. Nierembergia (Leptoglossis) viscosa, Browallia (Lpptoylossis) 

 Te.ra/in, Torr. Bot. Mex. Bound. 155, 156. Rocky hills, W. Texas, Writ/lit, Bitjelow. (Ad- 

 jacent Mexico, at San Carlos, Berlundicr, no. ."194.) L. Coulter!., Gray, I.e., a nearly related 

 Mexican species of this section, is minutely pubescent, and has ovate leaves on slender 

 petioles, longer peduncle, calyx cleft to the middle, and very broad wings to the apex of 

 the style. 



ORDER XCVI. SCROPHULARIACE.E. 



Herbs, shrubs, or rarely small trees, with leaves either alternate or opposite 

 and destitute of stipules, primary inflorescence centripetal and the secondary when 

 developed centrifugal, perfect flowers with the bilabiately irregular corolla (5) 

 imbricated and not plicate in the bud, didynamous or diandrous stamens, 2-celled 

 ovary with axile several-many-ovuled placentae, usually capsular fruit, and ana- 

 tropous or amphitropous seeds (generally numerous), with a small and straight or 

 only slightly curved embryo in fleshy albumen, the cotyledons little if at all 

 broader than the radicle. The calyx and corolla are mostly 5-merous, and the 

 former persistent ; but sometimes they are 4-merous, at least apparently, and
