branchlets, the wliorled processes of limited growth, produced 

 at the stem-nodes, and bearing the reproductive organs ; 

 by some authors styled "leaves." 



bulbils (bulbulus, a little bulb), agglomerations of cells 

 containing starch granules developed at the root- and 

 stem-nodes of some Charophytes. 



capitula {lat. little heads), the head-cells in the antheridium. 



charads, a name for the group of Charophytes. 



tclonarium (kAoiv, a young branch), a term applied to the 

 oogonium. 



tcondylium {kovSvXo^, a knuckle), a term applied to the 

 antheridium. 



conoid {kuivoq, a cone; uSoq, resemblance), cone-shaped. 

 Conoidem, a section of Tolypella having conical ultimate 

 cells to the rays of the branchlets. 



coronula (lat. a little crown), the small crown-like process of 

 five or ten cells surmounting the spiral-cells of the 

 oogonium, sometimes styled corona or crown. 



cortex [laf. bark, rind), the celluhir sheath surrounding the 

 stem and branchlets of some Chareie ; cortical-cells, the 

 cells of which it is composed, distinguished as primary 

 and secondary; the primary representing the axis of each 

 cortical series, and consisting of nodal and internodal 

 cells ; the secondary consisting of the lateral cells given off 

 by the nodal cells, and lying alongside the primary series. 



cyclosis (kukAoc, a circle), the rotation of protoplasm within 

 the cell. 



dactyl (SoKTuXoc, finger), an ultimate ray of the branchlet of a 

 Nibella. 



diarthrodactylous (Stf, twice; a^Qpov, a joint; SoktuXoc, a 

 finger), having each dactyl composed of two cells. 

 Diarthrodactylx, a section of Nitella [Braun]. 



diplostephanous (S(;rAooe, double ; GTi<p<xvor, a crown), having 

 a double circle of stipulodes at tliG base of each whorl of 

 branchlets. Diflostephanm, a section of Ghara. 



diplostichous (SittXooc, double; arl^, a row), having a cortex 

 in which there are two rows of cells to each branchlet or 

 bract-cell. Diplostichss, a subsection of Ghara. 



tepigone (tTrl, upon ; yovi], offspring), a term applied to the 

 oogonium. 



flabellate (flabellum, a fan), having the secondary rays of the 

 branchlet once or repeatedly furcate. Flahellatse, a 

 subsection of Nitella. 



flask-cell, the stalk-cell of the antheridium.
