EXPLANATION OF PLATES 



VOL. IV.— PART IV, 



only the apex of the filaments, of the longer pair of 

 stamens, furnished with a dense tuft of hairs, which 

 Nees has, it appears to me, mistaken for the lower 



cell of the anther, as he certainly has done in the 

 case of Erianthera. 



1505. DiPTERACANTHus PA.TULUS (Nees), stem 

 erect ; leaves ovate-oval or oval-oblong, obtuse, and, 

 like the ramuli, more or less whitish-puberulous : 

 flowers fasciculato-ternate or quinate (or solitary), 

 short pedicelled: bracteoles oval or oblong, longer 

 than the calyx. — Capsule glabrous, compressed and 

 sterile below the middle, about 12-seeded. Seed 

 convex, glabrous on the outside, somewhat concave 

 and puberulous on the inner face. Corolla pale blue. 

 In flower at all seasons, when there happens to be 

 rainy weather.

R, W- Ic. 873), leaves ovate, dentate, naked beneath : among rubbish and about neglected hedge rows, &c. 



bracts rhomboid, obtuse, cuspidate, as long as the The seed in this plate is represented much too hairy. 



1502. Stenosiphonium diandrum (Nees), leaves 

 ovate, crenato-dentate, glabrous: bracts oblong, 

 somewhat obtuse, and, like the calyx, glanduloso- 

 hispid: flower solitary, diandrous: filaments hairy 



at the base. 



Courtallum; flowering July and August. Nees' 

 specimens of this species are from Ceylon, hence a 

 doubt exists as to this being identical with his. He 

 remarks, "the species fluctuates between Endopogon 

 and Stenosiphonium, but the calyx is scarcely divided 

 down to the middle. Terminal spikes trifid ; the 

 axillary ones leafy at the base ; smaller leaves 

 roundish. Approaches, S. confertum." 



In habit it very nearly approaches S. confertum, 

 from which it is kept distinct by its diandrous 

 flowers. 



calyx. 



This I believe is the true plant. The one figured, 



No. 873, under the same name is, I now find, S. con- 

 fertum^ a species not published at the time that plate 

 was named. I therefore request the reader to sub- 

 stitute the following, for the name and character 

 there given. 



873. Stenosiphonium confertum (Nees, S. Rus- 

 sellianum, R. W- Ic), leaves broad ovate, dentate, 

 naked beneath: bracts ovato-lanceolate or oblong, 

 obtusely accuminate (shorter than the calyx) and, 

 like the calyx, glanduloso-hirsute : flowers geminate 

 or temate. Nees, in DC. Prod. Pulney Mountains, 

 Neilgherries, &c. 



1504. Hemigraphis latebrosa (Nees), leaves 

 ovate, coarsely serrate: bracts ovate, lanceolate, as 

 long as the calyx.— The capitula or spikes, shortened 

 to the form of heads, furnished at the base with two 

 small sharply-serrated leaves, having a long, linear 

 margined petioL The lower pair of bracts a little 

 broader than the rest, no bracteols : lacinese of the 

 calyx Une«, ciliate and, like the bracts, 1-nerved, 

 the posterior one longer: anthers with one aresta at 

 the base, capsule two and half lines long, thm, 

 4-angled, six-seeded, from the base, shorter than the 



1506. AsTSTAsiA CoROMANDELiANA (Nces), Stem 

 ramous, branches diffuse ; leaves cordato-ovate, ovate, 

 or suborbicular; lineolato-rough above : racemes 

 axillary, long-secund, straight, calyx lobes acumi- 

 nate. — Corolla about an inch long, funnel-shaped, 

 yellow at the base. Capsule an inch long. 



Slopes of the Neilgherries at a considerable eleva- 

 tion. The species, however, is common all over the 

 country flowering during the rainy seasons. The 

 specimen represented does not present a character- 

 istic form of the plant ; and for some time I suppos- 

 ed it a new species, but the species being variable 

 I cannot find characters by which it can be kept 

 distinct. The flowers in the specimen were nearly 

 white, specked with reddish yellow spots: lilac is the 

 usual colour. 



1507. Leptacanthus Walkeri (Nees), panicle 

 densely glanduloso-villous : lobes of the perianth 

 linear-filiform, the upper one a little longer: cauline 

 leaves oval oblong, pubescent beneath ; floral ones, 

 at least the primaries, ovate, acuminate, small. — 

 Upper branches hairy, leaves with the petiol from 

 6 inches to a foot long 1^ to 3 inches broad, acumi- 

 nate or caudato-cuspidate, lacineae of the calyx nar- 

 row, very villous, the upper segment longer, straight: 



calyx. I have some doubts as to this being Nees' corol 9-10 lines long, cylindrical, ventricose, lobes of

The specimens represented are from the Neil- 

 gherries, where it flowered in great perfection during 



plant. A point I cannot now settle firom not haying 

 the specimen, quoted as belonging to my herbarium, 

 to compare. I may however remark that, if this be 

 really a Hemigraphis, of which I think there can 

 scarcely be a doubt, then Professor Nees has not 

 correctly observed the anthers. These he describes 

 in the following words, "antterae uniloculares, loculo 

 connective augusto carinato adnato; superiorum 

 fitaminum altero loculo in barbam loculo subjectum 

 converse ; inferiorum staminum altero loculo omnino 

 deficiente loculo perfecto basi cymbiformi mucro- 

 nato." All the anthers of my plant are 2-celled, and

 leaves unequal, elliptico-lanceolate, acuminate, acute- 

 ly serrated, glabrous on both sides: inflorescence 

 paniculato-spicate ; spikes sub-capitate, long pedi- 

 celled, drooping few- (above 2-) flowered, involucrate: 

 involucral leaves or bracts.^ lanceolate acute: lobes 

 of flie calyx long, ciliate at the apex : corolla infun-
