FIGS. 12-17. Microscopic sexual reproductive features of Gibsmithia hawaiiensis. The specialized cells, 
a-d, are similar in nature whether in a carpogonial or auxiliary-cell branch. On the latter, the piliform exten- 
sion, h, shows as a multicellular hair, the cells of which are in staining reaction and appearance, rather like 
vegetative cells of similar size and relative terminal position elsewhere. 12-14 , Carpogonial branches with or 
without nonfertilized carpogonia, cp. The hypogynous cells a-d were always densely granular and their contents 
took up aniline-blue from aqueous solution much more than did the other nearby cells. Cell b was usually 
smaller and the contents were usually different from the rest. Cell c was almost always the largest. The num- 
bered cells, 1, 2, 3, etc., represent cells that looked like the strictly vegetative cells of similar size and position 
nearby and connected the carpogonial branch to a medullary cell, med. The cytologically similar cells of the 
sterile branchlets are indicated as la, lb, lc, etc. (Collection No. 10386.) 15, A nonfertilized auxiliary-cell 
branch arising from one of two opposite branch systems of the same medullary cell, med, the one vegetative 
branch system, veg, being of only three cells, the other more extensive and bearing an auxiliary-cell branch.
