29. Hypericum dolabriforme Vent., Descr. Pl. Nouv.: tab. 45. 1801.

Lectotypus (designated by Robson, 1996: 123): U NITED STATES. Kentucky: Michaux s.n. (G [G00341526]!; isolecto-: P [P01901389, P02442087, P02442088, P02442089, P02442090]!, P-JU n° 11841 [P00667214]!, P-MICH [P00667207, P00667217]!).

Notes. – Hypericum dolabriforme is endemic to the southeastern regions of the United States (from southern Indiana to northwestern Georgia) (Robson, 1996). Only a single specimen exists in Ventenat’s herbarium, i.e. the Michaux collection from Kentucky. Michaux (1803: 81) validated the name H. procumbens Michx. [nom. illeg.] [non Desf. ex Willd.] based on the same material. Robson (1996: 123) implicitly lectotypied Ventenat’s name by referring to the unique specimen at G. A collection of this species given by Ventenat to Jussieu from Cels’s garden in 1803 is here considered as original material (P-JU n° 11832 [P00667211]).
