320 Lake Maxinkuckee, Physical and Biological Survey 

 375. MEADOW BITTER-CRESS; CUCKOO-FLOWER 



CARDAMINE PRATENSIS L. 



One of the most attractive of the cardamines, with its tall stem 

 and comparatively large white flowers. Common, scattered through 

 moist open meadows such as the flat west of the grist-mill and 

 Green's marsh. In flower from May 5 on. 



376. PENNSYLVANIA BITTER-CRESS 



CARDAMINE PENNSYLVANICA Muhl. 



Common in swamps and wet places. Collected in flower near 

 the shore of the lake, in the low woods by Overmyer's May 25, 1901. 



377. PURPLE CRESS 



CARDAMINE DOUGLASSII (Ton.) Britton 



Rather common, especially on the northeast side of the lake 

 about the low margins of marshes and in wet woods generally. 

 It is common throughout the state in wet woods. In early 

 spring the plant shoots up quickly from a sort of tuber. The flower 

 buds, first as minute little bells, gradually enlarging and show- 

 ing glimpses of pink are among the earliest promises of spring 

 flowers, though several other plants not so prominent in bud, bloom 

 earlier. In flower April 19, 1901, abundantly in flower April 30. 



378. SPRING CRESS; BULBOUS CRESS 



CARDAMINE BULBOSA (Schreb.) B. S. P. 



Once common throughout the state in rich woods, especially in 

 wet places, but disappearing as these are drained, cleared or pas- 

 tured. A very hardy plant, the naked flowerbuds showing ex- 

 ceedingly early in spring. One of our best known spring flowers. 

 April 19, 1901, in flower on the east side of the lake. April 30, 

 abundantly in flower. May 5, collected in Green's marsh. 



379. CUT-LEAVED TOOTHWORT 



DENTARIA LACINIATA Muhl. 



Not so abundant as the cardamines, but growing in similar 

 situations; partial to rich leaf-mold. April 11, 1901, in large bud 

 east of the lake; April 18 in flower in Vajen's gulley; April 19, 

 27 and 30, still continuing in bloom. It bears yellow fusiform 

 tubers resembling miniature sweet potatoes. These have a pleasant 

 mustard-like flavor.
