6 FIELD AND FOREST. 



ciniata, it seems to hold itself distinct. The raceme is longer and laxer 

 and the petals longer than laciniata. The cauline leaves are alternate, 

 usually the upper two in near proximity, and the third at a distance 

 lower. The leaf segments are less cut than in laciniata. The radical 

 leaves are so delicately attached to the root-stock that it' is difficult to 

 secure specimens in perfect condition. 



CoRYDALis FLAVULA, Raf. — This species is found here in great 

 abundance in company with Dentaria. It is' taller than C. aurea, 

 which has not yet been observed here, but it is not so rich in the color 

 of the flowers. 



Viola pedata, L., var. bicolor, Gr. — This variety is more showy 

 than any other of our native violets, and being perfectly hardy is wor- 

 thy of more cultural attention than it receives. It is inferior to the 

 pansy only in the size of its flowers, and probably these might be en- 

 larged and improved by cultivation. 



PoA BREviFOLiA, Muhl. — This species vies with Poa annua in early 

 flowering. It is one of the most graceful of our Poas and when grow- 

 ing under favorable circumstances, becomes i^ to 2 ft. high. It pre- 

 sents several variations from the type, as in the number of the branches, 

 which in some of the specimens are 3-5, in having both glumes acute, 

 and the lower palet prominently nerved. The sheaths are sometimes 

 quite scabrous. 



Potomac-side Naturalists' Club. 



April 12th, 1875, (186/A meeting.) 

 Prof. Chickering read a paper upon the Alpine Flora of New Eng- 

 land, illustrated by specimens. In his enumeration were embraced 

 mainly those plants growing above an altitude of 2500 feet, though 

 quite a number of plants found around the base of the mountains might 

 be included in the flora of the region. It is also confined to the gran- 

 ite regions of the White Mountains, and Mt. Katahdin, omitting sev- 

 eral species occurring in the limestone formations of Vermont. 



Among them may be mentioned Cardaminc hellidifolia, Viola palus- 

 ti-is, Paronychia argyrocoma, Ai-enaria Groenlandica, Potentillafrigida, 

 Rubus Chamcemonis, Saxifraga oppositifolia, S. rivulan's, S. stellaris,
