with it, reducing to a mere sectional distinction the differences in bracts, 
in the degree of separation of the divisions of the calyx, and in the 
often inappreciable variations of form of the corolla, which make it ne- 
cessary to modify the circumscription and characters of the genera with 
, almost every really new species discovered. 
x$ 5. Dipteracanthus ? calycinus, Champ. sp. n. ; humilis, erectus, glaber, 
foliis oblongis ovatisve dentatis in petiolum angustatis, floribus ad 
apices ramulorum geminis ebracteolatis, calycis lacinia suprema 
latiore.— Herba semipedalis, erecta, subfastigiato-ramosa. Folia 
maxima 3-pollicaria, obtuse acuminata, basi in petiolum longe an- 
gustata, pleraque minora ovata v. summa obovato-spathulata. Flores 
magni, ad apices ramorum sessiles (axillares, oppositi, gemma inter- 
media non vel vix evoluta). Calyz fere ad basin 5-partitus, lacinize 
quatuor lineares, herbaceze, 9-10 lin. longs, acutiuscule ; quinta 
summa paulo longior obtusior et fere 2 lin. lata. Corolla bipollicaris, 
tubi parte tenui calyce breviore, fauce elongata obliqua, intus glabra 
nuda; limbi laciniz late subsequales. Stamina inclusa, didynama, 
filamentis basi connatis, membrana brevi inter stamina superiora 
bidentata. Anthere anguste oblongz, loculis parallelis zequalibus 
muticis. Stylus glaber, filiformis, apice integer setaceus. Capsula 
basi compressa, asperma, a medio 4-sperma, omnino Dipteracanthi. 
Semina orbiculata, leevia. 
Mount Parker. Flowers very large in proportion to the plant and 
pale violet. This again will not fit exactly into any of Nees's genera. 
I have placed it in Dipteracanthus on account of the general habit, the 
form and size of the corolla, and the structure of the capsule; but the 
enlarged upper division of the calyx is not usual in that genus, and the 
apex of the style, though variable, is described as always bilamellate. 
I observe however that in many species the longest division is searcely 
dilated, and the other one occasionally reduced to a small tooth, almost 
as in Ruellia, and this character is perhaps after all of little value 
among the Ruellioid genera. eae

Bind near the Buddhist Temple, East Point. This is a very 
low procumbent and pubescent form, resembling in habit the Z. Java- 
nica, but the flowers, the ciliate anthers, etc., are those of L. hyalina.
