34. Carpinus rupestris A.Camus

Bulletin de la Société botanique de France 76: 966 ( Camus 1930). – Type: s. loc., s. coll., eventually J. Cavalerie 4560 (lecto-, designated here: P01903242!; isolecto-: P01903240!, P01903241!). – Additional type material: China, Kouy-tchéou [Guizhou], Houang-tia-pa [Houang-ts’ao-pa], grands rochers, J. Cavalerie 4560 (syn-: A00033766!, E00240621!, K!); ibid., [Guizhou], Hiny-hien [missionary station in SW of Guizhou, NW of Xingyi city, Hsien-i-fu, 興義府], rochers, J. Cavalerie s.n. (syn-: P01903239!). – Note: the specimen designated here as lectotype bears an annotation by Camus, so it is original material, but it lacks (as do the isolectotypes) an original label by Cavalerie. The specimen P01903242 bears a written note on an extracted page with the protologue that “ Cavalerie 4560 ” is apparently missing in the Paris herbarium. Possibly, the original label became detached and is lost. The specimens P01903240–2 are not duplicates of the other syntype P01903239, which has male catkins and narrower leaves. In addition, P01903241 and P01903242 contain infrutescences.
