gener, though certainly distinct, in this country, in a yet undescribed species in my herbarium. 
Of 5 species of Grewia found there, one is certainly identical with our G. villosa, which being 
supposed new, by the authors, has received from them the very appropriate name of G. 
corylifolia, The other four species, J am unable to identify, from description only, with any of 
our species of that most difficult genus. Of the Javanese species several are common to this 
country, and one or two perhaps to Senegambia, showing, that although limited in their range by 
latitude, they have a very extensive range of longitude. 
Proesrtizs and Uses. So much has been said under this head in the preceding orders of 
the class Columnifere, which all enjoy analogous properties, that but little is left to be said here. 
The Tiliacez like the other members of that class are mucilaginous and emollient in their pro- 
perties, and as such, are employed in medicine, in almost every country in which they are found, 
a few, such as Corchorusolitorius are used as pot herbs. But it is in the arts they are most 
extensively applied. The fibres of the bark of nearly all, are esteemed on account of their 
strength, and in this country are spun into cordage, or made into cloth. The fabric known 
in England under the name of Russian mat or bass, is made from the inner bark of the Lime 
tree, Tilia europaea. The wood of several kinds is also valuable: the excellent Trinco- 
malee wood of Ceylon, is the produce of Berria Ammonilia, The Grewia elastica, of Royle, 
affords timber much valued for its strength and elasticity, and is therefore used for making 
— and bandy shafts. A Brazilian species Lechea paniculata affords a bark used in tanning 
eather. 
Remarks on Genera &c. The number of genera enumerated as belonging to this order 
The Indian species of these genera are with the exception of Grewia, generally of easy 
discrimination, but some of those of Grewia, if really distinct (which I somewhat doubt) are 
most difficult to distinguish with other than most perfect specimens, the fruit affording the best, 
if not indeed the only marks by which they can, with certainty, be determined. G. orientalis 
‘and G'. columnaris, are so much alike, that I find it almost impossible to say to which I ought 
toyrefer many specimens, not in fruit, which have recently been added to my collection. Our 
G. emarginata is very nearly allied to both, but readily distinguished by its globosely lobed 
fruit. G. hirsuta and G. pilosa are also so closely allied that it becomes difficult to decide to 
which, some of the extreme forms of each belong, and leads to the inference that they are but 
varieties, unless the cleft petals of the latter be found sufficiently constant to keep them distinct 
Grewia villosa of India is certainly identical with @. corylifolia of the Flora Senegambie, but I 
cannot perceive that any of the others are, unless perhaps G. bicolor, which from description, 
appears very nearly related to G. Rothii, except in the fruit which is stated to be globose in the 
one, and 2-jobed or dydimous in the other, apparently aan excellent distinction, As this is a 
very difficult family, I propose shortly publishing figures in my Icones, of a number of them.
