minute rudiments of the upper stamens, but these exist also, at least 
in my specimens of P. Kunthianum. Specifically P. apricum differs 
from P. Kunthianum by the narrower bracts and calycine lobes, and 
by the greater length of the slender tube of the corolla; the spikes or 
heads of flowers are also much shorter than those of P. Kunthianum, 
but in the latter species they are often very much shorter than in the 
specimen figured by Wight (Ic. t. 448).

Ravines of Victoria Peak. The specimens agree perfectly with those 
from Assam and Sillet. 
ust! 4. Ruellia £efrasperma, Champ. sp. n.; foliis ovatis obtusis crenatis hir- 
tellis, spicis paucifloris plerisque in capitula terminalia subhirsuta 
confertis, bracteis spathulatis, bracteolis linearibus, calycis laciniis 
obtusis basi connatis, ovario 4-ovulato.—Specimina adsunt semipe- 
dalia. Caules basi diffusi, radicantes. Folia breviter petiolata, ru- 
gosa, maxima sesquipollicaria, pleraque vix pollicaria vel etiam multo 
minora. Capitula intra folia suprema sessilia, nunc ad apices ramo- 
rum brevium axillarium quasi axillaria, nunc e spicis pluribus com- 
posita, ad apicem caulis ramorumque densa subglobosa. Bractee et 
bracteole ciliato-hirte, calyee subbreviores, he laciniis calycinis sub- 
conformes, illæ szepius multo latiores. Calyx 2 lin. v. paulo longior, 
fere ad quartam partem longitudinis integer, laciniis 5 herbaceis 
subdilatatis. Corolla violacea, 10 lin. longa, infundibuliformis, tubo 
calycem superante in faucem latiusculam abeunte; laciniæ subæ- 
quales, late, obtusce vel retusee, margine ciliate ; faux intus lineis 2 
longitudinalibus barbata. Stamina didynama, inclusa. Anthere 
ovate, glabre, loculis parallelis muticis. Ovarium sessile, complete 
biloculare, loculis biovulatis. Stylus filiformis hine pilosus, sub apice 
unidentatus, supra dentem subulatus, recurvus, hine stigmatosus. 
Victoria Peak. Technically speaking, this plant might be rather 
better referred to Dyschoriste or Calophanes, for the lobes of the calyx 
are less deeply divided than in the true Ruelliæ, and there are four 
only, not six to sixteen ovules; but the anthers are not calcarate nor 
mucronate as in those two genera, and the inflorescence and general 
aspect is very unlike either of them; whilst the habit, inflorescence, and 
corolla are precisely those most common in Ruellia. It is much to be 
regretted that several of the allied genera, having the style and capsule 
and general form of the corolla of Ruellia, could not have been united
