 late, lanceolate or ob-lanceolate, petiolate, stipulate, acute or sub-obtuse, tapering

 long, 4 to 1 G lines wide ; petiole 1 to .3 lines long ; stipules subulate, 2 lines long. 

 Flowers solitary, axillary on the short leafy branches, Calyx tubular, cylindric, 

 5-toothed, the teeth deltoid, acute, minutely ciliate, 1 line long ; tube 4 lines long, 

 2 lines wide, a little constricted above the ovary, green, glabrous. Corolla salver- 

 shaped, in bud the limb pink, the tube green, at maturity the whole flower white 

 with faint pink tinge beneath, tube cylindrical, widening in upper portion, 1^ inch

Of this genus three species have already been figured in this work, viz., G. 

 citriodora and G. Thunbergia in vol. 1, pi. 25 & 40, and G. globosa in vol. 4, p. 876, 

 but the species here described differs in several important respects from any of 

 them. It is a shrub with very long straggling branches, and is armed with sharp 

 thorns or spines ; the flowers are, however, conspicuous and handsome, and the 

 plant is well worth cultivation. I have no information of its being collected in any 

 other locality than those given above, nor have I any record of its being introduced 

 into cultivation.
