If the foregoing supposition be correct, those species of Azolla alone, that have 

 radicles either plumose throughout, or to a greater or less distance from the apex, 

 will present this calyptra. M. Meyen does not notice any such calyptra in 

 bis account, and I do not understand what Martius means by a calyptriform 

 spongiole — still less by the phrase " spongiola conica vestita," op. cit, p. 124. 

 Figs. 2, 3. of his work, would appear to represent a calyptra of some sort.
