SPECIFIC DISTINCTIONS. 



In Lichen 7 , the fructification is distinguishable into Tubercu- 

 lum, a little knob, which is a fructification, consisting of rough 

 points collected like a heap of dust Scutellum, a s?nall buck- 

 ler, which is a concave orbiculate fructification, the margin of 

 which is elevated on every side ;...or Pelt a, a little shield, which 

 is a plane fructification fastened for the most part to the margin 

 of the leaf*. 



In Mosses, the Capitulum, or little head, is an Anthera. 



In Grasses, Spicula, a little spike, is a partial one ; the Aris- 

 ta is tortili, misted, when it has a twisted joint in the middle. 

 Articulus, a joint, is the part of the culmus that lies between 

 two geniculi, or knots. 



A radiate compound flower consists of disk and radius. The 

 radius is composed of irregular corollulse in the circumference J 

 and the disk of smaller corulluhe, that are for the most part re- 

 gular. 



A decompound flower contains within the same calyx lesser 

 calyces, that are each of them common to many flowers, as in 



Sp:^ tRANTHUS. 



Th- Corolla is said to be equal, when its parts are eqtial in 

 figure, magnitude, and proportion unequal, when the part's 

 answer in proportion, though not in magnitude, so that the 

 flower conies out to be regular ^...regular, when it is equal in re- 

 spect to the figure, magnitude, and proportion of the parts ^..ir- 

 regular, when the parts of the limb differ in figure, magnitude, 

 or proportion. Eictus, a gaping, or grinning, is the gap or 

 opening between the two lips of the corolla. Faux, the gorge, 

 or gullet, is the opening of the tube of the corolla. Palatum, the 

 palate, is a gibbosity, or bunching out in the faux of the corolla. 

 Calcar, a spur, is a nectariurn extending in a cone in the hinder 

 part of the corolla. The corolla is Urceolate, pitcher-shaped, 



* The terms explained here, and in the following paragraphs, respect such cir- 

 cumstances of the parts of fructification as concern rather the specific differences 

 ? han the classic,, or generic ones; and we have therefore followed Lmnteiis in sub* 

 joining them to this head, notwithstanding that some few of them have been already 

 mentioned and explained in the First Tort of this wo>& Author.
