LAHORE TO SIMLA. 



ted ridge, the ends of which do not meet, but one of which originates 

 from an elevation to which the depression would seem to respond. 

 The straight line does not correspond with the funicle, which is not 

 straight, but is pushed up in a curved form against the upper edge 

 of the cell. 



It corresponds, however, with a straight subclavated line running 

 from the hilum to the elevation whence the curved line originates, 

 although this correspondence is not always well marked. 



a. funicle. 



b. cell. 



c. line and depression. 



d. seed. 



e. line on seed, ending in a boss 



from which an elevated curved 

 line originates. 



The above marking, corresponding as it does in the flat part of the 

 legume with the funicle, evidently points to a peculiarity in the dis- 

 tribution of the vascular system ; probably it consists of the testa, and 

 if so, it is worthy of remark, as the main vessels ordinarily a single 

 one, run along the edge, and not on the flat surface of the fruit. 



I know of no similar instance ; in this plant the vessels of the testa 

 are distributed primarily at right angles with the placenta, and not 

 in parallel lines with that organ. If the seed were depressed instead 

 of compressed, it would not present this peculiarity, although even 

 then the two primary vessels would be remarkable. From this 

 instance it may be assumed that the hilum may only be denned cor- 

 rectly as the spot of union between the body of the seed and the 

 funiculus. The leaflets of the plumula are pinnate. 



It is also curious that the distribution of green parenchyma is along 

 the course of the veins of the legume, and that there is a more 

 minute reticulation, and a greater development of the green colour on 

 the faces of the cells, than on any other part of the surface of the
