24 Transactions of the 



two forms, if they do not graduate into each other, but remain distinct in the neighbor- 

 hood of each other, they should be regarded as species. Bofanically the most obvious 

 difference between the apple and the pear, is in the fruit. Apples are globular, oblate, 

 prolate and conical, but never o6-conical, the form of the pear. Even an intermediate 

 form might be a hybrid, and would not prove the other two to be only varieties. Among 

 animals, hybrids rarely occur without the agency of man. Why should we not expect 

 that, where fertilization depends on the wind or the position of the stamens and pistils, 

 hybridization should be extremely rare? But when it depends on insects or Mr. Rogers, 

 it should be more common. 



An interesting article on hybridization and cros.sbreeding may be found in the Report 

 of the Department of Agriculture for 1867. 



Bearing on the same subject is a little experiment of mine. In 1870, 1 planted seed of 

 a small winter squash, — name not known — oblong, fluted, dark green or orange, or partly 

 both, about five inches long, and three or four in diameter. One or two of the resulting 

 plants bore squashes of the same form, but twice as large, and of the color of the scalloped 

 flat summer squash. I regarded them as hybrids, and wanted to see if the seeds would 

 vegetate. The next year I planted them, and they came up well and bore, but every 

 squash was like the oblong parent. 



I have several times tried to raise pawpaws, planting the seed in the fall without dry- 

 ing, both in and out of the fruit, but without success. Last spring, I tried the plan recom- 

 mended for the Osage orange. I took seed that had been buried during the winter, soaked 

 them two or three weeks, changing the water, planted them in a shady place, and watered 

 them often. They waited so long that I despaired of them, but in June or July they ap- 

 peared. 



I have raised mulberries from seed by washing the seeds soon after it was ripe, planting 

 it in a shady place in earth not clayey, and watering it every evening. It came up in 

 about ten days. 



I have this year found the artichoke, Helianthus tuberoses, growing spontaneously in 

 my garden. Last year I tried to analyze it, but failed because the Helianthus tuberoses 

 being called an exotic, in both Wood and Gray, I passed it by. 



H. lentriularirt, said by Mr. Hall to grow in Kansas, I have not recognized till this year, 

 because I had no description of it. I now find it abundant. It is one of tlie few that 

 have a brown disk. 



Hitherto, so far as I know, no representative of tiie large order Ericaceae has been 

 found in Kansas. This year one, the Monotropa uniflora, or ghost flower, has been found 

 at Vinland, by Miss Sarah Cutter.
