74 BRITISH CHAROPHYTA. 



fossulae (fossuldj a little ditch), the spaces between the ridges 



of the oospore, termed also sulci. 

 globule,, a term applied to the antheridium. 

 glceocarpous (yXoios, mucus ; nap-roc, fruit), having the repro- 

 ductive organs enveloped in mucus, 

 gymnocarpous (yvfivoc,, naked ; KCI^TTOC, fruit), not having the 



reproductive organs enveloped in mucus, 

 gymnophyllous (yv[n>o, naked ; $v\\ov, a leaf), having 



branchlets destitute of cortex, 

 gymnopodous (yv/nvoc, naked ; TTOVZ, a foot), having the lowest 



internode of the branchlet ecorticate. 

 tgyrogonites (yupoe, round ; yo vi), a seed), the name applied 



by earlier geologists to the fossil fruits of Charo- 



phytes. 

 fgyroliths (yvpocj, round ; \iOoc., a stone), another name for 



the fossil fruits, 

 haplostephanous (awXb^, single; are^avoc, a crown), having a 



single circle of stipulodes at the base of each whorl of 



branchlets. Haplosfephanx, a section of Chara. 

 haplostichous (a-n-Xbg, single; ariZ, a row), having a cortex 



with one row of cells to each branchlet or bract-cell. 



Haplostichae, a subsection of Chara. 

 head-cells, (1) cells attached to the distal extremity of the 



manubrium, and bearing the filaments which contain 



the antherozoids; (2) cells produced on the exterior of the 



node-cells of the stem-cortex in some species of Chara, 



and bearing the spine-cells, 

 heterophyllous (trtpoc, different ; (f>v\\ov } a leaf), having 



branchlets of more than one form. Heterophyllse, a 



subsection of Nitella [Brauu] . 



holodactylous (oAoc, whole ; SaKrvXoc, a finger), having ulti- 

 mate rays or dactyls, each composed of a single cell. 



Holodactylte, a section of Nitella [Hy]. 

 hoinoeophyllus (oftoioc, like; fyvXXov, a leaf), having but one 



form of branchlet. Homceophyllse, a subsection of Nitella 



[ Braun] . 

 isostichous (//CTOC, equal ; art, a row), having equal rows, 



applied to the stem-cortex of Chara } when the primary 



and secondary rows are of equal diameter, 

 lamellae (lamella, a thin plate), the layers of the membrane of 



the oospore. 

 lime-shell, a hard shell surrounding the oospore, formed by 



a secretion of lime within the spiral-cells of the 



oogonmm.
