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 T. Jambosella, and it is 

 -alsoWallich's 8446. 



60. DICHILANTHE, Thmtitcs. 



Trees with stout spreading branches, and resinous buds and nodes. Leaves 

 rigid, elliptic-lanceolate, acuminate ; stipules connate into a short intra-petiolar 

 ring. Floivers small, sessile on a terminal sessile or peduncled orbicular recep- 

 tacle formed of connate bracts. Calyx-tube elongate, curved ; limb obliquely 

 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. DiaJt 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 

 incurved, 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 1^-2 in., glossy, red-brown -when dry, finely 

 reticulate, very coriaceous, narrowed into the stout short petiole. Peduncles very 

 short; heads ^-| in. diam. Calyx-lobes % in. Corolla f-l in. long, purplish. The 

 irregular flower is very anomalous, and resembles that of Capri foliacea. 



TRIBE VIII. KNOXXXUS. 

 61. K.NOXIA, Linn. 



Erect herbs or undershrubs ; sterns 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. DISTRIB. Species 8 

 or 9, Indian, Malayan and Australian. 



The synonymy of the Indian species is very confused, owing to the incomplete 

 descriptions of the earlier authors. Some of the citations of De Candolle and Kox- 

 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 based 

 perforation ; mericarps closely united, rarely separating.
