distribution, being also a native of Pugefs Sound, 

 Japan, Australia and Eastern India. 



Petalostemon Candidas and P. violnceus, dis- 

 tinctive prairie plants, and called Prairie Clover, 

 are both common hero. Ainong a number of 

 leguminous plants I may also enumerate Astra- 

 galus Canadensis, a vigorous, tall plant with 

 cream-colored flowers, the (Jround Nut (Apios 

 tuberosa) a handsome vine of strong growth, 

 with violet-scented flowers of chocolate color, 

 Lathyrus palustris and L. marilimus, the Beach 

 Pea, as mucli at home here as on the sea shore, 

 associated also with Phaseoliis diversaif alius here 

 as along the Atlantic — both confined to the im- 

 mediate neighborhood of the Lake, and delight- 

 ing in pure sand. The so-called Lead Plant 

 {Amorpha canescens), named from a miner's 

 whim, is partial to the sandy Lake region also. 

 Its violet flowers are (piite singular, consisting 

 of one single petal wrapped about the stamens, 

 and ((uite often puzzle the young bcffanist, who 

 sees little of the pea family in the aspect of such 

 a flower, the standard being only left, the other 

 petals absent. But quite as much of a poyis 

 asinaruin to the youthful plant-analyzer is the 

 Rattlesnake Master (^Erynyium yuccmfolium), 

 quite common here, which few would take at 

 sight to be related to the members of the Parsley 

 and Carrot family. 



Peculiar to the Lake shore, also, and almost 

 within reach of the spray, is the Sea Rocket (C'«- 

 kile Americana), with flowers and pods much 

 like those of its cousin the Radish, but otherwise 

 of very diflerent aspect. It is generally found 

 with Euphorbia polyyrmifolia, a distinctive 

 plant of the Great Lakes, and Corispermum 

 hyssopifolium, a plant ad ventive from the North- 

 west, but thoroughly established hci'e. Its 

 general appe.Trancc somewhat suggests Salsola 

 of the Atlantic coast. Potentilla anserina, the 

 Silver AVeed, also claims its place along the 

 Lake shore with these last named plants, though 

 higher up on the beach, where it throws out long 

 runners, bright with gohlen flowers and silver- 

 lined leaves. Its taller relative, Potentilla fruli- 

 cosa, grows with it in places, a plant worthy of 

 cultivation for Its beauty. Potentilla palustris, 

 the Marsh Five-finger, is found in wet places 

 here and there also. 



A list of the shore plants is very incomplete 

 without a brief mention of the more striking 

 grasses that attract the eye : these are Calama- 

 f/7-oslis arenaria, the Sea-sand Reed, C. lonyi- 

 folia, Sorghum nutans, Sperobolus heterolepis, 

 Slipa spartea, the Porcupine Grass, Andropogon 

 furcalus and A. scoparius, Elymus Canadensis, 

 "Wild Rye," Spartina cynosuroides, Fresh 



AVater Cord Grass, and Hordcum jubatum, the 

 Squirrel-tail Grass, sometimes cultivated for 

 ornament elsewhere. 



An hour's ride in the cars takes us into the 

 county of Lake, in our neighboring State of Indi- 

 ana. Here the aspect of the flora seems entirely 

 changed. Coming to I'iue Station, only twenty 

 miles distant from Chicago, we And ourselves in 

 the midst of evergreen woods, with scarcely a 

 deciduous tree to be .seen. Here were the White 

 Pine (^Pinus slrobus), and I'inus lianksiana, the 

 Gray Scrub Pine, with the common Juniper 

 (Juniperus communis var. alpinus), frosty with 

 the white bloom of its ahundant fruit. The 

 herbaceous plants associated with this evergreen 

 growth are in strong contrast with the prairie 

 vegetation immediately about Chicago. 



The narrowness of this belt of pine woods is 

 singular. Passing on to the shore of Lake Michi- 

 gan we find the evergreens disappearing, while 

 the oaks and poplars reappear. Soon only an 

 occasional pine tree can be seen, until at Miller's 

 Station, nine miles further at the Lake shore, I 

 do not remember to have seen an evergreen. 

 But the herbaceous flora here strongly suggests 

 Michigan and the Eastern States. We find the 

 Huckleberry in profusion, and in wet places the 

 large Craidjerry ( Vaccinum macrocarpon) ; my 

 list includes also the Dwarf Sumach {Rhus co- 

 pallina), the Black Alder (Ilex verticilla), the 

 Sour Gum Tree (Jfyssa miUtiflora) , the Leather- 

 leaf (C'aAwixrfrffl calyculata), the pleasant flavored 

 Wintergreen (Gaidtheria j^rocumbens) , Pyrola 

 rotundifolia and Pyrola secunda. Two species 

 of the interesting Sun Dew family — Drosera ro- 

 tundifolia and longifolia — aboundc<l, Melam- 

 pyrum Americanum, oddly termed Cow AVIicat, 

 and the Sassafras tree. The delicate little blue 

 lloustonia cerulea filled the spaces among (he 

 grass, with occasional ])lants of our yellow 

 flowering fla.x, Linum Virginianum. In the 

 wet grounds we found Utricularia cormita 

 and Ulriaclaria vulgaris, the horned and the 

 greater Bladder-wort. Pogonia opliiaglossoides 

 in profuse numbers scented the air with its rich 

 fragrance, vicing with its beautiful but scentless 

 relative Calopogon pulchella, of which I never 

 met equally fine specimens; the flower-stalks 

 were exceedingly vigorous, with ten or twelve 

 blossoms on some, the whole plant exceeding 18 

 inches in height. One specimen of Liparis 

 Loesellii was found. A fortnight later the hand- 

 some Orchid, Ilabcnaria ciliaris, with bright 

 orange flowers, was abundant. Talinum tereti- 

 folium was also met witti, and, at a locality not 

 far distant, Iludsonia tomentosa and Campanula 

 rotundifolia var. lin^'olia. The beautiful Moc-
