3. CATAL.PA, Scop. Two North American species are now distinguished, 

 not very definitely, viz. : 



C. bignonioid.es, WALT., p. 319. Low and much-branched tree, with thin bark: leaves 

 (unpleasantly scented) moderately acuminate, and not rarely a pair of lateral salient teeth : 

 corolla hardly inch and a half long, thickly spotted within, the tube campanulate, limb 

 oblique, lower lobe entire : capsule very slender. Exclude from the syn. the figure in 

 Duhamel. S. W. Georgia, Alabama, &c. , and widely cultivated. 



C. speciosa, WARDER. Large and tall tree, with thick bark: leaves (inodorous) caudate- 

 acuminate: corolla larger (2 inches high), nearly white, inconspicuously spotted, and with 

 broader little oblique limb, the tube obconical, lower lobe emarginate : capsule equally long 

 but nearly twice as thick: flowering earlier (May). Engelm. Bot. Gazette, v. 1 ; Sargent, 

 Forest Trees, 10th Census, 115. C. cordi folia, "Jaume" in Duham. ed. nov. ii. t. 5, as to 

 the plate. S. Illinois and adjacent States. A more showy as well as larger and more val- 

 uable tree. First discriminated by the late Dr. J. A. Warder, and scientifically published by 

 Engelmann tinder Dr. Warder's name. 



CRESCENTIA CUCURBITIVA, L. (see p. 320), was collected by the late Dr. Garber in S. Flor- 

 ida : probably not indigenous.

3. CAL.6PHANES, Don. 



C. Oblongif61ia, Dov, p. 324. The sepals much surpass the capsule, and sometimes nearly 

 equal the corolla. The var. anr/itsla should give place to 



C. angusta. A span or two high, erect or ascending from a creeping base, only minutely 

 puberulent, usually very leafy: leaves half to three-fourths inch long, from oblong to 'al- 

 most linear, nl.snn-i'ly veined : flower small: corolla barely half-inch long, rather narrow: 

 sepals distinct to near the base, subulate-setaceous, hardly surpassing the capsule. C. ob- 

 lonyfol'm, var. nnynstn, p. 324. Dipteracnnlhim linearis, Chapm. Fl. 303, not Torr. & Gray.
