 FAMILY 113. ERICACEAE. HEATH FAMILY 



584. LEATHER-LEAF; DWARF CASSANDRA 



CHAMAEDAPHNE CALYCULATA (L.) Moench 



Common in Hawk's marsh, as a low shrub forming a zone be- 

 tween the tall shrubs and the grasses. Found also at the tamarack 

 west of the lake, but not so abundant. Passing out of flower by 

 May 20. 



Although not so handsome or striking as Pieris floribunda, a 

 relative that has found a well-deserved place in landscape gardens, 

 this little shrub has many charms and a place of its own in the 

 scheme of decoration of the swamps. It is an exceedingly hardy 

 plant, growing as far north as Newfoundland and Alaska; still it 

 is what the landscape gardener calls a "broad-leaved evergreen," 

 a group represented by the holly, box, and the like, and usually liv- 

 ing in only mild climates. In addition to its graceful sprays of 

 foliage, consisting of leaves becoming gradually smaller and smaller 

 toward the tips of the branches, and which become purplish in win- 

 ter, one of its greatest charms is its racemes of flower buds which 

 are conspicuous throughout the winter, so well advanced in develop- 

 ment that they seem ready to bloom at any time. 



585. WILD ROSEMARY; MARSH HOLY ROSE; MOORWORT 



ANDROMEDA POLIFOLIA L. 



Rather abundant among the sphagnum of Hawk's marsh. A 

 low, rather inconspicuous evergreen shrub. The leaves curl up 

 strongly along the margins, especially in cold weather. 



There is an air of refinement and daintiness about the marsh 

 rosemary, with its whitish rolled-up leaves and chaste, drooping 

 vase-shaped blossoms, that makes the finding of it an unusual pleas- 

 ure. It is a hardy plant so far as temperature and rigorous winters 

 are concerned, growing as far north as Alaska and British Colum- 

 bia. It is a pity it does not grow in our marshes and swales as 

 well as in the cold tamarack bogs. Noted in blossom in Hawk's 

 marsh about the middle of May (May 20). 



586. TRAILING ARBUTUS; MAYFLOWER 



EPIGAEA REPENS L. 



Rare; only a few plants found in a sandy woodland near some 

 tamaracks southwest of the lake. Generally speaking this is a rare 

 species in the state, being found only in a few of the northern 

 counties and in Monroe county, where it is abundant in one locality.
