from those of the parent plant. This has been observed in three 

 cases. 



Escot (PI. XIII, fig. 1) has flowers white with a large purplish red 

 blotch on each petal. It is characteristic of the variety that the petals, 

 especially the two dorsals, roll back more or less. A plant gave off a natural 

 "sucker" (from a root) which bore flowers as shown in PI. XIII, fig. 2. They 

 are larger than type (70 mm. across the largest flower against 62 nmi. in 

 the parent); and flat, showing no disposition to roll back. The peripheral 

 areas of the petals are pinkish, not white, and the blotches much redder 

 than those of type, a feature insufliciently i-endered in the coloured 

 figure as reproduced. A root-cutting has since been raised from Escot, 

 and its flowers agree with those of this sucker. The rolling-back of the 

 petals in the parent is perhaps due to strain produced by the greater 

 size of the flower proper to the included "core." The root-cuttings are 

 somewhat taller than the type. 



Mrs Gordon has flowers white and pink as shown in PL XIII, fig. 3, 

 with guide-marks of the dorsal petals only lightly represented. Three 

 root-cuttings are all alike (PL XIII, fig. 4), have much more colour, 

 a full pink, on all petals, and in addition deep crimson guide-marks. 

 These root-cuttings are very like and probably identical with the variety 

 called "Cardiff." Both type- and root-form^ may have more colour than 

 appears in the figures, especially in newly opened flowers, but the 

 relative amounts of colour are correctly represented. In Mrs Gordon the 

 guide-marks are only distinguishable as " ghosts." 



Pearl is a white semi-double Regal (PL XIII, fig. 5) having small and 

 evasive purple patches in the area of the guide-marks. Sir W. Lawrence 

 kindly gave me a plant of Pearl having a large branch with flowers 

 heavily marked with red (PL XIII, fig. 6) much as in the varieties kno^vn 

 as Mme Thibaut and Emmanual Lias (? synonymous). Three root-cuttings 

 raised from Pearl all have exclusively flowers of this coloration. Doubling 

 in parent and the root form is similar in degree. Pearl itself has been 

 grown here on a fairly large scale. At various times three flowers have 

 been produced by it with a patch of red as shown in PL XIII, fig. 7. These 

 patches must be regarded as indicating a break through of the under- 

 lying tissue, like the green patches so often seen on the leaves of some 

 variegated chimaeras composed of a white cortex overlying a green core. 



The three examples mentioned are the only cases in fancy Pelar- 

 goniums of root-cuttings differing from parent plants up to the present. 

 Numerous varieties have been tried, but at first we were not very 

 successful in raising such plants. The technical difficulties have now
