The upper leaves are lanceolate or linear, the lower ones broader, and all slightly toothed. The flowers are protandrous, the outer stamens opening first, and turn- ing the pollen outwards. The stigma is, however, mature before the innermost stamens have shed their pollen. The insect visitors are not numerous. They comprise the hive bee and some species of Halictus, a few beetles, one or two Lepidoptera, and several species of flies. R. acris, repens, and bulbosus.—These species offer some very interesting problems. R. acris is erect and tall; R. repens, as the name denotes, is a creeping plant; while R. bulbosus has the stem thickened at the base into.

Moreover, it differs from the other two in that the sepals bend downwards in the middle—a character we have just noticed in R. sceleratus which recurs in R. hirsutus and some foreign species. R. acris is softly hairy, the hairs generally spreading, but deflexed on the lower parts of the stem, and appressed on the peduncles. In R. repens the hairs are longer and looser. R. bulbosus is generally somewhat hairier. In all three the leaves are much divided, but in R. acris the divisions are finer. In R. acris the outline is rounded, in R. repens it is ovate; the leaves of R. bulbosus resemble those of R. acris, but are broader. The peduncle is glabrous and furrowed in R. bulbosus, hairy and furrowed in R. repens, hairy but not furrowed in R. acris. The carpels are glabrous in R. acris and.
