122 STUDIES OF NATURE. 



vvh.it I have juffc been advancing. For example, 

 the fcorzonera Gi'aca faxatilis à? maritima foliis varié 

 laciniatis, (the Greek fnxatile and marine fcorzo- 

 nera, with leaves varioufly fcoUoped) which is 

 there reprefented, has it's petals, or half-flowers, 

 fquared at the extremity, and plane in their fur- 

 face. The flower of the ftachis Cretica lafifolia, 

 (the broad-leaved ftachis of Crete) which is a mo- 

 nopetalous tubular plant, has the upper part of it's 

 corolla undulated, as well as it's tube. The cam,- 

 ■panula Grata faxatilis jacobeœ foliis , (the Greek bell- 

 flower of the rocks, with ragwort leaves) prefents 

 thefe confonances in a manner ftill more (biking. 

 This campanula, which Tour nef or t confidcrs as the 

 moft beautiful he had ever feen, and which he 

 fowed in the Royal Garden at Paris, where it ftio 

 | ceeded very well, is of the pentagonal form. Each 

 of it's faces is formed of two portions of a circle» 

 the focufes of which, undoubtedly, meet on the 

 fame anthera ; and the border of this campanula 

 is notched into five parts, each of which is like- 

 wife cut into the form of a Gothic arch, as each 

 fubdivifion of the flower is. Thus, in order to 

 know, at once, the curve of a flower, it is fufficient 

 to examine the brim of it's petal. 



It is of much utility to attend to this obferva- 

 tion, for otherwife it would be extremely difficult 

 to determine the focufes of the petals. Befides,
