XXXIII. DIOTACANTHUS, Benth. 
Corolla-tube short, limb large ventricose 2-lipped. Otherwise as Phloga- 
canthus or Cystacanthus.—Species 2, S. Malabaria. 
1. D. grandis, Benth. in Gen. Pl. ii. 1101; glabrous, leaves large 
lanceolate or obovate-lanceolate, panicles axillary peduncled many-fid. 
mostly exceeding the leaves, corollacrimson. Phlogacanthus grandis, Bedd. 
lc. Pl. Ind. Or. t. 179. 
TINNEVELLY and TRAVANCORE, alt. 34000 ft. ; Beddome. 
A shrub, 8-12 ft. Leaves 7 by 23 in., attenuate at both ends, undulate, obscurely 
crenate ; nerves 12 pair; petiole 2 in. Peduncles 2—5 in., stout, compressed ; panicles 
often 4-8 in.; bracts at its divisions $ in, linear; proper bracts } in., linear. Sepals 
iin,linear. Corolla minutely pubescent, tube 4 in., limb 2 in. ; upper lip emargi- 
nate, lower shortly 3-lobed. Filaments as long as the corolla, stout, minutely 
scabrous. Style minutely pubescent, subentire. Capsule 1 by i-i in., 24-seeded. 
Seeds much compressed, orbicular in outline, minutely crisped-pubescent. 
.2. D. albiflorus, Benth. in Gen. Pl. ii. 1101 ; nearly glabrous, leaves 
elliptic acute at both ends, panicles axillary peduncled few-fld. shorter thun 
o leaves, corolla pure white. Phlogacanthus albiflorus, Bedd. Ic. PI. Ind. 
r. t. 180. 
S. TINNEVELLY, alt. 3-5000 ft., and near Courtallum, Beddome. . 
A shrub, 6-10 ft. Leaves 5 by 13 in., subentire; nerves 7 pair; petiole 1-1 in. 
Peduncles 1-2 in. slender; panicles 1-1} in., depressed corymbiform. Calyx, 
Corolla and capsule nearly as of D. grandis.—Beddome describes the filaments as 
“much dilated below, articulated near the apex, quite black above the articulation ;” 
this character being remarkable in the Acanthace@, Mr. Bentham refers to (Gen. PI. 
1. 1101) the articulation of the filaments. But in a prolonged examination of the 
Very filaments supplied by Beddome no articulation whatever has been made out by 
myself and Prof. Oliver. 
XXXIV. LEPIDAGATHIS, Willd. 
Herbs or undershrubs, with often pubescent bracts or leaves. Leaves 
entire or erenate-serrate. Flowers sessile, usually capitate, sometimes 
Opposite or solitary ; heads terminal or axillary, dense (rarely lax), usually 
sided, often fascicled; bracts usually larger than the calyx-segments, 
rarely small; bracteoles narrower than the bracts. Calyx deeply 5-lobed ; 
Segments unequal, the 2 anterior more or less connate (calyx 4-partite). 
orolla small (except in L. longifolia), tubular, suddenly ventricose in 
the middle, 2-lipped ; lower lip 3-lobed, patent, usually spotted. Stamens 
, didynamous ; anthers all 9-celled ; cells oblong, muticous, parallel, or 
Mne lower somewhat divergent. Stigma capitellate, minutely bifid or entire. 
"psule 2. or 4.seeded elongate conoid or oblong. Seeds compressed, 
ovate-oblong, or orbicular hairy.—Species 50 tropical, whereof 2 only 
are American. '

* bounds of British India.
