Beach morning glory is an abundant tropical strand sp. The small colony recorded from Ninety Mile Beach almost certainly originated from seeds recently floating there. N.Z. plants are referable to subsp. brasiliensis (L.) Ooststr., the usual subsp. occurring in tropical regions. Like I. cairica it belongs to sect. Leiocaylx.
