236 INDEX. 



PAGB 



VII. THE FELUM. The running stem of a creeping plant. 



It is not specified in the text for use ; but will be necessary ; 

 so also, perhaps, the Stelechos, or stalk proper (26, p. 104) the 

 branched stem of an annual plant, not a grass ; one cannot 

 well talk of the Virga of hemlock. The ' Stolon ' is explained 

 in its classical sense at page 100. but I believe botanists use 

 it otherwise. I shall have occasion to refer to, and complete 

 its explanation, in speaking of bulbous plants. 



VIII. THE CAUDEX. The essentially ligneous and compact part of 



a stem 105 



This equivocal word is not specified for use in the text, but 

 I mean to keep it for the accumulated stems of inlaid plants,

IX. THE AVENA. Not specified in the text at all ; but it will be 

 prettier than ' baculus,' which is that I had proposed, for 

 the ' staff' of grasses. See page 113. 



These ten names are all that the student need remember ;

STIPS. The origin of stipend, stupid, and stump 104 



STIPULA. The subtlest Latin term for straw 104 



CAULIS (Kale). The peculiar stem of branched eatable vegetables 105 



CANNA. Not noticed in the text ; but likely to be sometimes use-

III. THE LEAF. 



Derivation of word 22 



The Latin form ' folium ' 32 



The Greek form 'petalos' 33 



Veins and ribs of leaves, to be usually summed under the term ' rib ' 34 



Chemistry of leaves 30 



The nomenclature of the leaf consists, in botanical books, 

 of little more than barbarous, and, for the general reader, to- 

 tally useless attempts to describe their forms in Latin. But
