Type.

Java. K. Goebel (syntype: G [G00115804!]).

Remarks.

The species was described from Java based on K. Goebel specimen ( Schiffner 1893) and is mostly Malesian-Papuasian in distribution, probably reaching westward to northern Thailand (if the report by Kitagawa 1988 is correct) and spreading eastward to Samoa. We did not see the specimens of this species from northern Indochina. However, Calypogeia lunata   is quite abundant, morphologically malleable and provides some modifications superficially resembling C. goebelii   in northern Vietnam, although never having such distinctly lobed leaves as occur in ‘true’ C. goebelii   , nor narrow underleaves (1.5-2.0 as wide as the stem, as commonly occurs in C. goebelii   ). Moreover, Kitagawa (1988) did not observe blue oil bodies in his specimens, and he provides a yellowish color for the plants, whereas the plants that have blue oil bodies commonly develop greenish-whitish to grayish pigmentation in the herbarium. Thus, it is an open question whether the specimens named C. goebelii   by Kitagawa truly even belong to the blue-oil-bodied Calypogeia   complex. The type of C. goebelii   is actually similar to that of C. tosana   in general outlook, and the differentiation from the latter in the absence of oil bodies is quite troublesome. Therefore, we are unable to confirm or reject this species from the northern Indochinese flora, although we doubt it.

The description based on the isotype is as follows: plants brownish, pellucid, glistening, 1.5-2.5 mm wide, 5-8 cm long; stem 150-200 µm wide, sparsely ventrally branched; rhizoids brownish, common to numerous, obliquely to erect spreading fascicles; leaves contiguous to somewhat distant, slightly convex, decurrent for 1-2 stem widths, 750-1250 × 575-1050 µm, divided by U-shaped sinus into two acute lobes; underleaves, obliquely spreading, 1.5-2.5 as wide as stem, bisbifid, the undivided portion in the underleaf middle 2 cells high, arcuately inserted, not or barely decurrent; midleaf cells thin-walled, trigones very small, concave, 37.5-55.0 × 25.0-37.5 µm.
