S. ramalinoides is a very distinctive, elongate, finger-like species well separated from other New Zealand species. It occurs as an epiphyte of tree trunks amongst mosses in humid, subalpine forest habitats in northern North I. Although closely similar to the type from Patagonia, the New Zealand specimens occupy a habitat markedly different from that of the type locality. The possibility exists that these North I., plants may be specifically distinct.
