while the later developed ones are trifoliolate, but with the 

 leaflets of the same shape as the first one. That the primary 

 root is long persistent is to be seen in Fig. 44, which rep- 

 resents the rhizome of a flowering plant. The tubercles are 

 also especially to be observed here on the lateral branches 

 of the root and we see further the short, ascending rhizome, 

 merely consisting of the lowest part of the stem, from the 

 base of which buds are developed, forming the prostrate,

decumbent branches. 



Lespedeza procwnbots. J^ 



In regard to germination this species differs a little from 

 the above-mentioned one in having the first leaves, next the 

 cotyledons, opposite. They are unifoliolate, with the leaflets 

 broadly cordate and pointed, while these in the final leaves ! 



are obcordate, with the apex retuse (Plate IX, Figs. 45,46). The \ 



first two or three leaves next to these show the same shape, I

but are alternate. The whole germinating plantlet otherwise 

 much resembles that* of L. violacea^ as regards the shape of the 

 cotyledons, the development of the hypocotyl and the 

 primary root. The rhizome of the full-grown plant (Fig. 

 46) agrees entirely with that of L, violacea. 



Clitoria Mariana. 



There are a few points of interest which may be men- 

 tioned in the germination of this plant. The hypocotyl is 

 rather long, straight and pubescent, while the cotyledons, 

 which are sessile, ovate and obtuse, are perfectly smooth. 

 The first two leaves, next above the cotyledons, are opposite, 

 ovate and acuminate, and the primary root is slender, with 

 several thin branches, but destitute of any tubercles. 

 There is quite a considerable difference between a Gfcrminat- \ 



ing plantlet of this species (Plate IX, Fig. 47) and of that of 

 C. teruatea, which has been figured by Lubbock.^ In this ^ 



species, the cotyledons are more obtuse, and the first leaf 

 after them is already trifoliolate. 



As to the full-g*rown plant of C. Mariana, the leaves are
