In the remaining families the corolla is gamopetalous, that is, the petals are coherent into a more or less well-formed tube, though they may be free at the end. For this reason they are known as the svmpetalce. Topic VIII: Dicotyledons with united petals, flower parts in five whorls. BICORNES. 539. The pyrola family (pyrolacese).—The shin-leaf or wintergreen (Py- rola elliptica), not the aromatic wintergreen, is figured at 377. The oval or elliptical leaves are clustered at the base.

The pyrola family (pyrolacese).—The shin-leaf or wintergreen (Py- rola elliptica), not the aromatic wintergreen, is figured at 377. The oval or elliptical leaves are clustered at the base. The flower scape is 15-30 cm high and bears a raceme at the summit. The flowers hang singly from the axils of colorless bracts. The floral formula is as follows : Ca5,Co5,Alo,G5. The Indian- pipe (monotropa) is also a member of the pyrola family. 540. Lesson XVI. The whortle- berry family (vacciniaceBe).—The common whortleberry, or huckleberry (Gaylussacia resinosa), flowers in May and June. The shrubs are from 30COT to 1 meter (1-3 feet) high, and are much branched. The leaves are ovate, and when young are more or less clammy from numerous resinous dots, from which the plant gets its specific name (resinosa). The flowers are borne on separate shoots from 2S3.
