Straussia sessilis O. Deg. & Hosaka , Bull. Torrey Bot. Club 67: 301. 1940.
Type information:
Holotype [BISH]. O. Degener and F.C. Salucop 11525. 24 October 1937. O`ahu: N of head of Makua Valley, in rain forest. Isotype(s) [BISH! [3], GH, MASS!, MO!, NY [mfc!], US, W].

Note: Non Psychotria sessilis Vellozo (1825) nec Müll. Arg. (1881). Sohmer's lectotypification (Lyonia 1: 166. 1977) is superfluous, as it is clear that the holotype was part of Degener's herbarium, on loan to BISH at the time of publication but later accessioned by BISH.
