and along the convexity, being stretched as it were from 

 point to the other. Cavity containing globose cellular 

 one looking bodies which, judging from pressure escape, 

 as they are mucilaginous or oily. 



Note. — The following is copied from pencil writing on the margin of 

 the sketches of Psilotum triquetrum, PI. CXVIII,A. and as it continues 

 the analyses from fig. XII. to the end, as noted down by the author at 

 the time of observation, it is given entire. Ed.

I. In this stage which is the earliest, the female is a brownish mem- 

 branous bag, containing grume and rudimentary cells or oval bodies 1, 2, 

 the edges hyaline entire. The young suffulting body consists of two 

 primary points, so it cannot therefore be a simple organ. 



II. No opaque lines are seen in the marginal cells, which when they 

 are viewed as an opaque object, appear hyaline and membranous. 



Although the 3 valves are marked out externally, the whole appears 

 a mere cellular body, containing grume, and ovate, or oblong interspersed 

 ru'liments of cells. 



III. Suffulting bodies now convex internally. Deep bilobed calyx 

 cellular. Cells prominent, in the centre of the inner face is the globular 

 young fruit. (1.) 



The young fruit appears to be cellular outside, or it presents markings 

 of cells. 



The male is composed of cells each crowded with molecular matter. 



The female contains grume or grannules, after this has escaped 1 have 

 not seen cells in it. This last is invariably the precursor of the formation 

 of cellular tissue. A mucillaginous fluid in which minute often move- 

 able granules are, as it were suspended, (a, female inner view, b, back.) 



IV. At this stage the capsule is evidently trilocular, the walls thick 

 cellular, opaque by granules, the cells are filled each with a detachable 

 grumous cellular mass, the outer portions of which are, I think, most se- 

 parable. The mass about this time is composed of a number of large 

 cells, in each of which are many nuclei. 



Pressure shews large cells in the centre, with indistinct parietes, and 

 several nuclei ; but towards the circumference the nucleus is detached, no 

 membrane is visible, or agregation. There is little if any difference 

 in size between the nuclei and the distinct granules. All are immersed 

 in grume, the very outermost do not seem to separate within the mass, but 

 will be found in the cavities of the cells.
