as Orchis, where a new tuber is formed by the side of the old one 



at some considerable distance, as in Herminium; and the tuber 

 which has flowered dies. The tuber is therefore a winter annual. 

 Of course all these ought not to be confounded with the true 

 perennials, where the same root lives and flowers at least several 

 years in succession. DeCandolle's terms mono- and poly-carpic 

 will not do, for they convey another idea. Mono- and poty-tecous, 

 as suggested by A. Gray, are better, but here we do not distinguish 

 between Agave and Brassica. And he has not attempted to dis- 

 tinguish these from Orchis (except by calling the latter perennial, 

 as we all do), or Orchis from Fragaria.— C. C. Babbington in

A Botanist's Trip to " The Aroostook." No. 2. — On June 

 6th. '81, my Western friend and I left Orono (Penobscot county) 

 for Northern Maine, by way of the railroad as far as Mattawam- 

 keag, where we passed a day pleasantly in following the banks of 

 the river for flowers. On the stream of the same name I saw 

 for the first time Alnus viridis, which afterwards became a daily 

 occurrence; also Cratagns coccinca, with three of its forms ; pyri- 

 folia and mollis being quite abundant, as I found in September, 

 when the fruit had matured. We traveled by stage to Patten 

 (still Penobscot county), a distance of 38 miles through a most 

 delightful country, but saw no new weeds by the roadside. At 

 this place I procured seven of the plants, which were gathered on 

 the Aroostook river the previous year in fruit. Perh.ips this 

 locality may be called the boundary line of some of these plants, as 

 they do not grow either at Orono or Mattawamkeag (in writing 

 this article I shall only speak of what I saw), but at Patten they 

 were abundant. One morning we came across a large number ot 

 Cypripediums, among which was a purple acaulc with two perfect 

 flowers growing back to back. The greater part of them were 

 pure white with yellow-green sepals and petals. After a week 

 spent there, taking with us 16 new sketches and a large package 

 of pressed plants, we staged it to Ashland, a ride of 48 miles. 

 The beauty of the country beggars description. For a distance 

 of 12 miles we were in full view of Mounts Ktaadn, Double and 

 Round Top. A good-natured driver told us the names of all the 

 hills, streams and ponds. It may seem strange to the reader that 

 we discovered no new plants in this long ride, but the only nov- 

 elty spied was a rose-pink / / ',• / //// <u lantanoid, s. - Inn 'am hu r C an-

 is quite common, but straggling and partially dead. Acer Bcnnsyl- 

 vanicum and spicatum is the prevailing underbrush in many of the 

 forests. But for our own voices the stillness would have been 

 oppressive; for a distance of many miles that day we did not find 

 an opening. The mail agent said that between us and Canada on
