Goodyera pubescens, R. Br. ; not rare ; Stissing Mt. ; very abun- 

 dant in Briggs' Woods, beyond Bethel. 



Spiranthes latifolia, Torr. ; not common : S. end of Thompson Pond 

 with Ophioglossum vulgatum; along Trout Brook and Hoys- 

 radt Marsh. — S. cernua, Richard. ; common, — S. gracilis, Bigel. ; 

 not common, but abundant in Ham's Ravine Woods, and open 

 places, Stissing Mt.- — S. simplex, Gray; rare; Ham's Ravine 

 Woods.— {G. M. Wilder and L. H. H.) 



Arethusa bulbosa, L. ; very rare; only a few specimens in L. Smith's 

 bog, G. M. IV. ; in Cranberry Marsh, along Van Tassel Pond, 

 June, 1878. 



Pogonia ophioglossoides, Nutt. ; rather common ; Fingar Cranberry 

 Marsh; Drosera Swamp, S. E. of Attlebury, etc. This plant 

 appears almost always to be accompanied by Calopogon pul- 

 chellus. — P. verticillata, Nutt.; rather scarce; abundant on 

 Stissing Mt. about Mulberry Meadow, but very seldom found 

 in flower ; the plants appear to be sterile. 



Calopogon pulchellus, R. Br. ; quite common ; in same localities 



with Pogonia ophioglossoides. 



Microstylis monophyllos, Lindl. ; with Lipparis Loeselii, in swamp in 

 G. Lasher's Jno. Fingar Woods, Gallatin, June, 4, 1878. — M. 

 ophioglossoides, Nutt. ; rare ; in and about Moss Flat, south- 

 west of Harrietta Falls, Stissing Mt. ; Geo. Rowe Woods, 

 Gallatin. 



Liparis liliifolia, Richard. ; frequent on N. end of Stissing Mt. — L. 

 Lceselii, Richard. ; very rare ; only detected in Pet. Lasher's 

 Swamp. 



Corallorrhiza odontorrhiza, Nutt. ; sparingly found in several of our 

 woods ; Ham's Ravine Woods. — C. multiflora, Nutt. ; common 

 on mountain, and in all our woods. 



Aplectrum hyemale, Nutt.; this plant, I have never found in Pine 

 Plains, but I have good authority for its being found here fre- 

 quently, thirty and more years ago, in someof our large swamps, 

 by the botanic physicians and others ; those swamps have 

 since been largely cut away and partially drained and the plant 

 may now be exterminated, for high cultivation is certainly the 

 bane to many of the rarest and shyest plants of our native 

 flora. Another cause of its rapid extermination here may 

 arise from its being eagerly sought after by the vulgar and sim- 

 ple-minded, in early times, on account of its reputed properties 

 as a philter. 



Cypripedium parviflorum, Salisb. ; common ; Mill Hill, Risedorf 

 Hill, etc. — C. pubescens, Wild. ; not so common; swampy 

 grounds on Stissing Mt. — G. spectabile, Swartz ; rather common ; 

 abundant in Tamarack Swamp near Halstead Station ; Pogonia 

 Swamp, S. E. of Attlebury ; Tamarack Swamp W. of Croghan 

 Hill, Drowned Lands, etc. — C. acaule. Ait.; rather common on 

 upper and southern parts of Stissing Mts. and in a few of the 

 rich woods and swamps. 



Amaryllidace.e. 

 Ilypcxys erecta, L. ; common.
