Dendrobium Vanover berg Mi, from the material I have examined, appears 
to be but slightly variable. The flowers of dried specimens indicate that 
the sepals and petals in a fresh state may have been whitish, the labellum 
purplish. The mentum may also show a purplish color in fresh specimens. 
D. Vanoverberghii is a member of the section or subgenus Pedilonum. 
6. DENDROBIUM (§ GRASTIDIUM) VERRUCULOSUM sp. nov. 
Caules elongati, teretes, ± 40 cm alti, verisimiliter plus quam 
50 cm alti, circiter 2 mm in diametro. Folia patentissima, 
lineari-lanceolata, inaequaliter obtuse 2-dentata, 7-9 cm longa, 
5-8 mm lata, basi rotundata, sensim longe acuminata, vaginae 
verruculosae internodiis aequilongae. Internodii circiter 1 cm 
longi. Inflorescentiae 2-florae. Flores mediocres, 2 cm lati. 
Racemi media e vagina foliorum orientes, brevissime. Pedi- 
cellus cum ovario plus minus 11 mm longus, gracilis. Sepala 
lateralia oblique triangula, elongata, acuminatissima, 9 mm longa, 
mentum 4 mm longum, valde obtusum, formantia. Sepalum 
dorsale oblongi-lanceolatum, acuminatissimum, superne paulo 
incrassatum, 9 mm longum. Petala linearia, acuminata, circiter 
8 mm longa, prope basim vix 1 mm lata. Labellum 3-lobatum, 
breviter unguiculatum, 8 mm longum, lineae per discum 3, ele- 
vatae, irregulariter dentatae; lobi laterales obtusi, lobus medius 
vix 4 mm longus, 2.5 mm latus, erosus, oblongi-lanceolatus, 
acuminatus, acutus. Gynostemium generis. 
Philippine Islands, W. S. Lyon H3, 1909. (Probably from Luzon.) 
Closely related to D. ornithoflorum Ames. From D. luzonense, a closely 
allied species it is easily separated by the three, elevated, irregularly 
dentate keels which are conspicuous on the middle lobe and which become 
confluent opposite the lateral lobes where they form a thickened ridge. 
The sheathing bases of the leaves in dried specimens are longitudinally 
nerved with minutely verruculose nerves. 
SARCOPODIUM Lindley 
SARCOPODIUM STELLA-SYLVAE Loher & Kranzlin in Fedde Report. 
7 (1909) 40. 
This interesting plant, which appears to be a diminutive form of 
Bar copodium acuminatum Rolfe, is a native of Luzon. In the Herbarium 
of the Bureau of Science there is a specimen which agrees well with the 
original description of Sarcopodium stella-silvae and which resembles closely 
the illustration in Kranzlin’s monograph of the Dendrobiinae in Engler’s 
Pflanzenreich. The leaves are longer than those described from the type, 
being, in the specimens before me, about 5 cm long by 2 cm broad. The 
flowers are about as large as those of D. acuminatum, white, with a yellow 
and brownish labellum.
