MERRILL AND MERRITT. 
cm long, 1.5 to 3 cm wide, the base acute, the apex shortly and usually 
rather sharply acuminate, somewhat shining when dry, the margins 
sometimes recurved; nerves about 9 on each side of the midrib, beneath 
prominent, anastomosing, the reticulations rather dense; stipules lan- 
ceolate, acuminate, deciduous,. 9 to 12 mm long. Inflorescence terminal, 
short, 2 to 4 cm long, the flowers crowded, subverticillate at the apices of 
the rachis and the few branches. Flowers white, sessile. Calyx narrowly 
funnel-shapped, about 4 mm long, the mouth often slightly oblique, 
slightly and irregularly ,5- or 6-toothed. Corolla about 6 mm long, 
the lobes 4, spreading or reflexed, ovate, obtuse, 4 mm long, 2.5 mm 
wide, the throat white-hairy. Anthers elliptic, 1 mm long. Style as 
long as the corolla, the arms 0.5 mm long. Fruit narrowly obovoid, 7 
to 8 mm long, 5 mm in diameter, narrowed at the base, somewhat 
wrinkled when dry, tipped with the cylindric, persistent, about 1.5 mm 
long calyx-tube. Seeds 3.5 mm long, 3 mm wide, subhemispherical, 
not at all ridged or striate on the back. 
In the mossy forest, altitude above 2,400 m, Merrill 8495 (type), McGregor

Apparently a distinct species and quite different from any of the previously 
described Philippine forms; it is well characterized by its prominently nerved 
leaves, rather dense and distinct reticulations, whorled sessile flowers and smooth, 
not ridged or grooved seeds. A closely allied form is represented by C. M. Z. 
16353, from the same altitude and habitat, the branchlets ferruginous-pubescent. 
PAEDER I A Linn. 
1. P. tomentosa Bl. Bijdr. (1826) 968. 
Stream depressions in the pine region, altitude about 1,500 m, G. M. Z. 16204, 
16215. 
Widely distributed 'in the Philippines at low and medium altitudes; India, 
Japan, and Malaya. 
NERTERA Banks & Soland. 
1. N. depressa Banks & Soland. ex Gaertn. Fruct. 1 (1788) 124, t. 26. 
In the mossy forest above an altitude of 2,400 m, G. M. Z. 16218, Merrill 6599'. 
This species is widely distributed in the Philippines, mostly at high altitudes, 
and has been found on Mount Paraga, Province of Abra, (Bur. Sci. 7065 Ramos), 
Mount Data, District of Lepanto ( Merrill 4524), various places in Benguet at 
higher altitudes ( Bur. Sci. 2796, 2863, 2498, 4372, 4453 M earns, Bur. Sci. 5444 
Ramos, Topping 77), Mount Banajao, Province of Tayabas (Whitford 937, Elmer 
9190, Bur. Sci. 6077, 6576 Robinson) , Mount Pinatubo, Province of Zambales, 
(Bur. Sci. 2609 Foxworthy) , Mount Haleon, Mindoro (For. Bur. 4459 Merritt, 
Merrill 5614), and Mount Apo, Mindanao, (Copeland 1078). It is somewhat 
variable in vegetative characters, but apparently a single species is represented. 
Whether or not it is the true Nertera depressa Banks & Solander, I am unable to 
determine. It may prove to be the same as N. nigricarpa Hayata, recently 
described from Mount Morrison, Formosa. It is reported from eastern Australia, 
Tasmania, New Zealand, South America, and apparently also Java, although 
Bentham expresses the opinion that the Javan form represents a distinct species.
