OF THE PEINCIPAL TECHNICAL TEEMS USED 

 SPARINGLY IN THIS WOEK 



Like every other profession, Gardening has its own peculiar terms and expressions, which 

 are readily understood by the skilled practitioner. To the amateur, however, such technical 

 terms and expressions are often bewildering when not explained in simple language or with- 

 out illustration. To meet this difficulty, and to encourage the amateur to take a keener 

 interest in the plants he may have in his garden, the technical terms used in this work are 

 explained in the following glossary. In all cases where there is likely to be some doubt as 

 to the meaning, an illustration has been given. It must, however, be understood that as 

 regards form, it may often be necessary to use two or more terms to convey an accurate idea. 

 Thus a. leaf may be called ' ovate-lance-shaped ' which means that its shape is somewhat 

 between ovate and lance-shaped— it is broader than lanceolate (fig. 68) and narrower than 

 ovate (fig. 75). And so on with other expressions. As a rule the mere botanical expressions 

 have been avoided as far as possible in the body of the work, wherever a suitable English 

 one could be substituted without inaccuracy. ' 



Abortive, Abortion, imperfectly formed or 



rudimentary, as is often the case of stamens 



and petals. 

 Acanthus, spiny. 

 Acaulescent, Acaulis, apparently stemless, 



as in Primroses and other plants where 



the spaces between the joints are very 



short. 

 Accrescent, growing after flowering is over, 



as with the calyx of Physalis Francheti 



(p. 691). 

 Accumbent, lying against a thing, applied 



to the seed leaves or 



cotyledons in the seed. 

 Acerosus, needle-shaped, 



as the leaves of Pines, 



&c. (see Acicular). 

 Achene, Achenium, a 



hard dry one-seeded 



superior fruit, as in 



Buttercup, Clematis, 



Strawberry. In fig. 1 



the left hand drawing 



shows a magnified achene of a Buttercup 



with a section of the ovary, within which

the seed s appears. The stigma is shown 

 at St. The right-hand drawing shows a 

 feathery achene of Clematis. The fruit Is 

 at /, and the awn at a. 



Achlamydeous, flowers 

 without sepals or 

 petals, as with most 

 of the plants de- 

 scribed from p. 759 to 

 p. 805. 



Acicular, needle-shaped, 

 as in the case of Pine 

 leaves (fig. 2). 



Acinaciform, scimitar- 

 shaped, like leaves of some Mesembryan- 

 themums. 



Acrogenous, growing from the apex, as in 

 the case of Ferns. 



Aculeate, armed with prickles, as the 

 stems of Eoses, Brambles &c. (fig. 3).

 right angle at the tip.
