Comparison of two ecotypes of Kamarere: E. deglupta var. deglupta left and E. deglupta var. schlechteri right. The drawings on the left are typical of the New Britain, Indonesian Islands and Mindanao localities while those on the right are typical of localities on mainland PNG and in Papua and West Papua Indonesia (except possibly Vogelkop peninsula for which there are too little data to determine). a. Terminal, flowering branchlets; b. Green capsules, side view; c. Green capsules, end view; d. Longitudinal sections of flowers following anthesis; e. Inner calyptra; f. Transverse sections of ovaries; g. End views of mature fruits with four open valves. (Drawings by N Howcroft, Bulolo, 1973.)
