Rubus corchorifolius is
a deciduous shrub inhabiting forest edges in mountainous regions,
giving various forms like standing, crawling, etc. New branches wear
dense velvety hairs; however, they disappear in a particular stage.
Leave are of alternate phyllotaxis, blades measure 4-10cm in length,
in the shape of a broad ovate, occasionally cleft in three, with
margins sharply serrated. White flowers, 1.5-2cm in diameter, bloom
facing downwards on short sprigs that emerged from the previous
year's branches. There exist dense velvety hairs on petioles and
sepals. Bloom time: April-May.
