Liparis Loesellii (L.) Richard 



more or less frequent in the southern part. The plant is very inconspicuous 

 and doubtless it is more abundant than our records indicate. It evidently 

 prefers a slightly acid soil and is generally found in deep humus in beech 

 or white oak woods and more rarely in black and white oak woods. In 

 Putnam County about 3 miles northwest of Greencastle, on June 3, 1910, I 

 found it in a 19-year old Catalpa planting that had been first cultivated 

 to strawberries and later abandoned. Here the plant was growing by the 

 hundreds. In addition to the counties shown on the map it has been 

 reported from these counties : Lake, Union, and Vigo.

2. Liparis Loeselii (L.) Richard. Loesel Twayblade. Map 724. The 

 majority of my specimens were found in sphagnum in tamarack bogs and 

 in open boggy places. It is very local and is restricted to the lake area. In 

 addition to the counties shown on the map it has been reported from Fulton, 

 Kosciusko, La Porte, and Marshall Counties. It has already become very 

 rare.

1560. TIPULARIA Nutt. 



1. Tipularia discolor (Pursh) Nutt. {Tipularia uni folia (Muhl.) BSP.) 

 Cranefly Orchid. Map 725. This species is restricted to our southern 

 counties but it may have a wider range than the map shows. I have a 

 memorandum that I saw it in Brown County but I did not preserve speci- 

 mens. In 1938 Benjamin W. Douglass wrote me he found it near Trevlac. 

 The leaves disappear before flowering time and look much like those of 

 Orchis spectabilis or those of Aplectrwm, hyemale. Tipularia may 

 easily be distinguished because the lower surface is purplish instead of 

 green. One does not usually collect leaf specimens but in this species a leaf 

 specimen makes a record as authentic as a flowering one. I am of the 

 opinion that it will be found all over the unglaciated area, but very locally. 

 Where it is found it is usually somewhat frequent but it is so inconspicuous
