130 LXXV. RUBIACEJ:. (J. D. Hooker.) [Knoxia. 



NILGIIIRI and SUEVAGHKRRY HILLS, Wight, &c. 



Rigid ; stems 8-18 in., terete. Leaves 2-3 by |- in., rigidly coriaceous, pale brown 

 when dry, complicate ; stipules erect, triangular-lanceolate, often quite entire. Cyme- 

 branches puberulous or glabrous. Fruits apparently angled, somewhat laterally com- 

 pressed, shortly podicelled, as broad as long. 



5. K.. bracbycarpa, Br. in Wall. Cat. 821 j more or less pubescent, 

 stem with 2 lines of pubescence, leaves sessile linear-oblong obtuse, stipules 

 entire or 3- or more-cleft, cymes open or capitate, fruits short didymous trun-

An erect strict herb, 2-4 ft., internodes long; stem slender or robust; more or 

 less hairy or glabrate, with always 2 more or less distinct lines of pubescence. Leaves 

 2-4 by J f in., usually quite sessile and minutely pubescent on the margins and 

 nerves beneath, more rarely elsewhere, base acute or rounded, pubescence of midrib 

 continued down the stem ; stipules pubescent, upper often entire. Cymes, if branched, 

 main branches pubescent in 2 lines, the smaller puberulous; when capitate often 

 tomentose ; flowers small. Calyx-teeth very small, obtuse, one larger. Fruit as in 

 K. Wightiana. I suspect this to be Roxburgh's Sp. leevis; it is the only "interior of 

 Bengal" plant at all answering to his description and drawing, from which it differs 

 in the hairiness and large flowers. The Nipal and Bengal specimens have open 

 cymes, the Kumaon ones globose terminal and sessile axillary heads, like Hedyotis ; 

 the Pegu ones have long brachiate branches with trichotomous terminal peduncles 

 bearing capitate cymes at their ends. 



ft One or two calyx-lobes in fruit much elongate, subulate. 



6. K. plantag-inea, Wall. PL As. Ear. 27, t. 32; Cat. 818; hirsute,, 

 subscapose, leaves sessile linear-oblong obtuse or subacute, stipiilar bristles very 

 short or 0, flowers capitate, fruits racemose, uiericarps keeled with 1 or 2' 

 elongate calyx-teeth. DC. Prodr. iv. 570 ; Kurz in Journ As. Soc. 1877, ii. 138. 



PEG a at Prome, Wallich; rare and sporadic, Kurz. 



Rootstock thick, tortuous, woody, giving off short woody leafy branches, from 

 which the very slender simple flower-bearing stems arise. Leaves on the stem 3-5- 

 by 7f-f in. ; softly hairy on both surfaces, green when dry ; stipules usually reduced 

 to a truncate sheath. Flowering stems 10-16 in., softly hairy, each bearing one or 

 two very distant pairs of small leaves 1 in. long, apparently without stipules, sparingly 

 trichotomously branched at the tip, each branch bearing a head of flowers which 

 elongates into a spike or raceme of distant fruits several inches long. Calyx-teeth 

 subulate, one or two much elongate and exceeding the mericarps. Corolla % in. long, 

 pale blue. Fruit (in Wallich's figure) in., apparently flattened, with keeled meri- 

 carps, the elongated calyx-tooth often much exceeding the fruit. 



7. XL. zeylanica, Linn.-, DC. Prodr. iv. 569: glabrous or glabrate,. 

 leaves shortly petioled ovate or ovate- or oblong-lanceolate, stipules entire or 

 with nearly glabrous bristles, flowers capitate or spicate, fruits spicate, mericarps 

 dorsally rounded and keeled. JBurm. Fl. Ind. t. 13, f. 2 ; A. Rich, in Mem*

CEYLON ; common in the southern part of the island. . 



A small leafy rigid annual ? ; stem erect or ascending, and branches terete, smooth 

 and scabrid above. Leaves 1-2 by - ^ in., narrowed at both ends, obtuse or sub- 

 acute, margins recurved. Spikes and flowers glabrate or hispid, when fruiting some- 

 tnn?s 4 in. long and quite simple. Corolla-tube very slender. Fruit ^ in., broadly 

 ovoid, the long calyx-tooth equalling the mericarp, glabrous.
