Cryptocentrum calcaratum (accession no. K13598). (A) Bicellular hairs of C. calcaratum comprising a basal cell and a longer, tapering terminal cell with rounded tip. Scale bar = 100 µm. (B) Pubescent, proximal part of cymbiform region of labellum with isodiametric, epidermal cells. Scale bar = 500 µm. (C) Increasingly pubescent region of labellum close to the origin of the spur. Note that isodiametric, epidermal cells are still present here. Scale bar = 500 µm. (D) Detail of trichomes from the proximal part of the cymbiform region of a labellum. Scale bar = 100 µm. (E) Pubescent, internal surface of a spur. Note the elongate epidermal cells. Scale bar = 500 µm. (F) Detail of the internal surface of a spur showing trichomes and elongate epidermal cells. Scale bar = 100 µm.
