photo image.
Rhizome long, creeping, 2-3 mm in thickness, covered by brown
cataphylls. Root fibrous, branching, flexuous, from lower part of pseudobulb. Pseudobulb
ovoid-narrower ovoid, 1.7-3.5 x 0.6-1 cm, placed 2-5.2 cm apart on
rhizome. Leaves 2 on each pseudobulb, linear, acute, shallowly obliquely bilobes,
5.9-13.4 cm x 0.65-0.95 cm, 3 second major nerves on each side of the midrib.
Inflorescence
from top of pseudobulb, shorter than the leaf, racemose; peduncle
thin, c.2.2-3.4 cm, rachis c.2.1 cm, brings about 3 flowers. Flower with red green petal on outside and yellow inside, dorsal sepal elliptic to slightly lanceolate, 1.7
x 0.65 cm, obtuse, 7 nerved, lateral sepal ovate to lanceolate, but wider at obliquely base, 1.7 x 0.75 cm, obtuse, petal elliptic linear, 1.8 x 0.4 cm, obtuse;
labellum trilobes, 1.38 x 1.12 cm when spread out, side lobes incurved, 1.13 cm
long, mid-lobe smaller, with three short fleshy ribs; column 0.9 cm, with wing on
both side, column foot about 0.59 cm.
Distribution : Near Lake Toba, North Sumatra.
Habita t: high elevation from 1,200 -1,500 m asl, flowering time: September.
Note: this species has linear leaf which seems similar to E. triflorum but acute
and the inflorescence shorter. Observation based on single specimen and

photograph of type from Oakes Ames Herbarium. Previously this species known as D. exilifolium. Carr named this species as Epigeneium verruciferum var.
pauciflorum. Comber probably missed the publication by Garay and Romero 1999 which has been transferred Dendrobium exilifolium to E. exilifolium and
proposed the same new combination name in 2001. Flower description was partly based on publication.
