distribution, being also a native of Pugef s Sound, 

 Japan, Australia and Eastern India. 



Petalostemon Candidas and P. violuceus, dis- 

 tinctive prairie plants, and called Prairie Clover, 

 are both common here. Among a number of 

 leguminous plants I may also enumerate Astra- 

 galus Canadensis, a vigorous, tall plant witli 

 cream-colored flowers, the Ground Nut (Apios 

 tuberosa) a handsome vine of strong growth, 

 with violet-scented flowers of chocolate color, 

 Lathyrus pahistris and L. mariiimus, the Beach 

 Pea, us much at home here as on the sea shore, 

 associated also vi\i\\ Phaseolus diversmfolius here 

 as along the Atlantic — both confined to tlie im- 

 mediate neighboihood of the Lake, and delight- 

 ing in pure sand. The so-called Lead Plant 

 (Amorpha canesceyis), named from a miner's 

 whim, is partial to the sandy Lake region also. 

 Its violet flowers are quite singular, consisting 

 of one single petal wrapped about the stamens, 

 and quite often puzzle the young botanist, 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 po.»is 

 asinarum to the youthful plant-analyzer is the 

 Rattlesnake Master {Eryngium yuccmfoliani), 

 quite common here, which few would take at 

 sight to be related to tlie members of the Pai sley 

 and Carrot family. 



Peculiar to the Lake shore, also, and almost 

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

 kile Americana) , with flowers and pods much 

 like those of its cousin tlie Radish, but otherwise 

 of very different aspect. It is generally found 

 with Euphorbia polygonifolia, a distinctive 

 j)laut of the Great Lakes, and Corispermum 

 hyssopifoUum, a plant adventive from the North- 

 west, but thoroughly established here. Its 

 general appearance somewhat suggests Salsola 

 of the Atlantic coast. Potentilla amerina, the 

 Silver Weed, also claims its place along the 

 Lake shore with these last named plants, tliougli 

 higher up on the beach, where it throws out long 

 runners, bright with golden flowers and silver- 

 lined leaves. Its taller relative, Potentilla fruti- 

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

 cultivation for its beauty. Potentilla palustris, 

 the Marsh Five-flnger, is found in wot places 

 here and there also. 



A list of the shore plants is very incomplete 

 without a brief mention of the more striking 

 grasses tliat attract the eye: these are Calama- 

 grostis arenaria, the Sea-sand Reed, C. longi- 

 foliu, Sorghum nutans, Sporobolus heterolepis, 

 Stipa spartea, the Porcupine Grass, Andropogon 

 furcatus and A. scoparius, Elymus Canadensis, 

 "Wild Rye," Spartina cynosuroides, Fresh 



Water Cord Grass, and Sordeum 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 Pine Station, only twenty 

 miles distant from Chicago, we flud ourselves in 

 the midst of evergreen woods, with scarcely a 

 deciduous tree to be seen. Here were the White 

 Pine {Pinus strobus), and Pinus Banksiana, the 

 Gray Scrub Pine, with the common Juniper 

 (Juniperus communis \Si\- . alpinus), frosty with 

 the white bloom of its ahundaut 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 Cranberry ( Vaccinum macrocarpon) ; my 

 list includes also the Dwarf Sumach {Rhus co- 

 pullina), the Black Alder {Ilex verticilla), the 

 Sour Gum Tree (Nyssa multiflora), the Leather- 

 leaf (Cassandra calyculata), the pleasant flavored 

 Wintergreen (Oaultheria pi-ocumbens), Pyrola 

 rotundifolia and Pyrola secunda. Two species 

 of the interesting Sun Dew family — Drosera ro- 

 tundifolia and longifolia — abounded, Melam- 

 pyrum Americanum, oddly termed Cow AVheat, 

 and the Sassafras tree. The delicate little blue 

 Iloustonia cerulea ttlled the spaces among the 

 grass, with occasional plants of our yellow 

 flowering flax, Linum Virginianum. In the 

 wet grounds we found Utricularia cornuta 

 and Utriaclaria vulgaris, the horned and the 

 greatei- Bladder-wort. Pogonia ophioglossoides 

 in profuse numbers scented the air with its rich 

 fragrance, vieing with its beautiful but scentless 

 relative Calopogon jyulchella, of which I never 

 met equally fine specimens; the flower-stalks 

 were e.xceedingly 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, Habenaria ciliaris, with bright 

 orange flowers, was abundant. Talinum tereti- 

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

 far distant, Hudsonia tomentosa and Campanula 

 rotundifolia var. linifolia. The beautiful Moc-
