his inspection, who wrote me in reply that he could see the di- 
vision into four pretty distinctly. 
I have since observed the same peculiarity in the spores of 
Tyndaridea insignis, Hass., and Staurocarpus gracilis, Hass., and, 
as Mr. Berkeley remarks to me, it may prove more general than 
has hitherto been supposed. ‘The separation of the contents of 
the sporangium into four portions does not take place in our three 
species until the fruit is nearly mature, and this soon afterwards 
becomes too opake for the character to be seen, so that it can be 
observed only in a particular state of the plant. The sporangium 
in all the species I have mentioned is more or less compressed 
vertically. 
Mesocarpus scalaris may occasionally be observed with some of 
its cells considerably inflated ; and each of these enlarged cells is 
found to contain a globose echinulate body very much resembling 
the sporangium of some of the Desmidiee, and respecting the 
character of which it is difficult to determine: this body may first 
be seen as a very small spherical cell, apparently quite smooth, 
and containing an oily-looking fiuid ; it subsequently grows much 
larger and becomes furnished with several long curved spines: 
its texture seems to be corneous. It does not appear to be de- 
veloped at the expense of the endochrome of the cell which con- 
tains it, but in some instances I have thought the quantity of 
endochrome rather larger than usual in the inflated cells. Can 
this curious body be an abnormal growth of the nucleus, or is it 
an internal parasite? Some of the cells of a Tyndaridea received 
from Mr. Ralfs, have within them a fusiform transversely ribbed 
body, which is probably of a similar character to the spherical 
ones found in the Mesocarpus.

Brrorz my departure from Malaga I visited, in the beginning of last 
month, the southern portion of the Sierra de Mijas, lying near the 
village of Chuniana. Along the bank of the Guadalhorce oceurred 
Scolymus maculatus, L., Achillea Ageratum, L., and various Carices in 
flower, and on boulders and sand above Chuniana and on the slopes 
of the mountain-chain blossomed Ruta montana, L., a small form of
