THE ORCHIDS OF NEW ENGLAND. -^j 



to cut away the old stems in autumn and to give a slight 

 top-dressing of the same mixture." The frame was covered 

 with mats in winter and great pains taken with the drain- 

 age ; excessive moisture in his, as in Sweet's judgment, doing 

 more injury than cold. 



Among those in New England who make a business of culti- 

 vating our native Orchids is Mr. Edward Gillett of Southwick, 

 Mass., who tells me that he has been most successful with the 

 following species : Cyps. arietinum, pubescens and parviftorum ; 

 Habcnarias virescens, Hookeri, ftmbriata, psycodes ; Goodyera 

 pubescens ; Spirant lies cernua and gracilis ; Aplectrum Jiycmale. 

 " Calypso borealis, obtained from Oregon, does well in sand, the 

 wire worms eating the bulbs badly if planted in anything else." 

 W. L. Foster, of Hanover, Mass., has succeeded well in raising 

 the Cypripediums in a partially shaded border of leaf mould 

 mulched with leaves. " C. acaule, however, always dies out 

 within a year or two. I think it might do better if seed were 

 sown in soil similar to that in which it naturally grows. 

 Calypso has been tried in various situations, but I have never 

 seen it after the second year, and others who have tried to 

 grow it have had the same experience. A friend has grown 

 many species with fair success in a brick tank filled with 

 swampy soil, mulched with sphagnum and kept moist." F. H. 

 Horsford, Charlotte, Vt., has the following "hardy " species on 

 his Trade List : Both Orchises ; Habenarias, hypcrborea, dila- 

 tata, obtusata, Hookeri, orbiculata, ciliaris, lacera, psycodes, fim~ 

 briata ; the three Goodyeras ; Spiranthes, Romanzoviana, cernua, 

 graminea and simplex, Listeras, cor data and convallarioides ; A. 

 bulbosa ; Pogonias, ophioglossoides and verticillata ; C.pulchellus ; 

 Calypso borealis; T. discolor; both species of Liparis ; A. 

 hyemale and all the Cypripediums. 



C. acaule appears to be invariably disobliging. Mr. R. A. Salis- 

 bury* as far back as 1812, planted it in peat earth mixed with
