FUN ARIA HYGROMETRICA 135 



between the leaves and the stem. It is a peculiarity of 

 the Mosses that lateral buds always rise from the stem 

 at a point immediately below the leaves with which they 

 are associated. The growth of all Mosses is apical, and 

 is due to the divisions of a particular cell in the apex of 

 the stem, or of the leaf, as may be. 



In Funaria, the organs of sex, the antheridia and 

 archegonia, occur on the same plant, which is on this 

 account termed " monoecious (Gr. monos, single ; oikos, 

 a house). In Plate IV., Fig. 11, is shown the tip of a 

 male shoot, a marks the antheridia, which in Nature 

 are about y 1 ^ inch in length when mature; b indicates 

 the paraphyses (see p. Ill), which probably serve to 

 hold water and secrete it when it is required by the 

 antheridia. These latter are delicate organs entrusted 

 with a vital mission, so they must be protected and 

 served in accordance with their peculiar needs. In the 

 same figure, at d, we have a drawing of a single sperma- 

 tozoid, one of many liberated by the antheridia. It 

 should be noted that the male shoots of Funaria attain 

 a height of about f inch, and that the leaves at its top 

 form a crowded rosette, which appears reddish in the 

 centre. 



The female shoots rise as side-branches from the male 

 stems; they are relatively small, and may number one 

 or more per stem. The leaves at the tips of these shoots 

 are arranged in a budlike manner, and enclose the 

 archegonia. The fully grown archegonium is very like 

 that found in Liverworts; in Plate IV., Fig. 15, we see 

 a representation of one enlarged considerably Jc is the 

 neck along which a canal runs into the venter, I, and m 

 is the egg-cell. When the archegonium is ripe for
