CHARACE^. 



cato, nucleo conform intersulco ultra nuclea in stigma? 5 lob. 

 (lob rectis) producta. Fructus vel nudi vel ramulis persis- 

 tentioribus, stipate oblique directione (ovala) ovati ; stigmato 

 fere immulato terminate corpora nucleari fibra spirale notat. 



Tegument exter, separabili, membrana spiras leviter notata, 

 interna duro, atro, ob spiras projicientes quasi echinato (along 

 the sides,) materies farinaceo, en viscosa mixta granulis amylo- 

 sis quam maxima inaequalibus. The young rami, as well as all 

 the ramuli have no outer cells, hence Nitella is chara in an 

 earlier state. 



It is obvious that the so called stigmata are not so, for they 

 present no change at any period. 



In Musci, — the lowest pistilliform plants, the stigma un- 

 dergoes manifest changes. 



Nor has the male any relation to the males of the lower 

 orders.

The joints consist of an outer hyaline rather tought coat, 

 and a central green lining membrane 



The ultimate joints are acute, and may be seen terminating 

 the ramella.

 lar roundish or angular globuline, held together by nothing 

 appreciable even to 500 magnif.
