The genus Wallrothia was separated by Roth from 

 Vitex, on what always appeared to me very insuffi- 

 cient grounds, but being adopted by all subsequent 

 writers I, contrary to my own judgment, followed in 

 the train. M* J* C. Schauer, in his revision of the 

 order, has reduced the genus and restored the 

 species to Vitex^ a course which I have much 

 pleasure in following, the differences being of 

 specific rather than generic value, 



1468. Premna tomentosa ( Willd.), ramuli, young 

 leaves and cymes every where tomentose: leaves 

 petioled, ovate or ovate oblong, long, acuminate, 

 entire, venoso-rugous, stellato-pubescent on both

 plant he figures and describes as identical with 

 Rheede's Hort. Mai. 1 tab. 41, but as having no 

 affinity with Roxburgh's Cor. Plants, tab. 246. As 

 I have not seen either his figure or description, and 

 have only portions of Roxburgh's and Rheede's 

 figures, copied from the originals, not the entire 

 plates to compare, I am not in a position to offer an 

 opinion on Sir William's views, but on comparing 

 my specimens with Roxburgh's description, can see 

 no reason to doubt their belonging to the same 

 species, though there be considerable discrepancy 

 between their leaves and those of Roxburgh's plant, 

 as shown in his plate. The differences however are

1469. Premna integrifolia (Linn, P. serrati- 

 folia, Lin. Schauer), arboreous, the trunk and older 

 branches armed with opposite spines; unarmed 

 ranauli, panicles and petiols pubescent: leaves short, 

 petioled, ovate or oval, shortly and obtusely acumi- 

 nate, rounded towards the base, entire, or crenato- 

 dentate, the adult ones glabrous on both sides, 



slight differences in the outline of the foliage can 

 scarcely be admitted as of itself affording a suffi- 

 cient specific mark.

1471. Clerodendron infortujvatum (Linn), ra- 

 muli tetragonous, and like the branches of the pani- 

 cles, petiols, and nerves of the leaves, whitish, 

 strigoso-tomentose: leaves long, petioled, roundish 

 or ovato-cordate, or the upper ones ovate, or even 

 attenuated at the base, not at all cordate, entire or 



shining above, dull, opaque beneath: panicles ter- shortly acuminato-dentate, strigoso-hirtellate on both

calyx. Schauer in D. C- under P, serratifolia. 



A small tree, not unfirequently met with on the 

 plains of India, especially towards the coasts. The 

 flowers which, but for their mass, forming large 

 corymbs, somewhat resembling the Elder, would be 

 sufficiently inconspicuous, exhale a heavy, disagree- 

 able smell, and with their pedicels, are slightly be- 

 dewed with a viscid secretion. 



Linnaeus made two species of this tree, the one 

 "P. foliis integerrimis," the other "P. foliis serratis.*' 

 The figure represents the former of these, but as 

 both seem to form but one species, I have not hesi- 

 tated to adopt Schauer's definition of the latter for 

 my plant, as it is so minutely applicable that one 

 might almost suppose that the specimen from which 

 it was taken, was gathered from the same tree with 

 the one represented. 



1470. Gmelina arborea (Roxb.), arboreous, un- 

 armed, rai^i and young leaves covered with a 

 greyish, powdery tomentum: leaves long, petioled, 



squamato-glandulose, 5-parted; segments lanceolate, 

 slenderly acuminate : corolla strigoso-villous, and 

 glanduloso-punctuate, many times longer than the 

 tube of the calyx; segments of the limb sub-ungui- 

 culate, sub-secund, 3 times shorter than the tube. 



Frequent in forests and sub-alpine jungles, but 

 also occurs at a great elevation on the Neilgherries. 

 Flowers white, berries purple. Generally to be met 



during 



plants 



1472. Cjlerodendron serratum (Sprengel), ra- 

 muli quadrangular, furrowed, and with the leaves 

 glabrous: leaves opposite or ternate, chartaceous, 

 short, petioled, ovate, oblong or even lanceolate, 

 cuneato-attenuate, entire at the base, acuminate, 

 remotely mucronato-serrato-dentate, somewhat shin- 

 ing above, pale beneath: panicles terminal, raceme- 

 like, whitish, from mealy pubescence: lower bract, 

 and bracteoles foliaceous, pale, membranaceous, 

 acuminate, bracts ovate, roundish, bracteoles lance- 



cordate or somewhat produced and acute at the olate: cymes two or three times trifid, loose: calyx 



base, acuminate, the adult ones glabrous above, cup-shaped, sub-truncated, very shortly 5-toothed: 



greyish tomentose beneath, with 2-4 glands at the tube of the corolla cylindrical, more than twice the 



base: panicles tomentose, axillary and terminal length of the calyx, 

 raceme-like; cymules decussate, trichotomous, few- 

 flowered: bracts lanceolate, deciduous: the acutely 



dentate calyx, eglandulose. 



A small tree, not unfrequent in the Paulghaut 

 jungles, and generally distributed in Malabar. 



The drawing was made from a specimen obtained 

 near Koonoor on the Neilgherries, and seems to cor- 

 respond sufficiently with both Roxburgh's figure and 

 description. I advert to this, as I understand Sir W. 

 Hooker has made a new species under the name of 

 G. Rheediij of what I suspect can at best be viewed 



A rather common plant, in shady woods and sub- 

 alpine jungles. Abundant on the Neilgherries and 

 there, growing in open pasture ground, a very con- 

 spicuous object 



The leaves are deep green, the flowers blue, 

 deeper at the apex, becoming paler downwards, 

 sometimes wifli a considerable tinge of rose, which 

 adds greatly to the beauty of this already handsome 

 plant. The shrub varies from one to six feet in 

 height, rarely so low as the first, or higher than 

 the last
