This is apt, when its leaflets are unusually small, to simulate P. contortum from 

 which it is, however, easily distinguished by its smaller fruits, its pedicelled florets, 

 and its terete branchlets. It is also apt, when its leaflets are unusually large, to 

 simulate P. angulatum ; as both have angular branches and pedicelled florets the 

 only safe diagnostic character is the nature of the glands, especially those on the 

 partial rachises of the pinnae; these glands are stipitate in P. Clypearia, sessile in 

 P. ungulatum. 



There is just a trace of doubt as to whether this is Rumphius' Clypearia rubra 

 since that author figures no glands, or even that it is Inga Clypearia Jack, since 

 Jack says there is no petiolar gland on the leaf of his species. Jack's plant is, 

 he says, known in Sumatra as " Jiring muniet."

III, 306. A tree 25-30 feet high with spreading shortly puberulous 

 angular branches, bark dark-brown. Leaves evenly 2-pinnate ; rachis 

 angular, puberulous, 3-8 in. long, with a large sessile gland "5-*75 in. 

 above the base and near the middle of the petiolar portion, foliar 

 portion with smaller sessile glands below the bases of all but the 

 last pair of pinnae set obliquely on the upper truncate ends of sharp-edged 

 ridges ; pinnas 2-4-jugate, their rachises with similar but small glands 

 just below each pair of leaflets, the distal 6-7 in., the lowest 1-1'5 in. 

 long; leaflets of upper pinnae 5-8- jugate, of lowest 2-3- jugate, all 

 diminishing downward ; terminal leaflets of most of the pinnae 3*5-6 

 in. long, 1*25-2 in. wide, ovate-lanceolate, gradually tapering to an ncuto 

 tip, the base wide-cuneate, the midrib central, the bases of the remainder 

 progressively more obliquely rounded and the midribs progres- 

 sively more diagonal, proximal leaflets 1 in. long, *75 in. wide ; all 

 membranous, sparsely puberulous above, softly pubescent beneath when 

 young ; thinly subcoriaceous, dark-green glabrous shining above, 

 dull puberulous beneath when mature, lateral nerves 5-7 pairs rather 

 prominent beneath ; petiolules '07 in. long. Flowers in small sub- 

 umbellate corymbs '5 in. across, on short peduncles 75 in. long, fascicled
