12. Geissois racemosa Labill.

Sertum austro-caledonicum 2: 50, tab. 50 (1825). — Type (as given in protologue): none. — Lectotype (here designated): “Herb. Webbianum, ex Herb.Labillardière, Austro- Caledonia”, Labillardière s.n. ( FI [image]!, Herb.Webb no. 060970 [buds, old fl. and y.fr.]; isolecto-, BM! barcode no. 000600408, FI [image]!, Herb. Webb. no. 060971 p.p. [excl. fragment with persistent stipules], K!, P!).

Remarks

The lectotype consists of two fragments, one with leaves, old flowers and young fruit, and the other is a length of twig with racemes of buds; beneath the material are seven or eight pieces of paper containing a handwritten description and notes. A second sheet at FI comprises three fragments with leaves, one of which has racemes attached, plus a detached raceme.Two of the fragments have leaves and/or stipules that correspond reasonably well with G. racemosa but the third, which is sterile, has persistent stipules and is probably G. montana , and so is excluded from the isolectotype.

The sheet at K does not indicate that it was collected by Labillardière but has “Mr Webb” written next to the stamp for Herb. Hooker, and “ Geissois racemosa Lab., Austro-Caledonia ” on the label. It is a good match with the lectotype , as are the sheets at BM and P. The duplicates at BM, K and P were probably distributed after the original publication of the name as all indicate “ G. racemosa ”, suggesting that Labillardière may have had access to several duplicates when he described this plant, and so the first FI sheet is a lectotype , rather than a holotype.

The name G. racemosa has occasionally been misapplied, for instance by Lindley to refer to material of G. magnifica (q.v.). The species illustrated by Heckel (1912: pl. 13 and probably also pl. 14) under the name G. racemosa appears to be G. pruinosa , although the text probably includes material of several taxa under this name.
