in Java, and, according to Prain, in Indo-China, wild in Silhet, Caehar, and 
Chittagong. 
Inga timoriana DC. was reduced by Bentham to Parkia roxburghii G. Don, 
and following the principles of priority, the earliest specific name must be 
adopted. In order to be sure of the identity of the Philippine plant with 
DeCandolle’s species, material comprising flowers, fruits, and leaves of the 
Philippine plant, as well as fragments of two species cultivated in the Botanic 
Garden at Buitenzorg, labeled Parkia intermedia Hassk., and P. roxburghii 
G. Don, was sent to M. C. DeCandolle for comparison with the type of Inga 
timoriana DC. I am indebted to him for the following statement: “I have 
entrusted to M. Buser the comparisons you desired to be made of three specimens 
of Parkia with Inga timoriana DC. and Parkia Roxburghii Don, and of the latter 
with what we have here under P. intermedia Hassk., in view of ascertaining if 
they are distinct species. M. Buser has submitted to me his following conclusions 
in which I entirely concur. 
“ ‘Taking for the type of Parkia intermedia Hassk. the plant distributed under 
this name by Zollinger (n. 3586) there exists a complete identity with intermedia 
for the plant “ex Hort. Bot. Bogor. cult.” under the name of P. Roxburghii, but 
not for the plant labeled, ibidem, P. intermedia Hassk. 
“ ‘P. intermedia Hassk. ( =Zollinger n. 3586, n. 736) and P. Roxburghii G. Don 
(Wall. Cat. 5288) are certainly two distinct species (see leaflets and floral 
characters ) . 
“ ‘Inga ? timoriana DC. is the same plant as Barnes 323 = P. intermedia Hort. 
Bogor. cult., and quite different from true P. intermedia Hassk. In a broad 
sense it may be identified with P. Roxburghii Don, as done by Bentham; in a 
more restricted specific conception it may be regarded as a species of secondary 
order. 
“ ‘Roxburghii: rhachide rotundato-angulata, foliolis utrinque glaberri- 
mis, margine adpresse ciliatis, subconcoloribus, costa tenui, nervis secun- 
dariis inconspicuis, rhachilla tenuiore. Corollae segmentis extus hirsutis. 
" ‘Timoriana : rhachide quadrangulari, foliolis utrinque, supra prae- 
sertim, plus minus pilosis, subtus pallidioribus, costa latiuseula, nervis 
secundariis supra subreticulate-prominulis, rhachilla latiore; corollae seg- 
mentis (Barnes 89) glaberrimis.’ ” 
The specimens sent for comparison were For. Bur. 323 Barnes (leaves and 
fruits), with flowers of For. Bur. 89 Barnes from the same locality (Lamao 
River, Province of Bataan, Luzon), and two specimens from trees cultivated in 
the Botanic Garden at Buitenzorg, Java, one labeled “Cult, in Hort. Bog. I, B, 51, 
Parkia intermedia Hassk.,” which is not Hasskarl’s species, but is Parkia 
timoriana, and the other labeled “I, B, 4 = 48 = 50, Parkia Roxburghii Don,” 
which is not Don’s species but is P. intermedia Hassk. Prain 21 who has worked 
over the species of Parkia occurring in the Malay Peninsula, also expresses the 
opinion that P. roxburghii Don, and P. intermedia Hassk., are distinct. Com- 
parative studies with a full series of specimens of typical P. roxburghii G. Don, 
and P. timoriana may show the distinguishing characters indicated above to 
be constant, and the two species worthy of specific rank, a point that is left 
for some future monographer to decide.
