110 ~ Ninth report. 



the lateness of its bloom. H. appendiculatum and H. Virginieum asso- 

 ciate with the former, the former ver}^ scarce. In the fall Leptamniiim 

 was eA'erywhere, an odd and interestina; form. 



An interesting offshoot of this beech flora is found on the Magician islands 

 "Maple/' "Hemlock" and "Rattlesnake." The former has lost its virgin 

 character and has not, therefore, been ex]")lored, but the other two are most 

 remarkable when we consider that neither is more than one-quarter mile 

 from the oak-clad main land. Here beech, maple, basswood, ironwood, 

 blue beech, white pine, red cedar (now extinct), hemlock, paw paw, dog- 

 wood and white elm, Avith a few butternut, tulip trees, cherry, birch, aspen 

 and red maple make the forest growth. It must be' borne in mind that the 

 beech forest is five miles distant, yet here are Leptamnium, Aplectrum, 

 Bicuculla Can., Deutaria laciniale, Sambucus pubens and actasa alba. A 

 perfect haven it seems to prove for the latter judging by the number and 

 perfection. A few isolated and peculiar species are found on the two islands. 

 On "Hemlock," and giving the name, are a dozen fine Tsugas. The south- 

 western limit, I am led to believe. An interesting bit in connection with 

 the inter-relation of plants is that on the old hemlock stumps the striking 

 fungus Fomes lucidus grows. I have met it once before in the hemlock 

 woods of Canada, and its association seems to be with this species. The 

 fern Phegopteris Phegopteris is found here and nowhere else. Carex scab- 

 rata is common and peculiar. Cy]5ripedium hirsubum is abundant on both 

 islands, but exceedingly rare in all other localities. 



On "Rattlesnake" island a fine clump of Deutaria diphylla is the only 

 station. Equisebum pratense is common. Each island has a flora of 

 about 150 species, many of which are very common and luxuriant, and ap- 

 parently find the best of environment in which to groAV. 



In the northeast part of the survey are two isolated areas of v\^hite pine, 

 one consisting of virgin timber, so dark and dense thaj: practically nothing 

 grows. One small area of Coptis makes a fine display in May. Two miles 

 southeast is Pine Lake, with a large wooded island abundantly covered with 

 a mixed growth of timber in which pine ])redominates. Here is an ideal 

 spot for Epigea, but it is wanting. Mitchella fairly carpets the ground. 

 Lycopodium obscurum abounds, and L. lucidulum occurs 07ice. This re- 

 gion has not been thoroughly explored and promises some interesting finds. 



The beach flora is limited to the lakes "Dewey," "Cable" and "Crooked," 

 and its mate "Round," and to a few ancient beaches now bordering marshes. 

 Here the plants are found in distinct zones, and form a very peculiar associa- 

 tion. Three of these floral bands properly belong to the water forms, and 

 from lakeward towards the shore are as follows: Castalia odorata about 1-3 

 rods wide; Pontederia, 1 rod; Euthamia caroliniana with Eriocaulon and 

 Utricularias cornuta, gibba and resupinata. At the water line are found 

 Populus deltoides, nowhere else seen, and seemingly dependent on water 

 contact for its seed germination, mixed with Salix Bebbiana and S. myrtil- 

 loides. These form simply a roio. Next landward is a belt of 2-3 feet of 

 Mola lanceolota, then comes a strip of Spirea Etomeutosa, rose and white 

 forms a rod wide, the outer margin gay with apius, and in late summer fairly 

 dotted with Gerardia purpura and G. aspera and heavy with the perfume 

 of Gyrostachys cernua. This belt is broken on Cable Lake by a gravel point 

 covered to the water with Cassia nictitans, elsewhere absent from the whole 

 region. This point also is clothed with Juniperus Virginiana, also an iso- 

 lated occurrence.
