432 CIX. ACANTHACEX. (C. B. Clarke.) [Strobilanthes. 
A shrub, 2-5 ft. Leaves 4 by 18 in. ; nerves 7-8 pair, not conspicuously parallel; 
petiole 3 in. Spikes 3-8 in., axillary, simple or compound, and running into terminal 
panicles; flowers opposite, lowest pair usually distant; bracts À in., elliptic or oblong, 
attenuated upwards ; bracteoles 1-lin., narrow. Calyx viscidly hairy, teeth lanceo- 
late; calyx in fruit enlarged often 3 in. or more, split to the base into lanceolate 
segments. Corolla 1} in., densely pubescent without; linear-base of the tube 4 in., 
very narrow, ventricose portion 4 by 4 in., oblique, lobes ovate. Filaments glabrous 
except nearthe base ; anthers large, pendulous, subexserted. Capsule } in., 4-seeded. 
Seeds more than j in., ovoid, thinning towards the apex, smooth, hairless. 
Var. microphyllus, Nees in DC. Prodr. xi. 104; leaves 4-1} in., spikes very weak 
few.fld.—Ceylon.—The type specimen of this has no fruit; but Walker, n. 122, has 
similar small leaves and fruit exactly as of S. viscosus type. . 
Var. digitalis; bracts abbreviated, spikes elongate slender, minutely deciduously 
cinereous- woolly not hairy nor viscous. Endopogon digitalis, Nees in DC. Prodr. xi. 
104 (sp.).—Ceylon ; Walker.—This is possibly nearer S. ezareolatus, but the example 
is in young flower. . 
Var. arguta ; leaves more rigid more acutely (though minutely) toothed, spikes 
dense, bracts j in. oblong imbricate, calyx minutely cinereous-woolly. Endopogon 
argutus, Nees in DC. Prodr. xi. 104.—Ceylon; Gardner.—The examples referred 
here by Nees (probably on the characters of the leaves) having fulvous viscid hairy 
spikes seem nearer S. viscosus, T. Anders. type. 
.6. S. stenodon, Clarke; glabrous, leaves ovate acuminate crenate, 
spikes linear scarcely interrupted, bracts short obovate, calyx divided half- 
way down, corolla-lobes narrowly oblong. 
CEYLON ; Matelle East, Beckett, Thwaites, C. P. n. 3874. . . 
Leaves 4} by 2 in., shortly narrowed into the petiole ; nerves 8 pair; petiole 1} in.; 
leaves white underneath in Beddome’s Ceylon specimen. Spikes 2-5 in., axillary, 
simple or compound, running into terminal panicles; bracts } in.; bracteoles ł in., 
narrowly oblong. Calyx glabrous, teeth lanceolate. Corolla glabrous in bud, 
white-hairy within ; cylindric base } in., very narrow ; ventricose tube 4 in. long and 
broad; lobes 4-3 in. Anthers exserted, pendulous. Ovules 2 in each cell. Capsule 
not seen.—A remarkable plant with the habit, inflorescence and bracts of Stenost- 
phonium Russellianum ; the narrow lobes of the corolla are unlike any neighbouring 
species or genus. 
. 7. S. exareolatus, Clarke; leaves elliptic acuminate at both ends 
slightly undulate crenate glabrous, spikes linear lax hairy, calyx narrow 
overtopping the bracts divided less than half-way down. S. consanguineus, 
T. Anders. in Thwaites Enum. 226, and in Journ Linn, Soc. ix. 465, partly. 
Stenosiphonium diandrum, Nees in DC. Prodr. xi. 105, not of Wight. 
Endopogon consanguineus, Nees l. c. as to the Ceylon material. 
CEYLON, alt. 3000 ft.; Walker. : 
A shrub. Leaves 3} by 1} in.; nerves 6 pair; petiole 2 in. Spikes 2-4 in., 
running into terminal panicles; bracts 4-4 in., ovate or oblong; bracteoles 3 in., 
narrow, Calyx (in flower) 1-4 in., teeth sublinear ; in fruit enlarged. Corolla j in, 
resembling that of S. viscosus but smaller. Capsule | in., 4-seeded. Seeds scarcely 
T in., ellipsoid, smooth, hairless, without lateral areoles.— Near S. viscosus, differing 
by the short bracts, narrow cylindric calyx, smaller flowers and much smaller seeds. 
As to the synonyms, tbe type specimens of Nees and T. Anderson, written on by their 
own hands, are preserved at Kew. 
AR. densa ; spikes denser, bracts elliptic imbricate often as long as the calyx.— 
Ceylon, alt. 2-6000 ft. ; Thwaites, n. 2002 chiefly, &c. 
8. S. rhytisperma, Clarke ; leaves elliptic acuminate at both ends 
denticulate thinly white-cottony beneath, spikes linear uninterrupted 
glabrous, bracts lanceolate about equalling the calyx. S. hypoleucus, T. 
Anders. in Thwaites Enum. 226, not Endopogon hypoleucus, Nees.
