DOUBTFUL AND EXCLUDED SPECIES. 
DOUBTFUL SPECIES. 
DALBERGIA AESTIVALIS Pierre MSS. 
Only a leaf-specimen of this proposed species has been available for study. It is certain] y 
quite different from any of the other Dalbergias in Herb. Pierre, but it cannot as matters stand be 
distinguished from D. Oliveri Gamble and is almost certainly identical with Gamble's tree. Tho 
difficulty does not lie so much in any doubt on this point as in the possible identity of D. aestivalis 
with D. /aecifera Laness. The rote on the ticket reads:—* Dalbergia aestivalis Pierre. — Crescit in 
vicinibus Song-lu in prov. Bienhoa. Arb. 20~—80-metr. Moi. Chleu lai Bon dam (dotime), Ann. 
Сау cam lai." 
DALBERGIA ENTADIOIDES Pierre MSS. 
This is known only in leaf and flower: it cannot be se parated from D. foliacea Wall. by its 
flowers ; the leaflets, however, though of exactly the same shape, are glabrous beneath. If when fruits 
are reported this is found to deserve specifio rank, Pierre's name must be taken up for the epecies. 
DALBERGIA LACCIFERA Laness. Pl. Util. Col, Franç, 289 (1886). 
“(Еп Kmer. Dom-chloeu-snucl) Arbre de 20 à 25 métres sur 40 à 60 centimetres de diamétre, 
Bois gris brun, excellent pour le placage. Il sert à élever le Coccus lacca et les Cambodgiens prétendent 
qu'un arbre donne de 10 à 20 kilogrammes de laque par année." This note by Lanessan is an irdiffer- 
ent substitute for the description that is expected with a proposed new species. The name is not used 
by M. Pierre in his Herbarium; none of Pierre's specimens are noted as taken from a (595 on which 
Coccus (асса is raised; we are therefore left with no guide except the vernacular name. “ Snuol ” 
does not assist greatly, since it is noted by Pierre as being applied both to D. paniculata and to 
D. Hemsleyi ; the first species may be excluded since its timber is not suitable for veneering. We aro 
therefore left to decide whether we have here to deal with D. Hemsleyi, or with D. acstivalis, to 
which latter the two names “dom” and “chlceu” are known from Pierre's notes to be applied, and 
are apparently restricted. Тһе likelihood is therefore clearly greater that D. laccifera and D. aestivalis 
are the same tree; if th's be so, then D. Oliveri and D. laccifera are almost certainly identical. 
The matter must be left to botanists in French Indo-China to settle; the important point is that, 
if the two be really the same, the name D. laccifera must replace the name D. Olireri. 
DALBERGIA LANCEOLARIA? Llanos Mem. Acad. Cienc. Madr. (1858), not of Linn. f. 
This is said to have the “pod linear, silky," which effectively disposes of the identification 
proposed by Llanos. The ovary of D. AMinahassae, a species allied ю D. lanceolaria that does occur 
in the Philippines, is densely silky and it is possible that its pods, which are not yet reported, 
may also be silky. But this suggested identification is only tentative ; U besides it must not be 
forgotten that Lamarck disarranged the original D. €—' by referring. to that species | Derris 
(Brachypterum) scandens. If Llanos relied on Lamarck 8 citations when he identified his Philippine 
plant, he may very well be referring to a species of Derris. |
