Sarcochilus is a well known and widely cultivated genus, at least as far as its Australian members are concerned. The New Guinea species of Sarcochilus are rather different from the Australian ones, not so much in the structure of the flowers as in the habit of the robust, long-stemmed plants with very short, one-flowered inflorescences. They were recently separated into the new genus Monanthochilus, which we have not adopted here, since we believe that the whole Sarcochilus alliance is badly in need of a careful phylogenetic analysis.
