The Rhamnaceae of the Kimberley Region of Western Australia
RYE, B.L.
Six native species of Rhamnaceae, all in different genera, are known from the Northern Botanical Province of Western Australia. This province is equivalent to the Kimberley Region as defined in "Flora of the Kimberley Region", in which five of the Rhamnaceae species are described and illustrated (Wheeler 1992). Since publication of the Kimberley flora, a further species and genus, Colubrina asiatica, has been discovered at Koolama Bay in the far north of the Kimberley, and there has been an alteration of the specific name used for the Alphitonia species in the region. In addition, unpublished work on generic boundaries in the Rhamnaceae suggests that the species currently known as Cryptandra intratropica should be placed in a new genus (K. Thiele pers. comm.).
