Descriptive Notes on Papuan Plants, 
Except the bearded petals all the above-mentioned characteristics dis- 
tinguish also M. macrocarpa (Wall. Plant. Asiat. rarioFj i. 43, t. 47). 
Mucuna monosperma (Cand. Prodr. ii. 406) is easily separated by 
broader leaflets on longer stalks, by more expanded corymbs, short lobes 
of the calyx, straighter lower petals and perhaps its fruit. M. Novo- 
Guineensis (Scheff. Annal. du Jard. Bot. de Buitenz. i. 18) is also de- 
scribed as producing only short teeth of the calyx, with an inflorescence 
of 5 inches in length and comparatively large leaflets ; but in respect 
to the latter characteristics M. Bennetti may be subject to variations. 
The petals of Mr. Tijesmann’s plants are brilliantly orange. Baker (in 
J. D. Hooker’s Flora of British India, ii. 185) mentions as perhaps 
allied to M. imbricata (Cand. Prodr. ii. 406) the as yet undescribed M. 
acuminata (Grab, in Wall, list, 5621); this seems allied to our plant 
in respect to the lobes of the calyx, but the petals are shorter according 
to Baker’s note. 
Mucuna Albertisi. 
Branchlets and petioles rusty-toinentose ; lateral leaflets oblique 
rhomboid-orbicular, the terminal roundish, all slightly pubescent and 
scantily hispid above, almost brown velvet-downy beneath; panicle con- 
sisting of several short racemes; pedicels shorter than the calyces or 
hardly as long, with them velvet-downy and partially hispid ; teeth of 
the calyx shorter than the tube ; lateral and lower petals almost of 
equal lengthy upper petal about one-third shorter ^ the lower petals very 
narrowj gradually falcate ; the five shorter anthers woolly -bearded ; the 
five longer anthers somewhat hairy ; style and ovary beset with 
oppressed hair. 
On the Fly-River ; D’ Albertis. 
Stem probably woody. Length of the petiole up to the lateral leaflets 
usually about 3 inches, rarely much shorter. Stipules early deciduous 
or inconspicuous. Stipellae subulate, hardly exceeding 1 line. Leaflets 
of firm consistence ; their length mostly from 3 J to 5 inches ; the lateral 
nerves and also the veins beneath prominent; the apex of the leaflets 
often slightly acuminated. General peduncle a span long or variously 
shorter. Racemes few-flowered or branched, forming almost corymbose 
or cymose clusters or bunches. Bracts lanceolar, acuminate, 3-4 lines 
long, early dropping. Calyx inch long; the upper lip deltoid, 
usually about 2 lines long ; the lateral lobes of the lower lip hardly 
above 1 line long, lanceolar- deltoid ; the lowest lobe nearl}^ 3 lines 
long, narrowly semilanceolar. Upper petal orbicular-ovate; lateral
