ABSTRACT

Recent field work in Lao PDR and the Malaysian state of Sabah produced multiple collections of a large-flowered Ipomoea that appeared to be the same species. The disjunct distribution, however, seemed anomalous. Checking type images and other specimens led to the name I. cambodiensis Gagnep. & Courchet, described from Cambodia. A full description, distribution map, discussion of the taxonomy, ecology, and perceived relationships, plus a compilation of all specimens seen to date are provided for this enigmatic and heretofore little known species.

RÉSUMÉ

Ipomoea cambodiensis Gagnep. & Courchet (Convolvulaceae) requalifié avec des notes sur leur distribution et l'écologie.

Les prospections récentes en RDP Lao et dans l'état malaisien de Sabah ont fourni des récoltes nombreuses d'un Ipomoea à grandes fleurs, apparemment de la même espèce. La répartition disjointe semblait cependant anormale. Une comparaison avec les images des types et d'autres spécimens a conduit au nom Ipomoea cambodiensis Gagnep. & Courchet, décrit du Cambodge. Une description complète, une carte de répartition, une discussion taxonomique, l'écologie et les affinités envisagées, ainsi qu'une compilation de tous les spécimens vus à ce jour ont été fournies pour cette espèce énigmatique et jusqu'ici peu connue.
