As my collection is rather rich in species of this 

 order, I might have added considerably to the num- 

 ber of plates devoted to its illustration, but now that 

 the work is drawing to a close, this being the conclud- 

 ing volume, I felt desirous of aiding the researches 

 of those Lidian Botanists, less favourably situated 

 than I am for determining them, by giving illustrations 

 of as many genera of other orders as my now limited 

 space will permit. 



1818. C amphora officinarum (Bauhin Pinax), 

 leaves triplmerved, shining above ; axils of the veins 

 glanduliferous ; corymbs naked : flowers externally 

 glabrous- 



I only know this plant from description, and the 

 figure copied from Roxburgh's drawing for which 

 I am indebted to the kmdness of Dr. Wallich, whUe 

 superintendent of the Calcutta Botanical Garden. 



1819- Apollonias Aenotth (Nees ab Esenbeck), 



glabrous : leaves oblong, exquisitely acuminate at 



both ends, smooth. 

 CourtaJlum, flowering July and August, 

 This is the only Indian species of the gepus known 



to Professor Nees. This genus is distinguished from 



the following by having 2- not 4-celled anthers. 



1821. Phoebe i^ANCEoiiATA (Nees, Lauras lanceo- 

 laria^ Roxb.), leaves oblong lanceolate, or lanceolate, 

 with a long acumination at both ends : finely pube- 

 scent beneath : corymbs glabrous, spreading : the 

 interior stamens hairy. 



The figure is copied from Roxburgh's drawing, for 

 which with aU the others marked " Roxburgliianae," 

 from the same collection, I am indebted to the kind- 



WalUch 



the many favours of 

 hun. The tree is a

VIIXOSA 



W., Lauras 



Eoxb. Fl. Ind. 2. 310), arboreous ; leaves alternate, 

 petioled lanceolar, 1 -nerved : panicles axillary, and 

 several round the base of the young downy shoots, 

 villous : berries spherical, of tlie size and appearance 

 of a black currant. 



A large tree, native of Chittagong. This species 

 does not appear to have been seen by Nees, as it is 

 not noticed in his " Systema;" it seems, however, to 

 be a species of the genus. 



1823* Persea gratissima (Gaert.), leaves ovate, 

 ovate oblong, or obovate, somewhat acute at both 



1820. Phoebe pakiculata (Nees), leaves obo- ends, reticulate, pubescent l^neath, p-nerved (novem 



vato-elliptic, acute^ at both ends, reticulate beneath, 

 the midrib, ramuli, and loose dichotomous panicles 

 rusty, tomentose : lobes of the perianth, and the fruit 



ovate. 



Neilgherries, &c. I have specimens from several 

 stations, those from which the drawing was made 

 were gathered in woods about Ootacamund, where 

 the tree, a considerable one, is not uncommon. The 

 under surface of the leaves are rather closely netted 

 with thickish veins, and of a deep rusty brown colour* 



costatis), glaucous : lobes of the perianth about equal, 

 oblong : ovary glabrous : berry large pear-shaped. 



The drawing was taken from a cultivated specimen 

 and introduced for the purpose of illustrating the 

 genus- The fruit acquires a much greater size than 

 those in the plate. They are known under the cu- 

 rious English name of Alligator pear. The tree is a 

 moderate sized one, very branchy. The genus Persea 

 is a large one, but seems only to include two Asiatic 

 species, and both of these from the Eastern Islands.
