1344 LEAFLETS OF PHILIPPINE BoTANY [Vor. IV, ArT. 70 
Type specimen 12949, A. D. E. Elmer, Puerto Princesa 
(Mt. Pulgar), Palawan, April, 1911. 
Collected it in moist soil of loose moss covered rocks near 
a stream at 1500 feet or becoming dwarfed plants in dry com- 
pact soil on forested ridges at about the same altitude. 
In my first article on Rubiaceae page 22 of this publication, 
I keyed out O. mungos Linn. from the balance of our then known 
Philippine species by ‘“‘Mature infrutescence and leaves usually 
staining red while drying." At that time it was suggested to 
me that the specimens turned red through the red stained poi- 
soning liquid used. But all subsequent specimens of the above 
named species have also turned red. Furthermore, all the rest of 
our Philippine species in the herbarium have also been poisoned 
but without the red stain. These facts are verified in all herbaria 
having Ophiorrhiza collections. This new species also turns 
characteristically red while curing and certainly no stain- 
ing liquid has yet been applied. In this mount Pulgar specimen 
I found the process of turning red ‘while drying! exactly as I 
stated itin my key over five years ago. Apparently this same 
a pubescent and reddish tinged plant extends southwards to 
: Singapore. 
PAVETTA Linn. 
Pavetta palawanensis Elm. n. sp. 
A slender shrub; stem 2.5 em. thick, terete, 3 to 5 m. high, 
branehed from below the middle; wood sappy white, rather 
hard or tough, without odor and taste; bark caesius, more or less 
mottled, its hypodermis green; branches few, lax, the young 
ascendingly eurved twigs angular and avellaneus pubescent in 
the dry state. Leaves horizontally spreading, the abruptly acute 
or obtuse apex recurved, otherwise flat, coriaceous, much paler 
green on the finely pubescent nether ids, the upper glabrous 
. surface nearly black when dry, base cuneate, entire margins 
.  minutely involute, oblong or the smaller ones subelliptie, 17.5 
. . em. long excluding the stalk, 6.5 em. wide across the middle or 
a trifle above it; midvein rather prominent beneath especially 
toward me base, the e to 7 main pairs of nerves ascendingly
