characters that were wholly lacking in either parent. These new characters 

 were unusual colors, shapes, wartiness of the fruit and attributes of vine. 



Hybrids of two species. In all the work with Cucurbits, numbers of 

 attempts were made to combine the three species, C. Pepo, C. maxima and 

 C. moschata. It is a common notion amongst gardeners that these three 

 species intercross interminably. All efforts, however, to combine the three 

 species have failed, and the speaker is convinced that under common garden 

 conditions none of these species habitually hybridize. 



He became convinced, however, that it is possible to amalgamate 

 C. moschata with C. Pepo, and a definite result was secured in this direction 

 in 1892. The result of many pollinations was seven fruits of the following 

 progeny : 



Common ornamental gourd (Cucurbita Pepo} by the Japanese Crook- 

 neck (C. moschata). 



The Fordhook bush pineapple squash (C. Pepo) by Butman squash 

 (C. maxima). 



The Connecticut field pumpkin (C. Pepo) by the Japanese Crookneck 

 (C. moschata). Of these two fruits were secured. 



Japanese Crookneck (C. moschata) by Red Etampes pumpkin (C. 

 maxima) . 



Boston Marrow squash (C. maxima) by Green Striped Bergen bush 

 scallop (C. Pepo). 



Early Sugar pumpkin (C. Pepo) by Red Etampes pumpkin (C. maxima). 



In all these crosses there was no immediate effect of pollen. In four 

 of these fruits, although the fruits themselves were well grown, there were 

 no perfect seeds. In some cases the seeds were full grown and plump, but 

 they were empty. Only three fruits gave seeds. These were the gourd 

 crossed by the Japanese field pumpkin and two fruits of the Field Pumpkin 

 crossed by the Japanese Crookneck. All these were crosses between C. 

 Pepo and C. moschata. From the Field Pumpkin crossed by the Japanese 

 crookneck fruits, eighty-eight plants were grown. These fell into about 

 eight types, although there were only four or five well marked forms. Most 

 of them were like a small orange pumpkin. Some were small green 

 pumpkins. None of them showed any influence of the staminate parent, the 

 Japanese, except that in a few the scar of the blossom end was very large, 

 which is usually not the case in the varieties of the pure Cucurbita Pepo. 

 One of the forms simulated a bush scallop squash of light lemon color. 

 One was striped. All of these forms had the fruit stems of Cucurbita Pepo. 



The details of these progeny (of Field Pumpkin by Japanese Crookneck) 

 are given in the following notes : 



Nos. i, 2, 3, 4 and 5 were much alike. They were flattish, deep orange 

 pumpkins. No. 3 was marked somewhat green. 



Nos. 6 and 7 were small, hard, smooth, rather long-stemmed forms, 

 yellow-orange. 



No. 8 was pyriform and green-striped. 



No. 9 was cream-color and approached the bush scallop type. Nearest 

 white of any. Somewhat obconic.
