396 MEIOPHYLLT OF THE 



Partial suppression of the leaf occurs sometimes in 

 compound leaves, some or other of the leaflets of which 

 are occasionally suppressed. Sometimes, as Moquin 

 remarks, it is the terminal leaflet which is wanting, 

 when the appearance is that of Cliffortiat at other 

 times the lateral leaflets are deficient, as in Citrus or 

 Phyllarthron. Ononis monophylla and Fragaria inono- 

 phylla may be cited as instances of the suppression of 

 the lateral leaflets. If the blade of the leaf disappears 

 entirely, we have then an analogous condition to that 

 of the phyllodineous acacias. 



With reference to the strawberry just mentioned, 

 Duchesne, * Hist. Nat. Frais.,' p. 133, says that this 

 was a seedling raised from the fraisier des hois, and 

 the characters of which were reproduced by seed, and 

 have now become fixed. The monophyllous condition 

 has been considered to be the result of fusion of two 

 or more leaflets, but however true this may be in some 

 cases, it is not the case with this strawberry. M. 

 Paillot states that he has found the variety in a wild 

 state. ^ 



In like manner varieties of the following plants 

 occur with simple leaves, Bosa herbenfoliu (Lmvea), 

 Buhus Idceus, Bobinia pseudacacia, Fraxinus excelsioVy 

 Samhiicus nigra, Juglans nigra, &c. 



In one instance seen by the writer every portion of 

 the leaf of a rose was deficient, except the stipules 

 and a small portion of the petiole. (See abortion.) 



Meiophylly. A diminished number of leaves in a 

 whorl occasionally takes place ; thus, in some of the 

 Stellatoi, and frequently in Paris quadrifolia, the 

 number of leaves in the verticil is reduced. Care must 

 be exercised in such instances that an apparent dimi- 

 nution arising from a fusion of two or more leaves be 

 not confounded with suppression.
