inner bark of an orange color, and valuable in 

 tanning and dyeing. The wood is extensively 

 employed for timber and fuel, but is inferior to 

 the White Oak. 



Quercus coccinea, variety vulgaris (Fig. 213) 

 is probably the commonest form of the species, 

 especially in the Western States.' The leaves 

 are cut more than half-way to the midrib, 

 bright green and shining both sides, and with 

 long slender petioles. The fruit is somewhat 

 larger than in the preceding, but in tlie figure 

 is represented rather disproportionately large. 



[Fig. 213] 



Black Oak {Quercus coccinea, var. microcarpa.) 



This is a very common form, especially in 

 Northern Illinois. The leaves are unusually 

 large and finely lobed, the acorns small and 

 pointed, and the cup very shallow. 



Quercus coccinea, var. tinctoria (Fig. 211). 

 This is the form which has usually been called 

 Quercus tinctoria, Bart. The figure is from a 



Pennsylvania specimen, and is reduced in size 

 about one half. The leaves are less deeply lobed 

 than any of the others, with 'shorter petioles, 

 and generally with some rusty down along the 

 veins on tlie under side. The acorns are about 

 half an inch long. This variety is not, accord- 

 ing to our observation, common in the Western 

 States.

4th. The variety depressa, with leaves like 

 those of the variety microcarpa, but with much 

 larger and shorter acorns, the scales of the cup 

 loose at the border. It approaches Quercus 

 palustris, DuRoi. 



5th. Variety coronata, with obconic cup, the 

 border forming g, crown of loose scales. 



6th. Variety m<en«edja!, intermediate between 

 the varieties depressa and microcarpa. 



NOTES ON PLANTS COLLECTED NEAR CHICAGO. 



BY II. A. WAKNE, CHICAGO, ILLS, 



The summer months afford a rich harvest of 

 interesting species to the collector in Northern 

 Illinois ; for the region near the south shore of 

 Lake Michigan seems to combine, in a remark- 

 able degree, the distinctive plants of the prairie 

 with many that appear to belong more properly 

 to the States further north and east. 



As the season ijrogresses beyond the chances 

 of frost, the richer-hued plants hasten into bloom 

 in troops, ui^tU June and July are gay with 

 flowers. Conspicuous among these is the bril- 

 liant Scarlet Painted Cup, which Bryant has 

 celebrated in exquisite verse, and a bright yellow 

 variety of tlie same species (Castelleia coccinea). 



Space will allow me to give only a partial list 

 of our summer plants. The Perennial Lupin 

 \ {Lupinus perennis) finds a favorite habitat here, 

 and sometimes makes the space of an acre beau- 

 tiful with its sky-blue flowers. The Golden 

 Alkanet (Litliospermum canescens) delights in 

 the same locaUty, and a little later the showier 

 Lithospermums come into bloom, both L. hirtum 

 and L. lonyiflorwii, but the latter not common. 

 The Prinu'ose family is represented by the Shoo(> 

 ing Star {Dodecatheon Meadia). Its pretty 

 pink-purple flowers, with coquettishly reflexed 

 petals, are quite unique in aspect, and suggest 

 the favorite Cyclamen of the greenhouses. It 

 varies to pure white. 



An old Swedish botanist who had visited 

 Chiciigo, and was taken to one of our best wild 

 garden spots in June, exhibited all the enthusi- 

 asm of a child at the pleasant sight, and could
