812 Remarks on a collection of Plants, $c. [Dec. 



order I am not acquainted, and to that of Butomese ; and hence the 

 anomalous situation of the seeds. At the period of expansion of the 

 flower, the ovula are much less developed than is almost universally 

 the case : they present indeed the appearance of ovula at the earliest 

 stages of development. I refer to this order a plant with long ra- 

 cemes of ternarily aggregate fruits, notwithstanding that it has milky 

 juice, and that the Cotyledons are large, foliaceous and obliquely 

 situated with regard to eaeh other. 



Among the Cyrthandraceee a species occurs, (Chiliandra obovata, 

 mihi,) remarkable for the structure of its mature anthers. These de- 

 hisce in a labiate and incompletely bivalvular manner, the lower and 

 smaller valve being alone half reflexed. This valve is compound, 

 and due to the mutual adhesion of the originally distinct inner locel- 

 lus of each loculus. To this formation 1 have adverted in a short 

 memoir on Rhizophoreae, published in the Transactions of the Me- 

 dical and Physical Society of Calcutta, although I was at the time 

 ignorant of the existence of an example. Assam contains another 

 interesting species of this family : this, which is remarkable for its 

 pentangular petaloid calyx, and the " dehiscentia circumcisa," of its 

 fruit, in which it approaches to Aikinia of Mr. Brown, I propose 

 calling Cyananthus. 



Scrophuhrianece afford one new genus, (Synphyllium torenioides, 

 mihi,) an account of which will appear in the Journal of the Madras 

 Literary Society, edited by my friend Mr. Cole. 



Asclepiadece contain some interesting species, of which one consti- 

 tutes probably a new genus, unless, indeed, it is referrible to Dr. 

 Wight's Heterostemma, from which it would appear to differ in the 

 valvular aestivation of the corolla. This species is remarkable for the 

 aliform processes running along the larger veins of the under surface 

 of the leaves. 



To this order, or to Apocynea?, is to be referred a remarkable plant, 

 distinguished by the numerous longitudinal foliaceous alae of its 

 follicles, and, I speak from memory, its serrated leaves. This plant, 

 which I have seen near Mergui on the Tenasserim coast, seems to 

 have been sent by Captain Jenkins to Dr. Wallich with many 

 others, none of which appear, however, to have excited much at- 

 tention. 



Among the Boraginece we find one Myosotis and a species which, 

 with the habit of some Anchusee, appears to be not referrible to any 

 genus of the order. The " umbilicus" occupies the centre of each 

 carpellum, and is surrounded by an osseous elevated margin. The 

 origin of this is totally distinct from that of Myosotis, and is wholly 

 independent of fecundation. The radicle is in addition inferior.
