THE GLANDS. 89 



{glandiilcB miliar es ; glandes miliaires) to the Stomata, 

 which we have described in one of the preceding chapters. 



Under the name of Globular Glands {glandiilce 

 globulares ; glandes glohulaires) some have described 

 certain spherical bodies, which cover the inferior surface 

 of the leaves of some of the Chenopodiacese — as the wild 

 Orach — and which are secreted matters analogous to 

 glaucous powder ; others have applied this name to the 

 little spherical globules which are observed upon the 

 leaves of the Labiatas, the nature of which is not well 

 known. 



Vesicular Glands {glandulce vesiculares ; glandes 

 vhiculaires) are vesicles full of essential oil, situated in 

 the leaves of the Myrtle, the rind of the Orange, &c. 

 We do not know if these are true glands, or simple 

 reservoirs of a fluid secreted by some neighbouring 

 organ. We shall revert to this subject when we speak 

 of the Receptacles of Proper Juices. 



Utricular Glands {glandulcB utriculares ; glandes 

 utriculaires) are projecting vesicles full of limpid alka- 

 line fluid, formed upon the convexity of the external 

 cellules ; as, for example, in the Ice-plant, {Mesemhry- 

 anthemum crystallinum.) We shall return to this 

 article when speaking of Hairs. 



Lenticular Glands {glandulcB lenticulares ; glandes 

 lenticul aires) are little spots which are found upon the 

 branches of trees, and which indicate the points from 

 whence adventitious roots may be developed under 

 favourable circumstances. We have described thera 

 above under the name of Lenticels. 



All these organs, and others resembling them, most 

 improperly deserve the name of Glands, which we intend 

 to reserve for the following : — 



1st. Urceolate Glands {glandules urceolares ; glandes 

 a Godef) are little fleshy, often concave, tubercles,
