256 MR. J. G. BAKER ON THE 
subacutis rigide coriaceis integris utrinque viridibus subtus reticulato- 
venulosis, floribus masculis ignotis, floribus foemineis in cymas copiosas 
axillares pedunculatas paucifloras dispositis, perianthii parvi segmentis 
ovatis, ovario globoso glabro dense echinato stylo persistente hispido 
fructui zquilongo coronato. 
A tree, glabrous in all its parts, with slender terete woody 
branchlets. Leaves crowded, alternate, ascending; petiole j in. 
long; blade 2-3 in. long, about 4 in. broad, narrowed gradually 
from the middle to the base, quite entire, firm in texture, green 
on both surfaces, paler beneath, the 7-8-jugate arcuate ascending 
main veinlets and copious intermediate areole all distinetly 
visible. Female flowers one or few on copious ascending slender 
glabrous lateral peduncles and distinctly pedicellate. Perianth 
glabrous, subcoriaceous, ;5 in. long. Ovary globose, j in. in 
diam. in the fruiting stage, when it slits down one side from top to 
bottom, densely beset with brown coriaceous bristles half as long 
as itself and crowned with 1 rarely 2 cylindrical hispid persistent 
filiform entire styles. Seed 1, globose, black, glabrous.—

MACARANGA ALNIFOLIA, n. sp. 
Arborea, glabra, foliis oblongis acutis rigide subcoriaceis utrinque 
viridibus glabris venis primariis 10-12-jugis erecto-patentibus exsculptis, 
floribus fcemineis ignotis, floribus masculis in glomerulos globosos 
panieulatos dispositis, perianthii glabri campanulati segmentis ovatis, 
staminibus paucis. 
A tree, with terete woody branchlets, glabrous in all its parts. 
Leaves alternate; petiole 1-13 in. long; blade 4-5 in. long, 
2 in. broad at the middle, quite entire, acute, not acuminate, 
deltoid at the base, moderately firm in texture, green and 
quite glabrous on both surfaces, the 10-12-jugate erecto-patent 
main veins only raised beneath. Male flowers in copious 
peduncled axillary panicles longer than the petioles, arranged in 
dense globose clusters, but seen only in the bud-stage. Perianth 
globose, glabrous.—Central Madagascar, Baron 1404! This and 
the two succeeding species, so far as can be judged from the 
material, fall in beside M. boutonioides and obovata ; but female 
flowers are needed to settle their position definitively. M. cupu- 
laris, Müll. Arg. in DC. Prod. xv. 2, p. 1008, of which the original 
is at Kew, is identical with a plant distributed by Bojer under 
the name of M. ciliata from Johanna island.
