The SENNINSOH, or Sweet Autumn Clematis, belongs to the buttercup family and ranges throughout most of Japan. It is a lianoid perrenial herb and its flowers become conspicuous much earlier here in Amami than in more northern parts of Japan. During the rainy season starting early May, the vines climb up other trees, densely blossoming white small flowers, which forms a striking contrast against an overcast sky of the moist season.

The YAMBARU-SENNINSOH, or Clematis mayeniana, ranges on Tanegashima, Yakushima and southward. The two species resemble each other very closely. Since I am not able to distinguish between the two well, the pictures shown here are not identified which is which.
