Palaquium dasyphyllum Pierre ex Dubard, Bull. Soc. Bot. France 56 (Mém. 16): 8 (1909).

– Isonandra dasyphylla de Vriese in Natuurk. Tijdschr. Ned.- Indië 21: 307 (1860), nom. illeg. non Miq. (1852). – Type: Borneo, [Kalimantan], Banjarmasin, Teysmann H.P. 5066 (holotype P [ P00645624 ]).

Palaquium beccarii Pierre ex Dubard, Bull. Soc. Bot. France 56 (Mém. 16): 20 (1909). – Type : Borneo, Teysmann H.P. 5068 (holotype P [ P00645625 ]), syn. nov.

Notes. There is a second collection in the Paris herbarium ( Beccari 3347 [P00640328]; Figure 2B ) labelled with the name Palaquium beccarii that is not cited in the protologue. Confusion arose when van Royen (1958) made the new combination Aulandra beccarii and wrongly cited the type as Beccari 3347. The combination is valid and legitimate but applies to the species that is typified by Teysmann H.P. 5068 (see Figure 2A ), which has now been identified as Palaquium dasyphyllum . This leaves the species that includes Beccari 3347 (hitherto known as Aulandra beccarii ) without a name. As changing the type is not permitted without a conservation proposal, and as these are relatively unknown species for which a conservation proposal may not be appropriate, we prefer to describe it here under the name Palaquium aulandrum .

When van Royen (1958) transferred Palaquium beccarii to Aulandra , he provided a description based on the collection Beccari 3347. We have verified and adapted van Royen’s description as well as the description in the Tree Flora of Sabah and Sarawak ( Chai & Yii, 2002) and given the type as Beccari 3347, the only known collection of this species, in order to validly publish the species with a different name in the sense that van Royen intended.

As ‘ beccarii ’ is not available for the epithet of a new species in Palaquium , the new epithet ‘ aulandrum ’ is given to reflect the species’ former placement in the genus Aulandra .

Palaquium longifolium (H.J. Lam) A.Phang , comb. nov. – Aulandra longifolia H.J.Lam, Bull. Jard. Bot. Buitenzorg , sér. 3, 8: 415, f. 6 (1927). – Type: Borneo, [Kalimantan], Loembis, Amdjah 238 (lectotype L [ L0006113 ], designated by van Royen (1958); isolectotypes BO [BO-1359858, BO-1359859, BO-1359860]).

Aulandra cauliflora H.J.Lam , Hooker’s Icon. Pl. 34: t. 3360 (1938). – Type: [ Malaysia], Sarawak, IVth Division, Near Long Kapa, Mount Dulit (Ulu Tinjar), Richards 1125 (holotype K [ K000777765 , K000777766 ]).

Notes. The holotype of Aulandra cauliflora is mounted over two sheets which are clearly labelled as Sheet 1 and Sheet 2 of the same specimen, hence constituting a single specimen under Article 8.3 of the Shenzhen Code (Turland et al., 2018).
