NOTE. 



DuBiNO the progress of the foregoing pages through the press, 

 several additional illustrations of particular malformations have come 

 under notice. Some of the more important of these may here be 

 recorded. 



Fasciaiion (see p. 11). The following plants may be added to the 

 list: Acer ei-iocarpum, Arabia albida, Brassica olei-acea, var., Gxuirea, 

 sp., Artaboti-ys sp. In all, with the exception of the first-named, the 

 fasciation occurred in the inflorescence. In some species of Artabotrys, 

 indeed, fasciation and curvation of the inflorescence are common. 



Synanthy (p. 39). Several additional instances of adhesion of two or 

 more flowers in Calanthe vestita, C Veitchii, and other forms of this 

 genus may be cited. These furnish further illustrations of the much 

 greater liability of some plants to particular changes as compared with 

 others. Scilla bifolia, Gagea arvensis, and Viola odorata may be added 

 to the list of synanthic plants. 



Alterations of placentation, &c. (see pp. 98, 483). M. Casimir De Can- 

 doUe, in a letter to the author, dated March 8th, 1869, thus wi-ites of the 

 existence of a double row of cai-pels in Pyrus spectabilis and Crataegus 

 Oxyacantha, " a longitudinal section of a double flower of Pyrus specta- 

 bilis shows two rows of carpels, placed one above another. The aiTange- 

 ment of the vascular bundles shows that the upper row is external in 

 relation to the lower series. The carpels of the latter are wholly 

 coalescent as in a peai*, while those of the upper verticil are only par- 

 tially coherent or sometimes quite distinct. The placentation is con- 

 stantly axile in the inferior row and parietal in the upper one. The 

 number of ovules in each carpel of the superior row varies greatly, 

 and they are often,, but not always, inserted in two longitudinal ranks', 

 as is constantly the case in the lower carpels. Double flowers of 

 Crataegus Oxyacantha present the same anomalies." For analogous 

 instances in Digitalis, see p. 98. See also p. 380, Saxifraga. 



Prolijication, p. 120. A. P. De Candolle, " Organographie Vegetale," 

 tab. 40, figures an instance of suppression of one lobe of the ovary in 

 Iris chinensis, and of the pi-esence at the base of the flower of an
