discovered, and though they were lelegated to their true 

 order, their identity with Nees and Meyen's imperfect speci- 

 men was not at first recognized. Ultimately, however, this 

 was established by Rolfe, who also showed that Acoridium was 

 identical with Bentham's genus Platyclinis. But inasmuch as 

 the former name had precedence over the latter by more than 

 40 years, PJatycIinis became reduced to a synonym of Acorid- 

 ium. About 1907 J. J. Smith reconstructed the genus 

 Dendrochilum so as to include within it all orchids hitherto 

 placed under Platyclinis and Acoridium. These two genera 

 are now reduced to the rank of subgenera or sections. This 

 arrangement appears to have received the approval of botan- 

 ists generally and has been adopted by Ames, and also by 

 Pfitzer and Kranzlin in their monograph of the Coelogyninae 

 (Das Pflanzenreich) . 



Spathoglottis papuana, Bail., var. puberiflora, var. nov. 



Flowers, ovary and pedicel beset with minute setaceous 

 hairs; pedicel + 15 mm.; unimpregnated ovary almost cylin- 

 drical, about same length as pedicel. Segments of perianth 

 subequal in length and almost similar, the paired petals being 

 very slightly longer than the other segments. 



Lateral sepals free, ovate-elliptical, +17 mm. long by 

 + 10 mm. broad, with one dark central vein and several 

 lighter parallel veins on either side. Dorsal sepal ovate, 

 cucullate, accuminate, + 17 mm. long x 10 mm. broad; dark' 

 central nerve with several parallel nerves on either side. 

 Lateral petals ovate-elliptical with dark central nerve and 

 several parallel nerves on either side, + 18 mm. long x 10 mm. 

 broad. Labellum sessile, 3-lobed, + 14 mm. long; middle 

 lobe with an obcordate veined tip about 7 mm. wide, passing 

 backwards by a narrow isthmas to its junction with the lateral 

 lobes and there dilating into a trapeziform expansion; the 

 lamina with a rather small conical callus about the middle of 

 the isthmus, another very large bilobed somewhat pyramidal 

 callus arising in the posterior dilated portion of the isthmus, 

 the surface behind the large callus pubescent and traversed by 

 2 parallel longitudinal lines; the lateral lobes erect or slightly 

 incurved, oblong with entire margins, each about 7 mm. long. 



Column semi-terete, slightly incurved, gradually expand- 

 ing laterally from below upwards, +12 mm. long; anther 

 lid-like, terminal on anterior surface of the apex; stigma 

 transverse, oblong, rather shallow, situated immediately below 

 anther; rostellum widely triangular with a rather blunt apex, 

 situated on upper margin of stigma, inclined forward, not very 

 prominent.
