ACANTHACEAE.

lobe as long, broadly obovate-oblong, with 2 small lobes at 

 base. A very distinct species ; the lower third of the leaf resembles 

 a long, winged petiole. 



Hydromestus, DC, " Prod." xi. 291 ; (fig. "Bot. Mag." t. 4556, as 

 maculatus). — Mexico. Branches purplish ; leaves glossy, elliptic 

 oblong, 9-12 inches by 2-3 inches ; spike terminal and axillary, 

 4 inches long, narrow; bracts 1 inch long, carinate, broad - 

 ovate to obovate, sharply pointed, slightly serrate towards the apex, 

 subcoriaceous, closely imbricate like the scales of a cone, in 

 4 series ; flowers large, yellow, H inch, the curved tube well 

 exserted beyond the bracts, funnel-shaped upwards ; lobes large, 

 spreading. Syn. A. maculatus, A. glabrata, Strobilorhachis pris- 

 maticus, Lagochilium Hydromestus — see Hemsley, " Biol. Cent. 

 Amer. Bot." 2. 512. 



LeqpoZdw=squarrosa var. Leopoldii. 



Liboniana, Lindley (fig. "Bot. Mag." t. 5463). — Tropical America. 

 Leaves white-banded, about 9 inches long, suddenly acuminate, 

 entire, petioles 2-3 inches long ; spike terminal, about 6 inches 

 long, narrow ; bracts imbricate in 4 rows, bright orange, about 

 H inch long, broad, ovate, the base concave; flowers small, 

 yellow, red at the apex, nearly hidden in the bracts. Much in the 

 way of variegata. 



maeedoiana, Lind. & Rod. (fig. "111. Hort." xxxiii. (1885), t. 583). 

 — Brazil. Leaves elliptic-ovate, obtuse, 4^ by 2J inches, dark 

 green above, the midrib and veins margined with pale whitish- 

 green, beneath purple ; flowers not seen. 



Macleayi, sp. n. — Glabrous. Leaves decussately opposite, green 

 on both sides, 1-2 inches, lower ones up to 3 inches, long, 

 ovate-elliptic, gradually acute at apex, margins entire, attenuated 

 at the base into a short petiole, veins obscure above, an irregular 

 zigzag white band down the midrib, under surface paler, veins 

 prominent ; spike terminal, strobiliform, cone-like, short, oval, 

 somewhat 4-sided, 1^-2 inches long ; bracts rather closely 

 packed, J inch long, green below, brown upwards, serrated towards 

 the apex and then running into a long apiculus ; calyx small, 

 segments linear-filiform, whitish ; corolla orange-scarlet, nearly 

 2 inches long, the lower cylindric portion of the tube f inch, 

 then curved and gradually expanding upwards, 2-lipped, upper 

 lip shortly bifid and arched over the stamens, lower lip deeply 

 3-cleft, spreading and recurved. 



A pretty, free- flowering species. I received this years ago from 

 Sir George Macleay as A. punctata (there is a dried specimen 

 unnamed from his garden in the Kew Herbarium). I have also 

 met with it in stoves under the name of squamosa. It, however, 

 has nothing to do with either of these species (which both have 

 yellow flowers), and as it appears to be undescribed, I have given 

 a Latin description.* Its small leaves readily distinguish it from 

 any other species.

 petiolatis, oblongo-acutis, basi in petiolum angustatis, integemmis, secus costam
