poorest soil and the smallest number of striking plants, and yet a few are 

 most noteworthy. The hickory mentioned is Hicoria microcarpa of Brit- 

 ton's flora. Prof. Sargent practically ignores this species, passing it off 

 apparently as a variety of H. glabra. It is very distinct and characteristic, 

 beautiful in form, very fragrant of fruit, which is sweet but perfectly un- 

 satisfactory by reason of the difficulty of extraction. Liriodendron is found 

 occasionally, and Sassafras has become in old vacated fields and along fences 

 a veritable weed. The most striking herbaceous plant is Frosera. a photo- 

 graph of Avhich is shown. On a gravelly ridge one mile north of Magician, 

 blooming ])lants were found by the hundred in 1905. Not one was found in 

 1906, and only half a dozen young plants. The plant has an enormous root 

 and it certainly does not bloom imtil the third year, and perhaps later. 



Several root parasites are conunon and interesting. Conopholis grows 

 in clusters, invariably beneath oak trees, and is an oddity. Monotropa, 

 both Avhite and pink, is very abundant, blooming from July to September. 

 Corallorhiza multiflora is very common in all oak timber. Several Dasy- 

 stomas, by some considered not parasitic, are most conspicuous additions. 

 Smilax rotundifolia forms many a forbirlding clump, and Meibomia bracteosa 

 is at home. A very rare orchid, Triphora. has been found in two spots, grow- 

 ing in thick oak leaf mulch. Another rarity, or at least a jilant most diffi- 

 cult of discovery, is Aristolochia serpentaria, found only in oak woods. of 

 Magician Lake and bearing only cleistogamous flowers. A sunny slope in 

 this same wood yields Drabaverna. Mesadenia atriplic folia, three Lactucas, 

 several Hieraciv.ms and Solidago neglecta are the more interesting composites. 

 Many leguminous plants, notably Lespedezas, Cracca, Mcia cardiniana and 

 Lupinus freciuent barren open knolls. One single location has been found 

 for Kouhuistera, near Crooked Lake. • 



The beech and maple land could hardly support a more different growth 

 if removed geographically far distant. It may be explained that while this 

 forest runs across the northwest part of the survey at a distance of only 

 five miles from my cottage base, I never really entered the area until 1906, 

 and my surprise was boundless. Huge trees of beech, hard, maple, basswood, 

 and occasional hackberry, coffee beans, black cherry and red elm, Avere con- 

 trasting enough with my oak groves, but when my looks came down to a low- 

 er stratum of asimina, fairly dark with bloom, Sambucus])ubeus, Enonymus 

 atropurpurus and Xanthoxylum, it was interesting, and when I found the 

 earth clothed with such (to me) almost unknown species as Erythronium 

 Americanum (out of bloom), Trillium declinatum (see revision of this genus), 

 Galeaorchis spectabilis, Aplectrum hyemale by dozens and fifties. But 

 pause here to note that the yellow-green form of Prof. Underwood's N. Y. 

 station is the only form found here. Asarum reflexum, actasa alba, Caul- 

 ophyllum are common but not peculiar. But look at that great mass of 

 leaves with gold spots here and there. Surely Stylophorunl en masse, my 

 first sight of the plant, and everywhere the leaves of BicucuUa Canadensis. 

 Digging into the leaf mold the yellow "cones" are sown broadcast, so that 

 there is one or more for eA'ery six inches. Beautiful to behold are the myriads 

 of Viola Canadensis, never seen before except in Canada. Plants. are often 

 two feet in height. Sanguinaria was evidently a common flower in March 

 and April. Geranium Robertianum is as common as Viola, and fairly 

 saturates the air with its peculiar heavy odor. One Panax quinquefolium 

 graced the scene. Erigenia in fruit was found in a few spots. Twice be- 

 fore I met this species, once at Naperville and once at Champaign, 111. Great 

 masses of Hydrophyllum Canadense in leaf with small flower buds told of
