224 ROBINSON. 
L 
2 lanceolate bracteoles 1.2 to 1.5 mm long, acute or acuminate at the 
apex: calyx in all 2.2 to 2.5 mm long, sometimes the tube but more 
often the lobes slightly the longer, the lobes 4, ovate, acuminate; corolla 
-white, the tube about 16 mm long, less than 1 mm in diameter at the 
base, nearly 1.4 mm in diameter at the base of the lobes, the latter 4, 
broadly lanceolate, acute, 7 mm long, 3 mm wide at the base, revoliite; 
filaments stout, 2.5 mm long; anthers 5.5. mm long, linear, the cells 
produced separately at the base for 2 mm below their insertion; style 
2 cm long, the stigmatic arms about 2 mm long: fruit red, subglobose, 
7 mm long in addition to the subpersistent calyx-lobes, 8 to 9 mm in 
diameter, 2-celled, each cell with 1 plano-convex seed about 5.5 mm 
long, peltately attached, or one cell sometimes aborting. 
A bush, its vegetative parts entirely glabrous, the ultimate branches 
quadrangular, dark-colored, the next older paler: leaves with grooved 
petioles 4 to 8 mm long, the submenibranaceous lamina lanceolate or 
oblong-lanceolate, 14 to 23 cm long, 4 to 7 cm wide, the base rounded 
or somewhat abruptly narrowed, very shortly acutely acuminate, the 
apex fonning an obtuse but at least sometimes mucronate acumen 1 
to 1.5 cm long; primary veins on each side of the midrib 18 to 25, 
slightly projecting or immersed, even on the same leaves, nearly straight 
or toward the margin well arched. 
roLiLLO, Bur, 8cl 10219 McGregor (type). Luzon, Province of Albay, Cuming 
896, the specimen here rather fni^uientury and apparently with fewer leaf-veins, 
but otherwise veiy similar. Allied to L Hngstoni Hook, f., but distinguished 
by the leaf-bases, venation, shorter corolla, and otherwise. 
Lasianthus copelandii Elmer Leafl. Philip. Bot. 1 {1900) 10. 
Represented by 9187; other distribution La-una, Negros, Mindoro, Mindanao. 
Myrmecodia s;p. 
A sterile specimen, 1022/,, is well matched by ^Vhitford 817, Tin-noan River, 
Tayabas, in a similar condition. 
Nauclea media Hav. in Journ. Linn. Soc. Bot. 33 (1897) 56. 
Represented by 9119, 10215; other distribution Rizal, Tayabas, Albay, Bataan, 
and Mindoro. 
Ophiorrhiza involucrata Elmer Leafl. Philip. Bot. 1 (1908) 251, 
Rather fre(iuent on Polillo, 6833; other distribution Tayabas. 
Ophiorrhiza mungos Linn. Sp. PI. (1753) loO. 
Represented by 9233; other distriI)ution Batanes, Babuyanes, Isabela, Ben- 
guet, Tayabas, Laguna, Mindanao, Java, Sumatra, Malay Peninsula, India, 
Ceylon. 
Psychotria banahaensis Elmer Leafl. Philip. Bot. 1 (1906) 26. 
AVell matched by 68^2; known also from Tayabas and Negroa, with closely 
allied forms in other provinces. Very similar, also, are three Polillo collections, 
6835, 10212, 1077o, but the venation of the broader leaves is coarser j all are 
fruiting, and when flowering material is secured, they may prove to belong to 
an undeHcrii)ed species.
