500 CIX. ACANTHACEE, (C. B. Clarke.) [Eranthemum. 
10. E. leptanthus, C/arke; leaves elliptic acuminate ab both ends 
glabrous, racemes elongate many-fld. subglabrous, corolla small tube i4 in. 
linear curved. 
MisHMEER HILLS; Griffith (Kew Distrib. n. 6181). . 
Apparently a large herb; branches subterete, glabrous. Leaves 7j by 2i n. not 
or very obscurely lineolate; nerves 11-16 pair; petiole 1-1} in. Racemes 5-9 in, 
1-5 subterminal, nearly simple; pedicels fascicled, unusually long, upper often j in. ; 
bracts at the base of the pedicels, minute, linear. Sepals $ in., linear-lanceolate, 
glabrous, margins puberulous. Corolla glabrous; tube linear, slightly inflated, base 
gibbous; limb subequally 5-lobed. Stamens 2, with 2 minute linear rudiments ; 
filaments somewhat ligulate, glabrous; anthers oblong ; cells straight, parallel, muti- 
cous, on the same level exactly. Pistil glabrous; disc annular; ovary 4-ovulate ; 
stigma minute, obscurely bifid. Capsule not seen.—A species differing widely from 
all others, but referred by Mr. Bentham to this genus, of which it appears to possess 
all the essential characters. 
SPECIES IMPERFECTLY KNOWN. 
11. E. GRACILIFLORUM, Nees in Wall. Pl. As. Rar. iii. 107, and in DC. Prodr. 
xi. 454; leaves 8 by 34 in, elliptic acute at both ends subglabrous, nerves 7-9 pair 
puberulous beneath, petiole 2-34 in. puberulous, thyrse 4 in. dense-fld. and densely 
pubescent, pedicels 0—4 in., bracts } in. linear, sepals $ in. pubescent, corolla-tube 
lj in. linear for } its length. Justicia graciliflora, Wall. Cat. 2427.—Penang Mts. ; 
Wallich (specimens without fruit, and with only a very imperfect flower). 
12. E. BIFARIUM, Nees in DC. Prodr. xi. 458; leaves ovate attenuate at both 
ends glabrate, spike small puberulous, flowers solitary opposite, bracts and bracteoles 
linear-subulate shorter than the calyx. Gendarussa bifaria, Wall. Cat. 7173; Nees 
i» Wall. Pl. As. Rar. ii. 104.—Pegu; Pingee, Wallich—Leaves 7 by 34 im. 
entire, minutely lineolate on both surfaces; petiole 1j in., puberulous. Spike (one 
only seen) 24 in., puberulous; flowers j in. apart. Calyx-segments i in., linear, 
pubernlous. Corolla not seen. Capsule 3—1 in., altogether of .Eranthemum. —Nees 
founded this on the 2 opposite lines of minute crisped hairs near the tips of the 
branches; which may be seen in E. album, malaccense and others. The solitary 
example of E. bifarium in Herb. Wallich differs from the neighbouring species 1n its 
depauperated spike and long-petioled leaves, but it is impossible to say that it may 
not be one of them. 
13. E. PUBESCENS, Roth Nov. Sp.1; leaves ovate obtuse, spikes terminal sub- 
distichous, bracts imbricated obovate-oblong mucronate keeled densely pubescent, 
calyx unequal scarious. Nees in DC. Prodr. xi. 458.—India; Heyne.—A shrub ; 
branches subtetragonous, ashy farinose. Leaves from oblong to ovate, nearly entire, 
nervose, paler beneath, farinose ; petiole 1 in. Spike terminal, 3 in., enveloped at base 
by 4 or 5 ovate acute bracts ; proper bracts } in., dense clothed with capitate hairs; 
bracteoles 2, linear-subulate. Calyx 5-leaved, 2 lanceolate subulate, 1 broader 2-nerver 
sub-bifid, 2 smaller. Corolla showy, pubescent without ; tube 1 in. filiform, limb 0 
5 subequal round Jobes. Stamens 2 with oblong villous anthers, 2 sterile very short 
Style long, tip semi-bifid. Capsule oblong-ovoid, 4-seeded. Seeds brown, compressec 
ovate subrotund, under a lens elegantly clothed with imbricated adpressed ferruginous 
scales. 
XXVII. CODONACANTHUS, Vees. 
Corolla small ventricose nearly from the base.—Otherwise as Eran- 
themum. 
The solitary species differs from Eranthemum indicum in its very small flowers ; 
from E. leptanthus in its ventricose corolla. l 
C. pauciflorus, Nees in DC. Prodr. xi. 103; leaves elliptic 
acuminate at both ends pubescent on the nerves beneath or glabrate,
