Flora of Peoria. 31 
One of the peculiarities of our flora is the almost entire absence of the 
Conifers and Ericacez, there being but one species of the former, and it rare, 
and but three of the latter; the little, insignificent Monitropa uniflora, rare, 
the Vaccinnium vacillans found in but one circumscribed place and the 
Arctostaphylos Uva-ursi found in but one other place. 
The Euphorbiaccez is represented by two genera, one species of Acalypha, 
the A. Virginica common; and eight species of Euphorbia, viz; E. humistrata, 
rare, E. maculata, very common, E. hyperisifolia, common, E. dentata, com- 
mon, E. heterophylla, not rare, E. corollata, very common, E. obtusata, rare, 
and E. commutata, rare. There are two marked varieties of E. dentata, the 
typical form growing on rich ground, aid a low widely branching variety 
growing on dry gravely knolls with the lower branches as long or longer than 
the upright stem, leaves slender pointed, the whole aspect differing greatly 
from the typical form. No essential differences appearing between the two 
forms I planted the seeds of each side by side on moist rich soil, and when 
they grew could not tell the one from the other, the variety developed into 
the typical form. 
The Chenopodiums and Amarantus are abundant. They are all supposed 
to have been introduced. As rats follow civilization so do these homely 
weeds. As rats multiply and grow fat in the midst of plenty, so in this rich: 
soil these weeds grow rank and abundant. 
The Polygonacez order is represented by two genera, the Polygonum and the 
Rumex. There are eleven indigenous species of Polygonum, viz: P. amphibi- 
um, P. incarnatum, P. Pennsylvanicum, P. acre, P. hydropiperoides, P. avicu- 
lare, P. ramosissimum, P. Virginicum, P. sagitatum, P. tenue and P. dumeto- 
rum, and three introduced, P. persicaria, P. hydropiper and P. convulvulus. 
There are three indigenous species of Rumex: R. verticilatus, R. Britannica 
and R. hydrolapathum, and four introduced, R. obtusifolius, R. crispus, R. 
sanguineus and R. acetosella. 
Of the Scrofulariaceze orders we have indigenous the Scrofularia nodosa, 
Chelona glabra, Penstemon pubescens, Mimules ringens and M. Jamesii, Con- 
obia multifiida, Gratiola Virginiana, Ilysanthes gratioloides, Veronica Virgin- 
ica, V. anagallis, V. scutellata, Gerardia grandiflora, G. purpurea, G. tenui- 
folia and G. auriculata, Castillecia coccinea and Pedicularis Canadensis and P. 
lanceolata. Introduced Verbascum thapsus and V. blattaria, and Linaria 
vulgaris, Veronica arvensis. 
The Verbenacez is represented by the Verbena hastata, V. urticifolia, V. 
stricta, V. bracteosa, and a hybrid between the V. stricta and V. bracteosa, 
the Lippia lanceolata and Phryma leptostachya. 
The Borigenacz is rather a conspicuous order and is represented by the 
following indigenous species: Onosmodium molle, Lithospermum latifolium, 
L. hirtum, L. canescens and L. angustifolium, Mertensia Virginica, abundant, 
and Cynoglossum Morisoni. Introduced, Echium vulgare (?), Echino-spermum 
lapula and Cynoglossum officinale. 
The Asclepidacie order, is also worthy of notice. It is represented by the 
Asclepias cornuti, A. Sullivantii, A. phytolacoides, A. purpurascens, A. quad- 
rifolia, A. obtusifolia, A. Meadii, A. incarnata, A. tuberosa and A. verticillata 
Acerates viridiflora and A. longifolia. 
The Liliaceze is reasonably well represented. The Polygonatum biflorum 
and P. gigantium are common in our woods. The Smilacinia racemosa is also 
common. The S. stellata is found but is rare. The Scilla Fraseri formerly 
common is now rare. The Allium tricoccum and A. Canadensis are not rare. 
The Lilium Philidelphicum was formerly common on the prairies but is now 
rare. The L. superbum was formerly common in low, rich ground in the 
border of the woods, but is now almost extinct. 
The Nymphe tuberosa is common on the borders of the lake and in the
