Recently a friend returning from Baja brought back some shots of a tuberous vine, Exogonium bracteatum. I have not found out a lot about it in the meanwhile other than where it is found, its family (Convolvulaceae) etc. and that someboby at Arizona State has been looking at it. I have not found a botanical description. Its bracts dominate the infloerscence and are amazing. Considering the climate where it grows, a tuberous plant is indeed a wonder as it sends its tendrils into tall bushes in their leafless state. Does Leo perhaps know more? When was it discovered and who found it? Thanks Andrew San Diego
