OREOMYRRHIS BORNEENSIS MERR. 
branches which are short and densely crowded, and covered with the 
persistent dry sheathing basal parts of the petioles, the plant glabrous 
or subglabrous. Leaves long-petioled, the petioles glabrous, slender, 
up to 10 cm. in length, the margins of the basal sheathing parts some- 
what ciliate; lamina in outline oblong, 1.5 to 4 cm. long, 0.7 to 1.5 cm. 
wide, bi-tripinnately dissected, the segments small, rather rigid, ob- 
long, numerous, i to 2 mm. long, 0.3 to 0.5 mm. wide, their margins 
sometimes very obscurely ciliate, apices acute to apiculate-acuminate. 
Peduncles shorter then the petioles, reaching a maximum length of 
7 cm. in fruit, in anthesis not more than 3 cm. long and then much 
more pubescent than when in fruit, the hairs short, cinereous, never 
reflexed. Involucral bracts about 10, oblong-lanceolate, acuminate, 
somewhat pubescent, about 3 mm. long, 0.5 to 0.8 mm. wide. Flowers 
about 10, pinkish, short-pedicelled, much shorter than the bracts. 
Petals ovate to broadly elliptic-ovate, about 0.8 mm. long, the basal 
margins slightly ciliate. Fruits oblong, 3 to 4 mm. long, narrowed 
upward, acuminate, distinctly cinereous-hirsute with short hairs, the 
carpels distantly 5-ribbed, the pedicels very slightly or not at all 
elongated in fruit. Vittae as in other species of the genus, one under 
each furrow and two toward the commissure, the commissural side 
of the albumen merely slightly concave, not furrowed.

I have before me several New Zealand and Australian specimens of 
Oreomyrrhis representing as many different forms or varieties of 
Oreomyrrhis andicola Endl. as there are specimens. I cannot consider 
the Kinabalu specimen to be specifically identical with any of these 
forms, the several species described from Australia and from New 
Zealand having, by common consent, all been reduced to the South 
American 0. andicola Endl., thus giving us but a single species of the 
small genus in the Old World. The species above described distinctly 
approaches a New Zealand form from Awatere, distributed by H. 
H. Travers as Oreomyrrhis andicola Endl. forma tenuifolia. It differs 
radically from this form, however, in its very long petioles; in its 
peduncles being shorter than the petioles, the New Zealand form hav- 
ing the peduncles much longer than the leaves; in its very short pedicels 
and in its cinereous-hirsute, not glabrous fruits.
