108 DOUBTFUL SPECIES. 
DALBERGIA PINNATA (Derris pinnata Lour. Flor. Cochin-Chin. 432). 
Usually referred to D. tamarindifolia. There are, however (vide ante p. 49), certain features in 
Loureiro's description that are antagonistic to this identification and the species, which is obviously 
a Dalbergia, is more likely to be D. DMillettii than to be JD. famarindifulia. The point сап only be 
settled in the field by the botanists of Cochin-China and for the moment it is more advisable to 
treat this as а species of doubtful identity. tig 
DALBERGIA PURPUREA?  Laness, Pl. Util. Col. Franç, 289 (1886), not of Wall. 
То this species Lanessan gives no clue, the only certainty is that it is not Wallich's tree of the 
name; it would hardly matter if it were, since Wallich's name is a mere synonym. The probability 
is that this is one or other of group of four known as Cám dai in Kmer, It has been tentatively 
suggested that it is the same as D. dongnaiensis, which is the only one of the four where the flowers 
are known, and which happens to have them blue. | 
DALBERGIA SAIGONENSIS Pierre MSS. 
Referred in this paper (vide ante p. 89), as a variety, to D. paunicu!ata. This tree may, however, 
when flowers aro reported, prove to deserve the specific rank claimed for by M. Pierre, in which case 
Pierre’s name will stand. 
DALBERGIA YOLUBILIS Llanos Mem. Acad. Cienc. Madr. (1858), not of Roxburgh. 
All that Llanos says of this is:—“ pod linear, subinourved," which is enough to prove that his 
plant is not Roxburgh’s. The identification he suggests presupposes a climbing habit, and the only 
climbing Dalbergia in the Philippines of which it could possibly be said that the pods are “linear” 
is D. polyphylla : this identification (vide ante, p. 71) is, however, purely tentative and conjectural.
