Abstract

Crassula nutans var. minus (Crassulaceae) a new trans-Tasman natural weed arrival to northern New Zealand.

Abstract

Crassula natans var. minus (Crassulaceae) is recorded for the first time from New Zealand, in the northern North Island at Lake Waiporohita, Karikari Peninsula. Native to southern Africa, this Crassula was previously known from Australasia only as a naturalized plant of Australia. Its discovery in the shoreline turf communities at Lake Waiporohita in mid November 2010 is regarded as a recent, natural dispersal event from Australia. Although Crassula natans var. minus has almost certainly naturally dispersed to New Zealand from Australia, it is regarded as naturalized to New Zealand rather than indigenous. A description of Crassula natans var. minus based on New Zealand specimens is provided.
