THE GLANDS. 91 



vasculaires) present, as the preceding, a cellular tissue 

 of a coarse texture, but traversed in different directions 

 by vessels. They do not exude a particular fluid : this 

 causes us to think that they are recrementitial, that is 

 to say, that they are destined to prepare a particular 

 fluid, which is again absorbed, and employed in the 

 interior of the body of the plant ; such is, for example, 

 the thick and whitish appendage which is found at the 

 bottom of the flower of Cohcea. 



This division into Cellular Excretory and Vascular 

 Secretory Glands, deserves to be studied in a greater 

 number of plants than it has hitherto been. But inde- 

 pendently of glands visible to the eye, there certainly 

 exist in plants a great number of points or glandular 

 surfaces, which secrete certain fluids, which have as }'et 

 escaped our anatomical researches. 



To complete the narrative of our actual knowledge 

 with regard to glands, it is necessary for us to examine 

 the Hairs, and Reservoirs of Proper Juices ; this will 

 form the subject of the following chapters.
