FIGURE 2 in Taxonomy, evolution and phylogeography of the genus Helonias (Melanthiaceae) revisited
FIGURE 2. Diagram of phenology of rosette leaves and flowering stems (scapes) in Helonias. Phenological transition of rosette leaves (L) and flowering stem (F) in their lifetime (from bud formation to death) is schematized. Approximate magnitude of growth rate of two organs is expressed by line or shape of ellipse or lance (expanded portion). State of organs showing static, increasing or decreasing growth rate is represented respectively by line, or by expanding or narrowing (closing) portion of an ellipse or lance. Broken line represents period during which older leaves die, although their death is usually concentrated in growing season (April to July or August). In H. bullata, for example, leaf bud (see L-row) is initially formed in summer of year 0, it stays dormant until coming spring, and then develops rapidly in spring to summer (expanded open portion) of year 1. Mature leaves wither in growing season of following year (broken line in year 2). Flower bud of H. bullata (see F-row) is initially formed in fresh rosette (in L-row) in summer of year 1; like leaf bud it stays dormant until next spring, and then develops rapidly in spring (expanded shaded portion) of year 2. Flowering stem dies around summer of same year (closing shaded portion). Leaf bud (see L-row) of H. kawanoi, H. leucantha or H. umbellata after formed soon starts to sprout in late summer onwards (of year 0), although its growth appears more or less suppressed in subsequent cooler seasons (*). Phenological progression of flowering stem of H. kawanoi (F-row) tends to be lagged (**) when cultivated under lower temperature (in Tokyo) than in natural habitats.
