5. Pancheria beauverdiana Pamp. View in CoL

Annali di Botanica ( Rome ) 2: 100 (1905) . — Type (as given in protologue): “In collibus circa Wagap [Vieillard, – Herb. de La Nouvelle Caledonie, n. 594 (pr. p.)] – sub P. pirifolia Brogn. [sic] et Gris – specimen foem. – (D C)”. — Holotype: In collibus circa Wagap, 1868 [hand-written], fr., Vieillard 594 (G! ex DC G00016977 ; iso-, K!).

REMARKS

The holotype at G has a single fragment for which the collection date was probably 1861-1867. The material has leaves in whorls of three, which are mostly simple, elliptic to rhombic, and narrowly cuneate at the base into a petiole c. 1 cm long. The largest leaf blade (c. 6 × 2.2 cm) has teeth almost to the base. Two leaves with longer petioles (c. 2.5 cm), each bearing a single, asymmetric, narrowly elliptic articulated leaflet, are remnants of 3-foliolate leaves, and these lateral leaflets also have teeth almost to their base. The stipules are ovate and abaxially hairy, and the capitula in fruit are c. 9 mm in diameter .

The remnants of the compound leaves in this specimen are similar in size, shape and the distribution of their teeth to the leaves of material previously identified by us as Pancheria aemula (in which the leaves are commonly 3-foliolate but can be a mixture of 1-5-foliolate). These features also distinguish the holotype of P. beauverdiana from P. billardierei , in which the juvenile foliage can be compound, but then the leaflets are broader and usually only distally toothed. The main difference between the holotype of P.beauverdiana and material previously determined as P. aemula is in the stipules, which are similar in shape but usually glabrous in P. aemula . Despite this, P. aemula , and hence also P. rivularis , appear to be conspecific with P. beauverdiana , and the latter epithet has priority.

A sheet of Vieillard 594 at P (in collibus circa Wagap, 1861-1867, P00143086 ) has three fragments with capitula in fruit, and the label has been annotated “ Pancheria beauverdiana Pampan ?”, probably by Guillaumin. The leaves resemble some of the small distal leaves of the holotype and the stipules are also a reasonable match. However, the sheet at P has no larger simple leaves and no compound leaves, and so is it not certain that it is from the same gathering as the type.

The epithet beauverdiana refers to Gustave Beauverd (1867-1942), who was a Swiss botanist and artist ( Stafleu & Mennega 1993) and curator of Herbier Boissier at the time when Pampanini was studying Cunoniacaeae in Geneva.
