on account of the difference of ‘structure which its ovary presents. In X, flavescens, Roxburgh 
describes and figures the ovary as having two tubercles rising from the base, each bearing two 
erect ovules, and in his X. virens, he represents the placente as forming two projections, 
one from each side of the ovary extending its whole length, and each bearing from 4 to 6 ovules. 
In my plant, I find only 4 ovules, as in /lavescens, but differently situated, one namely from 
each extremity of each placenta, one ascending the other pendulous. On this account it ap- 
proaches more nearly to X. virens, but in that species each placenta bears from 4 to 6 ovules in 
two rows. I may here observe that in our Prodromus we have fallen into an error in adopting 
but it differs in the structure of the ovary, the principal point of difference between Roxburgh’s 
two species. From X. virens, both the present species and flavescens of the Prodromus differ 
in the absence of a glandular enlargement of the veins on the lower surface of the leaves, and 
in changing to yellow in drying. The very distant stations of the two plants, tend, still further, 
to confirm the opinion that they are distinct. On this point however, I refrain from offering 
any decided opinion, as I have not seen a specimen of the original X. virens. Among m 
specimens from Courtallum and Ceylon, there are five distinct forms, which may be thus dis- 
tinguished and named—Ist, the one here figured, X. angustifolium. 2d, one with subsecund. 
spicate racemes, elliptic, shortly acuminated, green, leaves; ovary with four ovules, 2 erect and 
2 pendulous, X. Roxburgianum. 3d, one with hard coriacious reticulated, glabrous, acuminated 
4th, the form described in our Prodromus under the name of X. flavescens, but which 
I now consider quite distinct from Roxburgh’s plant, X. 4rnottianum: and lastly, one from 
Ceylon, with oval leaves, ending in an abrupt, rather long pointed, acumen; the ovary 4-ovuled, 
the ovules attached to the base, ascending ; probably the true X. flavescens of Roxb: the figure 
of which it greatly resembles.
