Metamorphosis : Heteeosepalodt. 



As showing that the spur in the Indian cress {Tropseolum 

 inajus) is part of a sepal, and not of the receptacle, a flower 

 belonging to Col. Eawson was seen in which a foliaceous sepal 

 "bore a spur situated well above its base. 



METAMOitPHOsis : Sepalodt. 



Some apples were received from Miss E. A. Portal, of 

 Over Wallop, Hants, in which the corolla and some of the 

 stamens had become transformed into sepals, each with a 

 swollen fleshy base like the normal ones constituting the pome 

 below. Withered remains of some stamens and styles 

 occurred in the "eye" at the top. The axis in the base of 

 the pome had slightly elongated, carrying the core, which was 

 poorly developed and contaioed a iew withered undeveloped 

 pips, to the top of the fruit. The fruit is stated to be in some 

 cases more elongated and conical. 



It is not unlikely that the phenomenon here described is 

 the same as that shown by the abnormal pears detailed in a 

 previous section under " Proliferation." If so, the theory of 

 Wittmack with regard to the "storeyed" pears must be held 

 to be the correct one, viz., that the "storeys" represent 

 corolla, androecium, and styles respectively, changed into 

 sepals. And the theory propounded in this work, that they 

 represent secondary and tertiary pears due to proliferation, 

 must be given up. 



The appearance presented by such an apple as this is a most 

 nnusual and peculiar one. It shows the same phenomenon as 

 that exhibited by the seedless Colorado apple described on 

 pp. 13-14, but in that case the corolla only had undergone 

 the change. 



Metamobphosis : Petalody op Stamens. 



A flower of a rhododendron (Ascot Brilliant x Thomsoni), 

 sent to Kew by Sir E. G. Loder, showed a deviation rare in 

 this plant. The withered corolla bore curious fleshy, crimson, 

 waved outgrowths at its base; the axis of the flower was some- 

 what elongated, and all the stamens, save one or two, changed, 

 wholly or partially, into large petals, of which the lower were 

 free, the others united to form gamopetalous hose-in-hose 

 corollas ; they had also increased in number., The flower was 

 more than two months out of season (late), and had developed 

 from an axillary, not a terminal, bud.
