Kurz, Prrax, King’s Collector. Matacca, Maingay (Kew Distrib. 1446).— 
DISTRIB. Sumatra. 
An evergreen tree, variable in pubescence; branchlets terete. Leaves 3-8 in. 
rather thin, almost membranous, midrib and 8-10 pair of nerves beneath hairy, cross- 
nervules faint or strong; petiole 1-3 in. Male racemes (in Andaman specimens) 
3 in.; flowers minute, glabrous, in crowded clusters; buds ovoid, acute, j; in, 
long; stamens about 30, filaments free or connate, anther-cells separated by a 
truncate thick warted connective. Fem. racemes larger than the males, stouter ; 
bracts lanceolate, caducous ; calyx obliquely urceolate, entire or 2-3-cleft, deciduous ; 
style very stout, puberulous or glabrate, stigmas rather short. Capsule (in Perak 
Specimens) '$ in. diam.; cocci globose.— The Perak specimens have more hoary 
branchlets, petioles and fem. racemes than the Malaccan. I refer this to M, acumi- 
natus, of which Mueller says stamens 60, rather than to the Sumatran M. longi- 
Jolius, in which he states them to be (as they are in this) about 27-30; he further 
adds ander longifolius that it is extremely like acuminatus, but that besides the 
number of stamens it differs in the rather longer and slender spines of the capsule, 
and in the shorter style. Kurz says of his acuminatus that it is frequent in the 
Andamans, and that the leaves are either peltate or cordate, but I have seen no. 
Specimens from thence. I have not cited the synonyms of M. acuminatus given by 
Mueller, feeling doubtful about the species. 
10.2 M. Helferi, Muell Arg. in Linnea xxxiv. 190, and in DC. 
Prodr. xv. ii. 968 ; branchlets young petioles and racemes sparsely stellate - 
pubescent, leaves nearly glabrous alternate long-petioled ovate- or linear- 
oblong caudate-acuminate sinuate-toothed obscurely glandular beneath base 
rounded or subcordate not peltate 3—5-plinerved, male racemes slender, buds 
minute obovoid nearly glabrous, fem. racemes elongate, calyx spathaceous, 
ovary clothed with short stout soft spines, style twice as long as the 
stigmas. P Kurz For. Fl. ii. 384. 
TENASSERIM ; Koloukhin Island in the Saluen River, Helfer (in Herb. DC.); 
ergui, Helfer (Kew Distrib. 4731). Ma acca, Maingay (Kew Distrib. 1446). 
Branches slender, but woody, tips and racemes sparsely glandular. Leaves 3-6 in., 
rather membranous, greenish when dry; nerves very slender, 6-8 pair above the 
short basal, often pubescent beneath; basal glands 0; petiole 1-13 in. Male racemes 
filiform ; bracts minute, 2-4-fld.; flowers 4j in. diam. ; sepals 3-5, lanceolate ; 
stamens about 20; anther-cells separated by the truncate tubercled connective, 
Which sometimes is produced above them. Fem. racemes 6-8 in., many-fld. ; calyx 
sPathaceous ; ovary pubescent and clothed with soft turgid nearly glabrous spines ; 
‘tyle stout, twice as long as the short reeurved papillose stigmas.—The male flowers 
are described from Mergui and the fem. from Malaccan specimens. It is possible 
at they may not be conspecific. Kurz says of Hedferi that it is very common all 
over Burma from Pegu to Tenasserim and the Andamans, but I have seen only 
Helfer’s male specimens, and as he described the style as short, I doubtfully quote 
m. It differs from acuminatus chiefly in the not peltate leaves and ovary not being 
densely hispid,
