l. D. rotundifolia, L. (Fig. 1, pl. 58.) RouNnp-LEAVED SUNDEW. 
Plants 4 to 10 in. high. Leaves nearly orbicular, depressed at center, 
which is occupied by a viscid exudation, Leaf-stem and edges of leaves 
thick set with glandular hairs. Flowers 4 to 12 ona slender scape with 
quite short flower stems, white, about 1/6 in. broad. In swamps, through- 
out our area. July-Aug. 
2. D. intermedia, Hayne. (Fig. 2, pl. 58.) SPATULATE-LEAVED SUN- 
DEW. Similar to No. I, but leaves are elongated, spatulate, rounded at 
apex and narrowed at base. The plant is usually smaller than No. 1 
and the color of leaves darker. Less common than No. 1, growing in 
similar situations. July-August. 
3. D. longifolia, L. (Fig. 3, pl. 58.) OBLoNG-LEAVED SUNDEW. Re- 
sembles No. 2, but leaves are still more elongated, and while in Nos. 
1 and 2 the leaves lie flat upon the surrounding moss or mud, in this 
species the leaves are more nearly erect. Whole plant more delicate than 
either of the preceding species. In bogs, less common than No. 1, bloom- 
ing at about the same time.

Order VI—ROSALES. Order of the Rose Alliance 
This large order unites within itself plants of widely divergent 
habits and appearance. They include trees, shrubs and _ herbs. 
Mostly they are land plants, but a few find their homes in swamps 
and one, in our region, Podostemon, is an entirely submersed 
aquatic. 
The characteristics which join this greatly varied group into 
an order are: 
Ist. The presence of both sepals and petals, the latter of which 
are distinct, that is, they are not united by their edges as they 
are in such flowers as the blue-bell or morning glory, but are 
separate as in the single rose. The sepals of the calyx are to 
some extent confluent, but always show at least a partial division. 
To this general law of characterization there are exceptions:
