2el. Var. MICRACANTHUM subvar. Makanaro Becc. It differs from the preceding 
in the fruits being a little larger, globular, 27—28 mm. in diameter. It forms a 
link with the variety ceramense. Rumph’s “Lapia Macanaru” is quite another 
plant from the above, and is the Metroxylon longispinum of Martius (M. Rumphii 
var. longispinum Becc.) to which Rumph assigns a fruit as big as a hen's egg. 
and therefore not at all corresponding to our “plant.

DrscRiPTION.— Probably not diftering in habit from the typical M. Rumphit 
Fruit very small, globose, 18—20 mm. in diameter, flattish or slightly concave 
above, and minutely beaked., the base roundish or slightly unequal ; scales in 18 
vertical series, the largest 5 mm. broad in the exposed part, and with the apices 
slightly produced and obtuse, faintly grooved along the centre, glossy, sttaw- 
coloured with a narrow dark intra-marginal line and narrowly discoloured finely 
erose-ciliate margin; the pericarp relatively thick and spongy, eSpecially at the 
base.. The seed has the albumen homogeneous, horse-shoe shaped in vertical 
section, and the embryo basal, exactly as in the typical forms of Metroxylon.

HanmrraT.—[t is distinguishable by its very small, globose, not depressed fruits 
having the scales darker than in any other variety, and a relatively thick 
pericarp of uniform thickness all round. .I have considered var. buruense as 
referable to M. Rumphii, but it could be as well related to M. Sagus as it is 
not known if it has spinous or smooth spathes, leaf-sheaths, and petioles. 
The variety is established upon some fruits, collected by Labillardière in Buru, 
which are figured by Turpin (l. c.) in the plate’ representing Sagus genuina 
Labillardière. 
Blume, Martius, and Miquel have supposed Sagus genuina Labill to correspond 
to Rumph's “Sagu duri rottang;" but this latter I have reduced to M. Rumphit 
var. ceramense, and I now consider the fruits of the Metroxylon collected by 
Labillardière in Buru, as representing a distinct variety, perhaps more distinct 
from M. Rumphit (or M. Sagus) than any other. 
Regarding these fruits, and the two plates representing Sagus genuina» in 
Turpin's Dictionary I have to remark :—. 
(1) The specimens, on which the artist based his representation of Sagus genuina 
in Turpin’s . Dictionary, were mixed, as I have been able to verify by actual 
inspection of the specimens of Metroxylon collected by Labillardière in Buru. and 
preserved in the Herbaria of Florence, Paris and de Candolle; in fact these speci- 
mens consist of spike-bearing branches, and of detached fruits, parts evidently 
belonging to two distinct varieties. In the Paris Herbarium these specimens are
