130 ILLUSTRATIONS OF INDIAN BOTANY. 



baminous seed and capsule dehiscing laterally, not vertically, is a very anomalous order, having, 

 apparently, no really near relations. As regards placentation it undoubtedly associates with, 

 and was at first referred to, my first group (where it is placed in plate 142), but the ovary 

 hai only two carpels and the flowers are irregular. Owing to its "having the same calyx, 

 corolla, stamens and bivalve capsules,'" as Scrofulariaceae, many eminent Botanists esteem it 

 more nearly allied to that order than to any other, and, in deflerence to their judgment, I was 

 at first disposed to place it in my last group, though I thought the relationship remote. I 

 now prefer placing it here because I feel disposed to view it as much more nearly related to 

 Cyrtandraceoe than to Scrofulariacece, and consider that this is its proper location in the 

 Vegetable system. The habit, the lateral not vertical dehiscence of the capsule, and the exal- 

 bnmlnous seed, all combining to confirm this view and show that its affinities appertain 

 much more to Cyrtandracece than Scrofulariaceae. Orobanchacece, which I have brought 

 here on account of the ovarial structure, is one of those complex families which claim relation- 

 ship with several others, but is, I believe, notwithstanding its albuminous seed to the full as 

 naturally stationed here as in either the Gentianal Alliance, where Lindley places it, or in the 

 Solanal to which it is usually referred. It seems in fact to form the connecting link between 

 the Bignonal and Solanal groups, fluctuating between CyrtandracecB and ScrofulariacecR, having 

 the ovarial structure of the former, the albuminous seed of the latter, and the flowers of both. 

 Acanthacese certainly belongs to this group. 



The sixth group forms a very natural assemblage, ErycibecB, perhaps, excepted, the true 

 aflinities of which are still undetermined. Lindley refers the genus Erycibe to Ebenacea;, but 

 I think erroneously. I have brought it here on account of its basal placentation, besides which 

 it has at different times been referred to both Convolvulacece and B or raginece and is finally 

 raised to the rank of an order by De Candolle and placed between them. 



The orders of the seventh group seem all nearly related. HydrohacecB forms the con- 



of SolanacecB.
