NOTES ON SOME CURIOSITIES OF ORCHID BREEDING. 481 



(3) Cypripedium Calceolus ? x Phragmipedium x Sedenii 

 candidulum £. Crossed March 18, 1897. Pod ripened August 15, 

 1897 ; 166 healthy seeds. (Orch. Bev. v. p. 365.) 



(4) Paphiopedium Exul ? x Cypripedium Calceolus S • Crossed 

 April 16, 1897. (Since ripened 597 good seeds. Orch. Bev. v. 

 p. 365.) 



(5) Angrsecum sesquipedale $ x Lfelia purpurata (? . Crossed 

 May 9, 1897. Fine pod 4^ inches in girth, opened July 31, 1897, 

 eighty-three days after pollination ; no seeds, ovules shrivelled. 

 Interior of the pod full of fluffy, silky, downy threads or fibres, 

 loosely woven together. 



(6) Cattleya Mossire ? x Angraecum sesquipedale . Crossed 

 May 9, 1897. Pod swelled to 2£ inches girth ; withered away, 

 July 1, 1897. Pollen tubes had grown 2\ inches down the 

 column, and had reached the ovary ; ovules undeveloped. 



Since then I have set two pods of Oncidium incurvum $ x 

 Odontoglossum crispum 3 , swelling rapidly. Crossed August 11, 

 1897. 



A summary of my notes was republished in M. Cogniaux's 

 Dictionnairc Iconographiquc des Orchidees (Chronique Or- 

 chideenne), June 1897, and in the following number M. Georges 

 Mantin, of Chateau de Belair, Olivet, Orleans, France, was 

 good enough to give his opinion on these generic crosses, com- 

 paring them with others made by himself on similar lines, such 

 as Paphiopedium x Phragmipedium, Cypripedium x Paphiope- 

 dium, Cypripedium x Phragmipedium, Oncidium Papilio crossed 

 with self and with other Oncidiums, Lockhartia x self, and 

 with Oncidiums, &c. M. Mantin obtained pods and even 

 seeds from these crosses, but had never been able to raise any 

 plants. (" J'ai observe parfois des grossissements prolonges de 

 l'ovaire. J'ai meme obtenu des graines de ces croisements plus 

 ou moins rationnels, mais il n'est jamais rien leve de ces semis.") 

 M. Mantin also mentioned that he had sown seeds of more than 

 forty pods of Paphiopedium (Cypripedium) barbatum and allied 

 species crossed with Cypripedium Calceolus, but none ever grew. 

 (" J'ai serve plus de 40 (je dis quarante) gousses a graines de 

 C. barbatum et especes voisines f£condees par C. Calceolus. Je 

 n'ai jamais constate qu'une seule graine ait germe.") Further, 

 M. Mantin expresses the opinion that in the above curious 

 crosses I shall reap the wind instead of seeds, and will be very
