THE AMERICAN 



ernatum from this region. "We may add to our 

 list also tlie following, collected May 1st at 

 Graceland suburb, a few miles north of the city : 

 Of Violets, four species, viz., Viola cucullata, 

 V. blanda, V. pedata, and V. sagittata ; Marsh 

 Marigold (Gattha palustris), Ranunvulm faaci- 

 cuiaris, the Wood Anemone (A. nemorosa), 

 Phlox bifida, Antennaria plantagini folia, Ara- 

 bis lyrata, Cardamine rJiomboidea, var. purpu- 

 rea, and Trillium cernuum. A weeli later were 

 found Uvularia grandifiora, and Polemonium 

 reptans; and at Hyde Park suburb, the Ameri- 

 can Cowslip (Dodecatheon meadia), the Hoary 

 Stonc-secd (Lithospervium canescens) , the Lark- 

 spur Violet, {Viola delphini folia) , the Lance- 

 leaved Violet (F. lanceolata), the wild Lupine 

 {Lupiinus jjerennis), "Wood Rue {Thalictrum 

 dioicum), and Yellow Star-grass {llypoxis 

 erecta) . 



Along the lake shore here the Bcarberry 

 (Arctostaphylos uva-ursi) was beginning to 

 bloom, but to our disgust was speedily scorched 

 and blackened by a fire kindled on the shore by 

 some vandals. 



Valeriana eduKs was found in an old fenced 

 field hereabout in the greatest abundance, the 

 plants apparently of great age, forming solid 

 woody clumps, half a foot in diameter. The 

 great abnndance of this plant here, though 

 sparingly found elsewhere, almost seriously 

 suggested the notion of cultivation by the In- 

 dians ill time past. The white Lady's Slipper 

 {Gyiyripedium candidum) seems to find a con- 

 genial home in association with this plant, for 

 a week later over a hundred specimens were 

 collected in this field. Like its companion, it 

 is not common, but occurs abundantly in a few 

 places. 



A trip to the rich wooded district along the 

 north branch of Chicago river about May 15th 

 was quite fruitful, yielding the following species : 

 liammculus abortivus, Viola pubescens (a form 

 with remarkably large and beautiful flowers), 

 Dentaria laciniata, the Creeping Crow-foot 

 {Ranunculus repiens), wild Turnip {Arismma 

 triphyllum) , Trillium recur vatum,Jih\e Cohosh 

 {Caulophyllum thalictr aides), Hed Cohosh (Ac- 

 tea spicata), Feverwort (Triosteum perfolia- 

 tum), wild Geranium (Geranium maculatum), 

 wild Gooseberry (Bibes hirtellum), wild Black 

 Currant (Bibes floridum), May Apple (Podo- 

 phyllum pellahim) , Fi\e-&ngev (Poteniilla Gan- 

 adensis), wild Ginger (Asarum Canadensis), 

 Scarlet Thoru (Grategus coccinea), Black Thorn 

 (C. tomentosa), wild Crab Apple (Pyrus coro- 

 naria), Shad-bush (Amelanchier Ganadensis), 

 wild PluDi (Prunus Americana), wild Black 



Cherry (P. serotina), Bur Oak (Quercus mac- 

 rocarpa). White Oak (Q. alba), Red Oak (Q. 

 tinctoria). Red Elm (JJlmus fulva, in fruit). 

 Blueberry ( Vaccinium Pennsylvanicum) ,'B\ack 

 Huckleberry (Gaylussacia j-esmosa), with that 

 little oddity, the False Mermaid (Floerka pros- 

 erpinacoides) , in great abundance. 



The procession of the flowers from this date 

 to the close of May this season was astonish- 

 ingly rapid, fully ten days in advance of the 

 usual time. At Calumet, fonrlcen miles from 

 the city, we found the delicate Bluets (Housto- 

 nia cerulea) and Sweet Fern (Comptonia as- 

 plenifolia). This peculiar locnlity affords rari- 

 ties throughout the season; while Glencoe, a 

 somewhat distant collecting ground, yields us 

 now the Buffalo-bush (Shepherdia Canadensis). 

 Along the lake shore we find on sandy hillocks 

 two species of Prunus in bloom, the Choke 

 Cherry (P. Virginiana), and the Sand Cherry 

 (P. pumila). The shrubs of the latter are ap- 

 parently very old, and of remarkable size for 

 the species, some being fvora three io four feet 

 in height. The Dwarf Birch (Betula pumila), 

 is now to be found sparingly in the region of 

 Rose Hill suburbs. 



An excursion to Hyde Park (May 29th) af- 

 forded, among other things. Golden Alexanders 

 (Zizia integerrima) and Thaspium aureum, a 

 handsome wild Coreopsis (Coreopsis lanceo- 

 lata), the large Yellow Lady's Slipper (Gypri- 

 pedium pubescens), Blue-flag (Iris versicolor), 

 Cynthia Virginica, the Painted Cup (Gastilleia 

 coccinea), yellow and scarlet varieties, Spider- 

 lily (Tradescantia Virginica), Large Alum-root 

 (Heuchera hispida). Marsh Pea (Lathyrus pa- 

 lustris). Beach Pea (L. maritimus), and wild 

 Columbine (Aquilegia Ganadensis). The beau- 

 tiful little Collinsia verna has been collected at 

 the Des Plaines river. 



In several excursions during the latter part 

 of May the following were collected : In fruit, 

 the Witch Hazel (Ilamamelis Virginica), un- 

 expectedly found near the cit)^ In flower, at 

 the same locality, the High Cranberry-bush 

 (Vibi(,ruum opulus), supposed to be the original 

 of the Snow-ball of the gardens, the Sweet 

 Viburnum (V. lentago) , and wild Sarsaparilla 

 (Arabia nudicaulis) . To this list we will only 

 add the wild Indigo plant (Baptisia leuco- 

 plien), wild Hyacinth (S'cilla Fraseri), Water 

 Crow-foot (Banunculus multifidus), Seneca 

 Snake-root (Poly gala Senega), Maple-leaved 

 Viburnum (V. aceri folium) , Small-flowered 

 Honey-suckle (Lonicera parviflora), and the 

 Small-flowered Lady's Slipper (Cypripediv.m 

 parviflorum) ,
