glabrous ovary, and pubescent corolla. It is this latter I have described as Finlay- 
sonianus; there is another specimen of it on the sheet with 7. Jambosella, and it ‘is 
also Wallich’s 8446. 
60. DICHILANTHE, /waites, 
Trees with stout spreading branches, and resinous buds and nodes. Leaves

funnel-shaped, persistent; lobes 5, rigid, with toothed interposed segments. 
Corolla silky, funnel-shaped, tube curved, throat villous; limb 2-lipped, upper 
lip 2-, lower 3-toothed, lobes valvate in bud. Stamens 5, anthers included, 
oblong. Disk elevated, crenulate. Ovary with 2 narrow cells; style elongate, 
stout, stigma exserted clavate 2-lobed ; ovules 1 pendulous in each cell, cylin- 
dric, funicle thickened. Fruit obovoid, gibbous, 2-celled, outer in each head 
ineurved, pericarp thick. Seeds cylindric, albumen fleshy; radicle superior.—

CEYLON; between Galle and Ratnapoora, alt. 1000 ft., Thwaites. 
A tree 30-40 ft. Leaves 4-6 by 13-2 in., glossy, red-brown when dry, finely 
reticulate, very coriaceous, narrowed into the stout short petiole. Peduncles very 
short; heads 5-3 in. diam. — Calya-lobes } in. Corolla 3-11 in. long, purplish.— The 
irregular flower is very anomalous, and resembles that of Caprifoliacee. 
Trist VIII. KNOXIEÆ. 
6l. KNOXIA, Linn. 
Erect herbs or undershrubs; stems terete or obtusely angled, with 2 lines 
of pubescence. Leaves opposite; stipules connate with the petiole into an 
entire or bristly sheath. Flowers dimorphous, pink or lilac, subsessile on the 
elongating branches of terminal cymes, rarely spicate. Calyx-tube ovoid or 
didymous; teeth 4, minute and subequal, or 1 or 2 elongate, persistent. Corolla- 
tube long, throat villous; lobes 4, valvate in bud with inflexed tips. Stamens 
4, inserted within the throat; anthers linear, exserted or included.- Ovary 2- 
celled; style filiform, stigma included or exserted 2-lobed; ovules 1 pendu- 
lous in each cell. Fruit very small, of 2 semi-terete or dorsally compressed 
indehiscent cocci. Seeds with a thickened funicle, testa membranous, albumen 
fleshy; embryo axile, cotyledons thin, radicle superior.—Dtsrrip. Species 5 
or 9, Indian, Malayan and Australian. 
The synonymy of the Indian species is very confused, owing to the incomple'o ` 
descriptions of the earlier authors. Some of the citations of De Candolle and Rox- 
burgh may be open to question. Roxburgh’s descriptions do not accord with his 
drawings. 
* Ripe fruit separating from the persistent subulate columella by a basal 
perforation; mericarps closely united, rarely separating.
