Aqiiilegia Canadensis, L., van FLAVIFLORA, n. var. {A. Jiavi- 

 Jlora, Tenney, Amer. Nat., i., 389). On the isth of May, 1866, 

 Prof. Sanborn Tenney, of Vassar College, found a yellow-flow- 

 ered Columbine on the high ground west of the Hudson, and 

 opposite the city of Poughkeepsie, which he described in the 

 first volume of the American Naturalist as Aquilegia flaviflora. 

 On May 17th of the succeeding year he collected the same vari- 

 ety near the same place, and proposed to try to raise the plant 

 from the seed. Of his farther observations I find no record. 



On May 24, 1885, during a Club Field Excursion at Sea- 

 bright, Monmouth County, New Jersey, the plant was found in 

 considerable abundance on the south bank of the Navesink 

 River, along the top of a bluff some twenty feet above the water 

 level. It grew there with the ordinary red-flowered, typical form, 

 with which its showy flowers formed a marked and beautiful con- 

 trast, both being remarkably luxuriant. Associated with them 

 was Cerastiiim arvense, L., and near by grew Smilacina stellata, 

 Desf , neither of which had been noted so far south along the 

 coast. I removed a plant of the yellow Aquilegia to a garden 

 where it has since bloomed every year, maintaining its character. 

 I have not been able to detect any other differences between it 

 and the type except that the whole plant is of a light yellowish 

 green instead of the usual reddish purple hue of the young plants 

 of the ordinary form. 



Cerastium Texanum, n. sp. Stem slender, 15-20 cm. high^ 

 pilose, especially towards the base, branching dichotomously
