Abstract

GYELTSHEN, Nima; TOBGYEL, Kezang  and  DALSTROM, Stig. A New and striking spathoglottis (Orchidaceae: Collabiinae), honoring her majesty the queen of bhutan. Lankesteriana [online]. 2017, vol.17, n.3, pp.395-401. ISSN 1409-3871.  http://dx.doi.org/10.15517/lank.v17i3.31575.

A new, attractive and morphologically unique species of Spathoglottis is described, illustrated and compared with the most similar species. The new species is currently only known from two localities in southeastern Bhutan and differs distinctly from its closest relative, Spathoglottis hardingiana, by the glabrous pedicels, forward-curved acuminate apices of the petals, a yellow hypochile of the lip, two pairs of unequal callus “horns” and swellings, and a spirally coiled epichile of the lip, versus a densely pubescent inflorescence and pedicels, a pale purple hypochile, a single pair of erect and clavate, or“bubble-shaped”, callus swellings, and a projecting and narrowly triangular epichile of the lip for S. hardingiana.

Keywords : Orchidaceae; Collabiinae; new species; Spathoglottis; Bhutan.
