ORCHIDACEM 73 



transversely, and containing a double pollen-mass, united at the 

 base by a granulated gland, each portion obovate, yellow." 



Pseudobulbs 5 cm. or more long. Leaf 14-30 cm. long. 

 Flowers distichous, about 7 mm. long. Capsule ellipsoidal. 



Mt. Mariveles, Prov. Bataan, Luzon, January, 1904, E. B. 

 Copeland. Although the specimens collected by Dr. Copeland 

 were in fruit, there seems to be no reason to doubt their identity. 



This species is figured in Part XII., plate 24, of Van Rhede's 

 Hortus Maldbaricus and described on page 47. I have given 

 Hooker's description, as it is the first under the correct combi- 

 nation, and as the original description is rather more lengthy 

 than useful.

A. WmTFORDii, Rolfe, sp. nov. '* Rhizomes stout, woody. Pseu- 

 dobulbs about ^ inch apart, ovoid-oblong, ^-^ hn. long, mono- 

 phyllous. Leaves petiolate, blade narrowly oblong-lanceolate, apic- 

 ulate, 2|-3 in. long, 3 lin. broad. Scape terminal, about 4 

 inches high, basal half very slender, and bearing a pair of ovate

 A. pumilum, Rolfe {Dendrocliilum p)umilum, Rchb., f.), which is 

 much larger in all its parts, and has flowers about four times as 

 large. The flowers are not in good condition, the lip being missing
