    XI A RSI LEACE.E. r»74 The spores are highly developed, analogous to those of some Khasya Ilepaticae. They appear to have 3 spores, and close- ly resemble pollen. It is remarkable that in some, in their earlier stages before the division of the parent cell, I have ob- served emission of the contents of the young spore, but not of the parent spores. The glandular cordate mass is the male, notwit hstandimr its permanence, and the quick withering of the suffulting part of the leaf. I want observations on its stages, and on its origin. It will be curious if the lamina sufTulting it, which is not lunate, be an indusium. One thing is certain, that in this species the contents of the female are one and the same, notwithstanding the temporary difference which only affects the size and sphericity and con- tents, the internal organization of the coats being the same. The stride are the result (?) of the ternary or quaternary approximation. Lastly the leaves have stomata on their inner flat face. En- dlicher says they have none but let him consult l)e Candolles plate, etc. in the Organographie, as regards I. lacustris.] rlhe cells contain a few globular bodies of considerable size consisting of a spherical hyaline sac containing 3 young spores nearly perfectly formed, the spiculae of the angles being visible. It is remarkable that immersion in water causes the more or less partial emission of the granular nucleus from the pores so that the number cxceds 3, and is often upwards of 6. In this extensible nucleus, a nucellar is generally observable, this is seen sometimes in the protruded part ; sometimes in the spore; mostly the lax cells of the surface of the septa have disappeared but the lining is still fuscous ; under 1-500 the mass looks commencing to be cellular, it has also plenty of granu- les, iodine does not act on the cell, but colours fuscous both spore and extensible stuff.J [The protrusion of the contents of the sporilorm nuclei appears constant.
