x.c, 1 Merrill: New or Noteworthy Philippine Plants, XI H 



Samar, Mount Cauayan, Phil. PL 1637 Ramos, April, 1914, on forested 

 slopes. 



The most striking character of this species is its cauline inflorescence. 

 It is manifestly allied to Pithecolobmm paucifiorum Benth., but differs 

 not only in the disposition of its inflorescences, but in its very differently 

 shaped, more numerously nerved leaflets. In vegetative characters it 

 closely resembles Pithscolobiuni bigeminum Benth. as i-epresented by 

 Thwaites C. P. eU- 



PITHECOLOBIUM MULTIFLORUM sp. nov. 



Arbor 6 or 8 m alta partibus junioribus inflorescentiisque 

 plus minusve f errugineo-pubescentibus ; foliis circiter 40 cm 

 longis, bijugatis, piri'nis inferioribus 4-foliolatis, superioribus 

 8-foliolatis, foliolis subcoriaceis, oblongis vel oblongo-lanceolatis, 

 breviter obtuse acuminatis, basi acutis ad subrotundatis, usque 

 ad 14 cm longis, nervis utrinque circiter 9, subtus prominentibus ; 

 paniculis terminalibus, quam folia longioribus, e basi ramosis, 

 multifloris; floribus subcapitatis, capitulis 4- vel 5-floris, in 

 ramulis plus minusve confertis, petalis fere liberis. 



A tree 6 to 8 m high, closely allied to Pithecolobium elHpticum 

 Hassk., the branches dark-colored when dry, glabrous or nearly 

 so, the branchlets sparingly brown-pubescent with short hairs, 

 the primary and secondary rachises of the leaves and the in- 

 florescence with similar hairs, the younger parts of the inflores- 

 cence densely ferruginous-pubescent. Leaves about 40 cm long, 

 evenly 2-jugate, the rachis about 10 cm long, with a single very 

 large and prominent gland about 1.5 cm above the base, none 

 between the pinnae; lower pinnae 2-jugate, the rachis about 

 3.5 cm long, with a gland between the petioles of the distal 

 leaflets; upper pinnae 4-jugate, about 30 cm long, with a large 

 gland between the upper two pairs of petiolules, the lower two 

 leaflets alternate, the others opposite. Leaflets subcoriaceous, 

 oblong to rather broadly oblong-lanceolate, entirely glabrous, 

 shining, brownish-olivaceous, the lateral ones somewhat falcate 

 or inequilateral, shortly and bluntly acuminate, base acute to 

 somewhat rounded, or at least rounded on one side of the petio- 

 lule, the lower ones smaller than the upper, 8 to 14 cm long, 

 3.5 to 5 cm wide; lateral nerves about 9 on each side of the 

 midrib, prominent; petiolules about 5 mm long. Panicles term- 

 inal, ample, many-flowered, branched from or near the base, 

 as long as or longer than the leaves, the lower branches up to 

 40 cm in length, the secondary branches in the upper two-thirds. 

 Flowers in small heads on the ultimate branchlets, the heads 

 4- or 5-flowered, often crowded, the subtending bracteoles ovate, 

 about 1 mm long. Calyx brown, about 3 mm long, rather
