rowed l)ase and loii.o-aeniuinate and acute summit, entire, with 

 rovolute margin, thick, yellow-green, esjoecially beneath, where 

 the midrib is very strong and prominent. Pedicels solitary in 

 their axils, 5 to 10 mm. long, slender, ascending. Calyx-tube 6 

 or 7 mm. long, 4 or 5 mm. wide, cam])anu]ate or cupulate, lightly 

 5-ribbed, with five alternating nerves, the teeth about two thirds 

 the length of the tube, mostly erect, somewhat unequal, subulate, 

 attenuate and very acute. Corolla crimson, reaching 4 cm. or 

 more in length, the tube infundibular, slightly curved and 

 slightly ventricose, reaching 1 em. in breadth, the narrow por- 

 tion about as long as the calyx, the limb about 1.5 cm. broad, the 

 lobes subequal, rounded, or broader than long. Stamens ex- 

 serted, the anthers oblong, 3 or 4 mm. long.

BiGNONIACEAE 



Arrabidaea Cardenasii 



Glabrous, with the exception of the cinereous inflorescence. 

 Branchlets rather stout, finely ribbed or nerved. Leaflets 2, one 

 lateral wanting, the other lateral and terminal very similar. Peti- 

 ole about 2 cm. long, rather stout, the terminal petiolules about 

 equal, the lateral usually a little shorter. Blades to 8 cm. long 

 and 6 cm. broad, the base broad and rounded, usually very 

 slightly produced at the petiolule, the summit produced into a 

 very short and blunt extension ; thick, strongly lucid above, 

 where the slender venation is slightly jirominent, more promi- 

 nent beneath, the secondaries about 6 on a side, widely spread- 

 ing, little curved, the tertiaries almost transverse to the leaf axis. 

 Panicles axillary and terminal, slenderly peduncled, the bracts at 

 the points of branching nearly obsolete, the subulate bractlets at 

 the base of the j^edicels minute. Pedicels about 2 mm. long, slen- 

 der. Calyx 3 nmi. long, 2 mm. wide, camj^anulate-turbinate, mi- 

 nutely subulate-toothed, cinereous, like the branches and corolla. 

 Corolla-tube proper scarcely exceeding the calyx, the expanded 

 portion 7 or 8 mm. long, campanulate, not quite so long as the 

 lobes. Stamens stout, not extending beyond the base of the cor- 

 olla-lobes, and slightly exceeding the style. Appendage to the 

 connective very short and broad, blunt, blackish. Ovary small, 

 about twice the width of the style. Stipe of the pod biglandular 

 at the base. Pod nearly 3 dm. long, 1.5 cm. broad, not, or very 

 faintly ridged, closely tomentellate, the summit not acuminate, 

 acutish or obtuse.
