Kerwileton 1950 Journal 34 Nov. 8 Villavieja, 1400ft., Huila, Colombia, S.A. P.M., Paulino and I made another trip to the chapel, collecting nothing there. The plant which I have seen in green, apparently vigorous, growth on the high plate near Camp Cerbetara (Adipora bicaularis?) also grows around the cemetery in abundance. Paulino and Perico say it reaches a height of about 3ft. On this night we observed the striking posture of its leaves at night: In the day time the plant appears (roughly) like this: At night: The leaflets of opposite sides are closely appressed, and the three pairs folded as closely as possible into one unit. The terminal pair inside, the bottom-most pair outside. The striking thing to me, as best I can recall it, is that all surfaces presented outward in the folded position are those which form the undersides in the expanded (Day) position (necessitating a full 180° twist of the leaflet petioles?)
