396 oix. ACANTHACKB. (C. B. Clarke.) [Ebermaiera. 



Leaves 2 by f in., obtuse, base attenuate, slightly viscous-pnbescent or glabrate, entire 

 or sinuate ; petiole J in. Spikes 2-6 in. ; lowest bracts altogether leaf-like (whence 

 T. Anderson says " flowers solitary axUlary ") ; tip of the spike often dense with 

 short bracts resembling the spike of neighbouring species ; bracteoles linear, obtuse, 

 shorter than the calyx. Sepals 4 subsimilar, i in., linear-subnlate, sparsely glandu- 

 lar-hairy ; the fifth longer, much broader, linear-oblong, obtuse. Corolla straight, 

 slightly pubescent without, purplish with rose or yellow stripes. Anther-eeUs 

 muticous or minutely mucronate at base. . Capsule I in. — Described from Nees' type 

 specimen j Wight's figure is taken from a form having a much denser more glandular- 

 pubescent spike. The Australian species referred here by T. Anderson and Bentham 

 differs in its hairy ovary and capsule, and many other minute points j but it might be 

 better to unite it, and make a wholesale reduction of species here. 



Vae. spatulata ; leaves very spathulate, spikes denser only a few of the lowest 

 elongate, calyx and bracteoles very glandular-hairy, corolla scarcely i in. Adenosma 

 spatulatum, Slume Sijd. 757. Ebermaiera spatulata, Sasslc. ; Nees in DC. Prodr. 

 xi. 74, partly ?. — Pegu ; Kwz. Tenasserim ; Seddome. Bengal ; Pnbna, Clarhe. 

 — Distrib. Java. — Growing in lice-swamps; stems erect, thick, quadrangular or 

 striate ; many or nearly all the leaves alternate. — Sbermaiera spatulata, Nees, is 

 described from a Riilippine plant of Cuming's, which widely differs from Kurz's Pegu 

 specimens. 



2. E. polybotrya, Nees in DC. Prodr ^m. 74 ; stems erect adpressedly 

 grey-pubescent upwards, leaves elliptic subobtuse at botb ends, spikes 

 cylindric not lax downwards, bracts narrowly oblong scarcely exceeding the 

 calyx, corolla 5 in. 



Bengal ; frequent in Terai swamps in Sikkim and Silhet, J. D. S., &c. MOTJL- 

 MEIN and MeeOUI ; Oriffith. 



Stems 6-8 in., often branched from the base. Ijeaves all opposite, even at the 



linear, subobtuse j the fifth rather longer, much broader, oblong, obtuse. Corolla, 

 stamens, and capsule neaVly as of JS. glauca. 



3. E. Iiumilis, Nees in Wall. PI. As. JBar.iii^ 80, and in DC. Prodr. 

 xi. 74; stem erect branched adpressed wMte-pubescMit upwards, leaves 

 opposite subsessile narrowly elliptic, beads terminal small globose, bracts 

 oblong sessile hardly so long as the calyx, corolla J in. and upwards. Wall. 

 Cat. 7148 ; T. Anders, in Joum. Linn. Soe. ix. 450. 



BuEMA ; Prome Hills, Wallich. 



Stem 6-8' in., branched from near the base ; branches ascending, shorter than the 

 central stem. Leaves- \\ by i in.., obtusely rhomboid at both ends, nearly glabrous, 

 adpressedly white-pubescent on the nerves beneath ; petiole hardly -^ in. diam. Sends 

 sessile, J-| in. diam. ; bracts and bracteoles J in. Sepals, 4 linear, subobtuse ; the 

 fifth slightly larger, oblong obtuse. — Nearly allied to E. polybotrya, but the heads 

 are not elongate cylindriC) the bracteoles and sepals are less acute, the corolla is 

 larger. 



4. Tt. slntlnosa, Wall. Cat. 9087 ; stem trailing rooting pubescent, 

 leaves elliptic, base attenuate, heads subspherical on short branches and 

 quasi-axillary, bracts elliptic sessile hardly so long as the calyx, coroUa J in. 

 Ebermaiera sp^, Wall. Cat. 9085. B. glauca, T. Anders, in Joum. Linn. 

 Soc. ix. 450, in great part. 



Centeai India, N.W. Provinces, and Ben&ai,, frequent ; Moradabad, Thom- 

 son ; Behar, J. D. S. ; Bundelcund, Sdgeworth ; Silhet, Wallich, &c. 



Stems numerous, 12-18 in. ; nodes in the trailing branches distant. Leaves all 

 (or nearly all)> opposite, 1^ by | in., subobtuse, entire, minutely pubescent or glabrous ;
