I have to agree that it looks like it very well could be this plant. You may want to check the leaf characteristics and look for lenticles to make sure. Your picture doesn't show the leaf base as being oblique but that could be a matter of photographic angle.
Pterospermum reticulatum (MALVACEAE, Sterculioideae) ... note the correct spelling of the genus; the former Sterculiaceae are now a subfamily within the family MALVACEAE >>> see APweb at http://www.mobot.org/MOBOT/research/APweb/
