NOTES ON PHILIPPINE ORCHIDS, IV. 15 
alum swperius lanceolatum. Petala lineari-lanceolata. Label- 
lum lineari-oblongum, ad apicem bilobum. 
In leafage and in the bilobed tip of the labellum similar to 
Dendrobium aloifolium Reichb. f. Stems simple or branching, 
1 to 4 dm tall or even taller. Leaves distichous, extending along 
the stem from the base to the summit, gradually diminishing 
in size, from the point of insertion of the sheathing base to the 
tip 1 to 2 cm long (average somewhat exceeding 1.5 cm), free 
portion of the leaf lanceolate, acute, about 1 cm long from 
inner angle to tip. Inflorescence terminal, floriferous part of 
the stem up to 2 cm long. Pedicels arising from small heads 
of minute bracts. Pedicel and ovary 3 mm long. Lateral sepals 
3 mm long, oblong, acute. Upper sepal 2.75 mm long, lanceo- 
late. Petals linear-lanceolate, 3-nerved, obtuse or subacute, 2.25 
mm long, slightly less than 1 mm wide. Labellum 3 mm long, 
1 mm wide at base, linear-oblong, slightly dilated below the 
middle, above the middle contracted, the tip deeply retuse, or 
cleft, the lobes 1 mm long, obtuse. At the point where the lip 
is contracted, a transversely situated fleshy callus occurs. 
Mentum obtuse, about 2 mm long. Column 1 mm long. 
Basilan, W. I. Hutchinson, For. Bur. 3968, January 23, 1906. 
Dendrobium basilanense is nearly allied to D. aloifolium, from which it 
is to be distinguished by the linear-oblong labellum, scarcely, if at all, 
broader near the middle than at the tip. 
In his monograph of the Dendrobiinae ® Doctor Kranzlin cites D. Merrillii 
Ames Orch. 2: 181, as a synonym of D. aloifolium. I believe this is clearly 
the result of an error in judgment. D. Merrillii is unlike D. aloifolium in 
leafage and has an entire or obscurely retuse middle lobe of the labellum. 
With the original description of D. Merrillii mention was made of two 
collections, one Merrill 3357, and one Loher 6017. On the sheet of Loher’s 
specimen in my herbarium I find in A. A. Eaton’s handwriting “Not 
aloifolium." This note was made when Eaton and I were comparing the 
Philippine species of § Aporum with the specimens preserved at the British 
Museum of Natural History and at Kew. Doctor Kranzlin refers to Merrill 
3357 in the geographical notes under D. aloifolium and from the exclamation 
mark after the number it would seem that he had examined the type. Yet, 
he makes no revision in the description of D. aloifolium which accounts for 
the inclusion of material which has a three-lobed labellum with the apical 
lobe oblong, and inconspicuously, if at all, retuse at the tip. D. merrillii 
Ames is also given by Kranzlin ^ under his “Species Dendrobii imperfecte 
notae.” 
Dendrobium Brongniartii Kranzl. in Engl. Pflanzenreich 45 (1910) 210. 
This is a robust species of § Aporum. The flowers are de- 
scribed by collectors some as white, some as yellow, others as
