Disperis guttata Frapp. ex Cordem.

Fl. La Réunion: 254 (1895); Schlechter , Bull. Herb. Boiss. 6: 955 (1898). — Disperis guttata Frapp., Cat. Orch. La Réunion: 10 (1880), nom. nud., type not designated .

No herbarium specimen of this species is known and CORDEMOY ’S description is very imperfect. The only significant characters noted by him are as follows “feuilles alternes, fleurs petites et rosées, sépales lateraux parsemés de grosses taches vertes”. This last character has not been seen in any of the known species. Disperis discifera var. borbonica possesses green or brown stripes, but on the petals not the lateral sepals. That described by DE CORDEMOY is perhaps this taxon but we cannot be sure and it is better, as done by SCHLECHTER in his monograph, to consider this name a doubtful one.

The herbarium of DE CORDEMOY (MARS) contains an herbarium specimen of D. discifera var. borbonica but misidentified as D. tripetaloides . This specimen came from “Plaine Fourgères”, but the locality indicated by DE C ORDEMOY for D. guttata is “ St. Pierre (Tampon)”. This specimen cannot be that used by DE CORDEMOY to make his description of D. guttata .
