500 cix. ACANTHACE.E. (C. B. Clarke.) [Eranthemum. 



10. E. leptanthus, Clarice ; leaves elliptic acuminate at both ends 

 glabrous, racemes elongate many-fld. subglabrous, corolla small tube - i n - 

 linear curved. 



MISHMEE HILLS ; Griffith (Kew Distrib. n. 6181). 



Apparently a large herb; branches subterete, glabrous. Leaves 7\ by 2| 'n., uofc 

 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 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. Ear. iii. 107, and in DC. Prodr. 

 xi. 454 ; leaves 8 by 3 in. elliptic acute at both ends subglabrous, nerves 7-9 pair 

 puberulous beneath, petiole 2-3| in. puberulous, thyrse 4 in. dense-fld. and densely 

 pubescent, pedicels 0-^- in., bracts \ in. linear, sepals in. pubescent, corolla-tube 

 1J 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 

 in Wall. PI. As. Rar. iii. 104. Pegu; Pingee, Wallich. Leaves 7 by 3^ in., 

 entire, minutely lineolate on both surfaces ; petiole If in., puberulous. Spike (one 

 only seen) 2f in., puberulous; flowers ^ iu. apart. Calyx-segments \ in., linear, 

 puberulous. Corolla not seen. Capsule |-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 in 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 fc in., dense clothed with capitate hairs; 

 bracteoles 2, linear-subulate. Calyx 5-leaved, 2 lanceolate subulate, 1 broader 2-nerved 

 sub-bifid, 2 smaller. Corolla showy, pubescent without ; tube 1 in. filiform, limb of 

 5 subequal round lobes. Stamens 2 with oblong villous anthers, 2 sterile very short. 

 Style long, tip semi-bifid. Capsule oblong-ovoid, 4-seeded. Seeds brown, compressed, 

 ovate subrotuud, under a lens elegantly clothed with imbricated adpressed ferruginous 

 scales. 



XXVII. CODONACANTKUS, Nees. 



Corolla small ventricose nearly from the base. Otherwise as Erav- 

 iliemum. 



The solitary species differs from Eranthemum indicum in its very small flowers ; 

 from E. leptanthus in its ventricose corolla. 



C. pauciflorus, Nees in 'DC. Prodr. xi. 103; leaves elliptic 

 acuminate at both ends pubescent on the nerves beneath or glabrate,
