HABITAT.—South Borneo at Ban jar massing, discovered by J. Motlsi/ in lSo7-o8,
(No. 1103 in Herb. Kew.). Malayan name " Rotang Djernang laki". Motley in his
field-notes writes that " t h e fiotang is coarse and brittle, and of no value, but it yields
a small quantity of the best quality of the drug called ' Dragon's blood' extracted by
shaking together the unripe fruits ia bamboos; the inferior quality by boiling
the residue and evaporating the extract." Tlie name " R. Djernang " is applied by the
Malays to any species of Daemonorops yielding Dragon's blood, and the adjectivo
" l a k i " , %vhich means " m a l e " , would point to the excellency of the quality produced,
as it is their custom to distinguish with the name of " l a k i " the best woids,
fruits, or similar products, amongst those of the same nature.
OBSERVATiOiis.—D, Motleyi is a very near ally of D. didymophyllus, but diSevs from
it not only in the narrower female spadix, but especially in the more elongate and
less concave spathes, of which the outermost entirely envelopes the inner spathes
before the anthesis, and probably also in the fruit, which is larger aod has a greater
secretion of resin. There would appear to (belong D. Motleyi, or to a transitional form
between this and D. didymophyllus, a Daemonorops collected by Ridley at Puak i
(Borneo), in September 1905 (No, 12408 in Herb. Kew.), of which another s
preserved in Herb. Hort, Bot. Bogor., coming from Siutang in Dutch W. Borneo. Ridley's
specimen has the leaflets elongate lanceolate-elliptical, in pairs as in D. didymophylitis,
but witii occasionally a solitary one interposed, 28-32 cm. long, 3-3-o em. broad;
t h e quite mature fruit is 25-26 mm. long, and 20-21 mm. broad, and is slightly
covered with red resin; the seed is ovoid, slightly flattened, 16-17 mm. long,
13 mm. broad, 12 mm. thick. The fruit therefore difiers from that of D. didymophyllus
in being larger and more ovoid; further the seed ia not sub-globular, but ovoid
and somewhat flatteued.
The specimens from Sintang have the leaflets 30-36 cm. long, 3 - i em. broad in
pairs with occasionally a solitary one interposed; the male spadix is very narrow,
about 20 em. in length; the female spadix has the panicle 18 cm. long, and a
pedicellar flattened part which is rather strongly armed on the edges as ia the type
specimens of D. Motleyi. I have not seen'an entire fruit, but the scales are resiniforous •
the seed is ovoid, obtusely conical at" the upper end, very slightly |flaitoned, 15 mm.
long, 11 mm. broad.
D. didymophyllus] BECOAIU. THE SPECIES OF DAEMOIFOKOPS. JGS
The specimens now mentioned being both very incomplete and especially wanting
in the spathes, do not allow of a rigorous comparison either with D. didymophyllus
or with D. MoUeyi. In conclusion, from what I can judge by the material 1 have
exammed, D. Moileyi is only a geographical form of D. didymophyllus.
