plants had shown so much prima-facie evidence as regards 

 their multiple parentage that a Silver Floral Medal was 

 awarded. 



From the illustrations the author cannot think that any 

 one will doubt that all four characters have been reproduced. 

 This is one of the strongest evidences that all the four 

 parents have participated in their production. 



It may be mentioned that although we produce the 

 combination of three or four varietal forms, none are alike, 

 most very dissimilar, a proof that the number of sperms 

 varies. 



EXPERIMENT NO. XII. 



In 1888 five varieties of Scolopendriums were sown 

 together, viz., undulatum, muricatum, keratoides, spirale (Figs. 

 20, 21, 25, 26), and kraspedoumenon (Fig. 31) (with a ridge 

 near the margin, occasionally having a forked apex). These 

 came to maturity in 1891. 



Two of the seedlings are figured. One of these, Angela 

 (Fig. 32), shows the characters of all five parents, being 

 undulate, muricate, marginate, and capitate, with twisted 

 divisions ; the other (Fig. 33) is only muricate with twisted 

 undulations, and slight crest (the characters of four parents). 



Four of the parents are illustrations to Experiment No. 

 7 ; the fifth, i.e., kraspedoumenon (Fig. 31), is represented here 

 together with two of seedlings named Angela and Hydra 

 (Figs. 32 and 33). 



Multiple parentage is very apparent. 



EXPERIMENT NO. XIII. 



At the same time as spores were sown in Experiments 

 Nos. 7 and 8, separate pans were sown as follows with four 

 of the varieties used in Experiment No. 7 : —
