" It is possible that the plant here figured/' Mr. Brown 

 observes, " may belong to a species different from 8. adna- 

 tum, whose spike is generally sessile, and more subdi- 

 vided ; I am inclined, however, to unite them, and to add, 

 as a third variety, 8. propinquum, which was taken up from 

 imperfect materials. In the section of the genus to which 

 8. adnatum belongs, the best specific differences are found 

 in modifications of the structure of the capsule, and by 

 these alone the species at present known may be readily 

 determined. Thus, in 8. breviscapum the cells and valves 

 of the capsule are in form and contents perfectly equal, as 

 in the other sections of the genus. In fasciculatum the 

 cells are dissimilar in form, but of nearly equal size, and 

 both fertile. In falcatum the posterior cell, still more 

 different in form, is also considerably reduced in width 

 and entirely without ovula ; nor is it, as I have stated in 

 the specific character, fertile. Lastly, in adnatum, of wdiich 

 I am now disposed to consider propinquum a variety, the 

 posterior cell is not only entirely destitute of ovula, but is 

 reduced to a capillary tube, which continues to adhere to 

 the fertile cell. From this series of species, in which the 

 upper or posterior cell is gradually obliterated, we are led
