The amphigaean genus llabenaria is well represented in the 

 state, but in number of species, twelve, rather than in frequency 

 or distribution. H. bracteata, H. flava, H. hyperhorea are found 

 occasionally ; H. claveUata, the most widely distributed of the 

 genus, is in thirty towns and in every county except Fairfield. It is 

 found usually, not invariably, in small colonies in shallow, tempo- 

 rary pools in open woods, or on the borders of sluggish brooks. 



H. orhiciilata is found, sparingly except in Hartland, in nearly 

 all the towns of the northern border. H. Hookeriana is frequent on 

 one hill in Ellington and is found occasionally in four of the eight 

 counties of the state, both northerly and southerly. 



There are in the state five species of the fringed Habenarias, 

 H. lacera being the most widely distributed, H. cilaris probably the 

 most abundant in individuals though occurring in gradually reduced 

 numbers in three shore towns ; it has been detected also in an open 

 field in Moodus, Middlesex County, about sixteen miles inland. 

 H. hlephariglottis was abundant in a thicket in South Windsor, 

 but is disappearing rapidly. It has been reported from five other 

 towns. H. psy codes occurs infrequently in all parts of the state, 

 quite as often in open, low woods as in fields or swamps, never in 

 large groups. H. fimbriata is even less frequent, is found chiefly 

 in Hartford County. Orchis spectahilis is well distributed in four 

 inland counties and abundant in one town in Litchfield County. 



All three species of Peramium are found in one w^ood in Wood- 

 stock. P. piihescens is in almost every town as noted above. 

 P. tesselatum is well distributed in the northerly sections and is 

 sometimes abundant, notably in Norfolk. Its anthesis is sometimes 

 ended as that of P. piihescens in the same locality is beginning. 



Arethusa is vanishing; there are small groups in Glastonbury 

 and Litchfield and, it is reported, in Pomfret. Twenty years ago it 

 was in Thompson also. Fifty years ago it was abundant in Hamden. 



Liinodoruiii and Pogonia ophioglossoides are abundant in 

 widely separated places, occasionally in damp roadsides, never, it 

 seems, both found in large numbers in the same swamp. In one 

 very wet bog in Marlboro, there are hundreds of Pogonia, very few 

 Limodoruni; in a grassy swamp in Simsbury near the other corner 

 of Hartford County, the reverse is true, Liinodoruui being even 

 more abvmdant.
