" 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
