Schroter states that there are male flowers .is well as the markedly protan- drous hermaphrodite ones. The two kinds are usually associated oil the same stocks, but a few plants are purely male. Kerner describes the umbels as possessing an intermediate zone ol' pseudo-hermaphrodite male flowers. Visitors.—Herm. Muller observed 5 beetles, 32 Diptera, 5 Hymenoptera, and 9 Lepidoptera in the Alps. 349. Pachypleurum Ledeb. 1143. P. alpinum Ledeb.—Ekstam describes the flowers of this species in Nova Zemlia as being markedly protandrous, sometimes protogynous-homogamous; their odour resembles that of elder, and their diameter is i-5-2 mm.

The small flowers (only about 2 mm. in diameter) possess yellowish- white petals, which are permanently involute. The stamens, that also are at first incurved, diverge as usual during dehiscence,
