Paphiopedilum barbatum

Paphiopedilum barbatum (Blume) Pfitzer

Described: Blume in Catalogus, 98 (1823)
Transferred: Pfitzer in Pringsheim, Jahrbcher fur wissenschaftliche Botanik, 19:163 (1888)
Etymology: Derived from the Latin barba, meaning beard. I assume this is in reference to the hairs present at the bases of the floral parts and on the ovary and inflorescence. I have not yet reviewed Blume's Catalogus to confirm this.
Varieties & Forms: none

Cypripedium biflorum B.S. Williams in The Orchid Grower's Manual, ed. 3: 109 (1868)
Cypripedium nigritum Reichenbach fil. in Gardener's Chronicle, 2nd series, 18: 102 (1882)

Cribb 1998 lists Lindley's description of Paph. barbatum in Edwards Botanical Register in 1841 & 1842 as the place of original description. Until I review a copy of Blume's Catalogus from 1823, I can't say one way or the other.
