Chrysosplenium macrostemon var. atrandrum
Chrysosplenium macrostemon var. atrandrum Saxifragaceae
They are perennial plant that grows at humid forest such as at rocky places along the mountain stream in mountain areas and (perennial plant takes several years to grow). The dark green leaves have grayish patterns. These patterns are like being covered with dust, and that is why they are named Chrysosplenium macrostemon var. atrandrum. The flowers are 3 to 4 mm in diameter and its characteristic is that 4 dark red flower-like calyxes rise perpendicularly. Inside of calyxes are stamens, and just below the yellow bract leaf spread (Houyou: a modified leaf or leaflike part just below flower stalk).
The number of stamen is four, the same with the one of Chrysosplenium grayanum. When the flowers wither, the flower stalk spread to four directions resulting in growing large several leaves. Though they are a mutation of Chrysosplenium macrostemon (as known as by Chrysosplenium macrostemon) and both grow at similar circumstances, the point to distinguish is Chrysosplenium macrostemon has yellow-green calyx and their stamen is yellow.
