sepals ovato-acuminate or ovato-rotundate, subequal, 

 S lines long: corolla rufescent, narrow at the base. 



Travancore and Mergui. Specimens were com- 

 municated from the latter station by the late Mr. 

 Griffith. ^ 



1371. CuscuTA Arabica (Fresen. pL aeg.), stem 

 thread-like : capitula of flowers sessile ; each flower 

 sessile or pedicelled: calyx ^ line long, fleshy: 

 corolla a little longer than the calyx, 5-cleft; mar- 

 cescent round the base of the capsule; lobes 

 straight, acute : stamens sub-exserted ; scales of 

 the corolla scarcely conspicuous or wanting. — Stems 

 yellowish white : calyx white : stamens inserted 

 on the throat, short: stigmas subcapitate: capsule 

 globose, 4-sided. 



Scind. Stocks. Parasitic on Jlmaranthiis olerace- 



USf &c.

1372. CuscuTA HTALmA (Roth), peduncles about 

 3-flowered ; flowers pedicelled : corolla hyaline, 

 longer than the calyx, lacineae lanceolate, — Stems 

 filiform, corolla 4-5 cleft, about twice the size of 

 the calyx: stamens attached to the throat of the 

 corolla with over-lying scales : scales fimbriated 

 on the margin: flowers whitish or pale yellow: 

 capsule globose. 



Palamcottah, on stems of Amaranfhus okraceus. 

 This form seems intermediate between Roxburgh's 

 C. sulcata and Roth's C.hyalina; it does not agree 

 with the description of either, but I prefer referring 

 it to the latter, as the principal point of difference 

 consists in the number of parts of the flower, 

 quaternary in his, quinary in mine, most likely 

 accidental. In other respects may seem to agree 

 very well. 



1373. CuscuTA Chinensis (Lam.), stems slender, 

 filiform: fascicles of flowers lateral, glomerulatate 

 or sometimes loosely panicled, each flower minute, 

 sessile or subsessile: calyx S-lobed, lobes ovate 

 oblong obtuse, ^ a line long: corolla campanulate, 

 scarcely twice the length of the calyx, 5-lobed: 

 minute penicellate scales inserted on the throat 



Ceylon, parasitic on Vinea rosea. Apparently a 

 widely distributed and rather variable species, as 

 it has several names. 



"Fascicles of flowers squamate at the base : calyx 

 scariose shining, with the lobes angled (Lam.), car- 

 noso sulcated (Roxb.): lobes of the corolla often re- 

 flexed, sometimes lanceolato-ovate, sometimes linear 

 acute: stamens exserted, inserted on the throat by a 

 short filament: styles straight or slightly diverging, 

 withering on the apex of the capsule: capsule 

 round: corolla deciduous not marcescent round the 

 capsule." Ch. in D. C. 



1374. IpoMiEA BRACTEATA (R. W.), hcrbaceous, 

 twining, everywhere clothed with long pubescence: 

 leaves long petioled, round cordate mucronate : 

 peduncles about the length of the petiols, cymosely 

 3-flowered: flowers sessile, small, the lateral ones, 

 each furnished with 3 ovate cordate^ obtuse, folia- 



glabrous, reticulated beneath with redish veins, long 

 petioled: peduncles many-flowered, spicately raci- 

 mose, as long as the petiols; pedicels afterwards 

 thickening, black: sepals about ^ an inch long, 

 ovato-orbicular, equal, glabrous : seeds silky. 



Eastern slopes of the Neilgherries. 



A large and very handsome species: flowers 

 white, tinged with rose, purplish near the bottom 

 of the tube. The only figure yet published, so 

 far as I am aware, of this species is Rheede's, 

 and that seems so far characteristic as to leave 

 but little room to doubt that this is his plant. I 

 do not feel equally sure of its being identical 

 with the Timour one from which M. Choisy's char- 

 acter is drawn. 



1376. PoRANA RACEMOSA (Roxb.), hcrbaceous, 

 twining, glabrous or pubescent: leaves cordate 

 acuminate, cauline ones long petioled, floral ones 

 (bracts?) sessile, stem clasping: panicles racemose, 

 loose, flowers long pedicelled: sepals ciliate, at 

 first acute, afterwards enlarging: corolla tubular 

 campanulate, limb 5-parted, spreading: ovary 2- 

 seeded: style filiform: stigma capitate: seed soli- 

 tary: embryo contorted. 



^ Eastern slopes of the Neilgherries, between Bur- 

 liar and Coonoor* 



There seems little room to doubt that this plant 

 is identical with the Nepaul one, so far at least 

 as can be made out from description and specific 

 character. While examining it, I was led to scru- 

 tinise the characters of the genus more closely 

 than when publishing my figure of Parana volubihif 

 and very unexpectedly found that that plant, so 

 far as the characters derived from the style^ stig- 

 mas^ and ovary show, is a genuine species of the 

 more modern genus, Breweria, as a comparison of 

 the analysis of that figure (No. 347), which I have 

 again verified, with those of the accompanying 

 figure, No. 1370, of Brtweria Roxburghiiy will at 

 once show. This fact, if rigidly followed to its 

 consequences, must give rise to a troublesome al- 

 teration of names and a great addition to an 

 already abundant list of synonyms. Parana vohi- 

 bilia of Burman being the type of the genus, and 

 minutely according in structure with Brown's BreW' 

 eriay it necessarily results that it is equally the 

 type of that genus, consequently all the species 

 of the latter, under the law of priority, must be 

 referred to the former, thereby reducing the genus 

 Breweria. This alteration will, I presume, have 

 the effect of restoring Sweet's genus Dtnetus, es- 

 tablished for the reception of Porana racemosa and 

 P. paniculata* 



These remarks are based on the supposition 

 that Choisy is correct in referring my figure No. 

 347 to Porana volubUisj a point which I cannot 

 verify for myself by comparison with Burman's 

 figure, my copy being imperfect and wanting that 

 plate (No. 21). My plant certainly corresponds, in 

 every particular but one, with Roxburgh's descrip- 

 tion, namely, in having a 2- not 1-celled ovary, 

 and both correspond with Burman's description, so
