1348, DiDYaiocARPUS Rottleriana (Wall.), stem- 

 less, incanous: leaves spathulato-obovate, crenate, 

 densely clothed on both sides with white tomen- 

 tum: scapes erect, hairy, subcorymbose, drooping 

 at the apex: flowers smallish, corolla subinfundi- 

 buliform, 5-lobed: capsule 



villous : calyx deciduous, 5-parted, lobes lanceolate 

 pilose: corolla tubular, ventricose beneath, con- 

 tracted at the throat: stigma scarcely dilated: 

 capsule long slender, pubescent, dehiscing on one 



side. 



Courtallum, flowering August and September.

includes two of the following species. I am un- 

 certain whether I am correct in appropriating the 

 name to this or the following species, but I 

 apprehend, that of the two, this will be found to 

 consort best with the character though by much 

 the rarer plant Its rarity indeed makes me doubt 

 whether this is the true species ; the other is much 

 more common. Brown in his synopsis of the genus 

 lays considerable stress on the circumstance of 

 the capsule, in the first instance, splitting along 

 one side and the valves long cohering on the 

 other, which he considers of sufficient moment 

 to distinguish the peninsular species from all the 

 others he defines, but I find it common to all 

 the peninsular species I have examined, except 

 the present, the mature capsule of which I have 

 not seen, but observe the same tendency in a 

 half-grown one. 



1349. DiDYMOCARPUS TOMENTOSA (R. W.), leaves 

 obovato-spathulate doubly crenate, reticulately dull 

 whitish toraentose above, densely ferrugeneo-to- 

 mentose or woolly beneath: scapes erect, dicho- 

 tomously cymose, many flowered, hairy above: 

 calyx 5-cleft, lobes linear obtuse, clothed with 

 glandular hairs: corolla subcampanulate 5-cleft, 

 lobes suborbicular : fertile stamens shorter than 

 the tube: ovary about the length of the calyx: 

 stigma dilated: capsule cylindrical about I4 inch 

 long, pointed, hairy, splitting along one side only. 



— Flowers bluish purple. . 



Alpine situations, forming dense patches m moist 

 clefts of rocks, &c. The specimen figured was 

 gathered at Kaitie falls on the Neilghernes, m 

 February. I have since received many speci- 

 mens from hiUs near Coimbatore, and have otten 

 met with it in similar situations. 



1350. DiDYMOCARPUS LYRATA (R. W.), stemless : 

 leaves large, lyrate, finely crenate, pubescenti- 

 pilose on both sides, especially on the veins: 

 scapes erect shorter than the leaves, dichotomous ; 

 branches racemose, hairy: calyx 5-parted, lobes 

 lanceolsfe acute, pilose: corolla tubular, curved, 

 somewhkt ventricose beneath, equally 5-lobed: 

 capsule terete or slightly compressed, 8—10 lines 

 long, hairy; splitting along one side only. 



CourtallJm, in moist shady places, flowering 



August and September. . 



This appears a very distinct species, the large 

 lyrate pilose leaves and small flowers, at once 

 distinguishes this from all the others of this sec- 

 tion of the genus. 



1351. DiDYMOCARPUS OVALIFOLIA (R. W.), IcaVCS 



petioled, oval, obtuse at both ends, "ena o-serrate 

 perminerved, slightly pilose on both sides, more 

 densely so on the veins beneath: scapes about 

 the length of the leaves umbellately 3-6 flowered, 



Jerdonia. (R. W.) 



Calyx 5-parted, lobes narrow lanceolate. Cor- 

 olla subinfundibuliform, 4-lobed, the posterior one 

 larger emarginate. Stamens 4, all fertile. Filaments 

 dilated, anterior pair broader, furnished with a 

 broad descending tooth. Anthers 2-celled, and, 

 cohering at the apex, form a disk-like crown over 

 the stigma; cells divaricating. Ovary embraced 

 at the base by a cup-shaped disk, 1-celled, with 

 4 parietal placentae, 2 at each side. Ovules attach- 

 ed to a slender filiform podosperm. Style short. 

 Stigma dilated, peltate, concealed under thg co- 

 hering anthers. Capsule '-. 



A small, herbaceous, stemless plant. Leaves pe- 

 tioled, oval obtuse at both ends or slightly cordate 

 at the base; the younger ones pubescent all over, 

 the veins and margins only of the older ones 

 clothed with long redish hairs. Scapes erect, fih- 

 form, longer than the leaves: pedicels short, sub- 

 umbellate, surrounded with subulate pilose bracts. 

 Calyx fringed with moniliform hairs, lobes narrow 

 lanceolate or subulate. Corolla infundibuliform, 

 limb somewhat bilabiate h Filaments incurved 

 at the apex, dilated below, the anterior pair 



pubescent. 



I am indebted to Mr. Jerdon for my specimens 

 of this interesting little plant which, as forming the 

 type of a new genus, I have much pleasure in 

 dedicating to the discoverer; an honor well merit- 

 ed by his extensive researches in all branches 01 

 organic natural history. Though Botany is the 

 last to which he has given his attention it has 

 already reaped considerable advantage from his 

 energetic application to the study of plants. The 

 affinities of this genus in the order are still some- 

 what obscure, partly owing to the unusual struc- 

 ture of the ovary, and partty to the want ot 

 mature capsules. The stamens, too, are peculiar 

 as regards the filaments and anthers, but especi- 

 ally the latter, which are more in accordance witli 

 those of Bignoniace(z than CyrtandracerB, the order 

 to which I for the present refer it, more on ac- 

 count of habit than structure, as both the anthers 

 and ovary are opposed to that location.
