REMARKS

The holotype at G has narrowly elliptic leaves which are glaucous on the underside (“A”). At P, seven sheets have material labelled Vieillard 2077, most with the locality Wagap and dated 1861-1867, and an eighth lacks a collector’s name and number but has material matching “A”. Four of the sheets have material of “A” only, while others have fragments with thicker, ovate leaves and fruits (“B”), either alone or mounted with “A”. However, on one sheet ex CN, material matching “A” and “B” are attached to the same stem, indicating that “B”, with occasional 3-foliolate leaves, is the basal/juvenile foliage of “A”, and from the same gathering. Other sheets at P and K have separate fragments of “A” and “C”, which is probably Vieillard 594. Finally material on one sheet at P labelled Vieillard 2077, Wagap, 1861-1867, is neither “A” nor “B”, though it may be “C”, but in any case it has the wrong label and is not an isotype.

Pancheria obovata var. crassifolia is a synonym of P. billardierei . The leaf shape in the holotype is compatible with this name, and the waxy layer on the underside that causes the glaucous appearance is unusual in Pancheria , but occurs commonly in P.billardierei (e.g., Bradford et al. 1058, 1078, 1198, all K, MO, NOU).
