88 ORCHIDACE^ 



Epiphytic on trees in Mangrove swamp, Halsey, Culion Island, 

 December 25, 1902, K D. Merrill (no. 592). — Gimogon River, 

 Negros, January 5, 1904, E. B, Copeland (no. 136). (In Dr. 

 Perkins's Fragmenta Florae Philippince, Fasc. 1: 43, Merrill's 

 no. 592 is given by R. Schlechter as D. sinuatumj Lindl.) 



D. crumenatum, Sw., Schrad. Jour. Bot. 2 : 237 (1799) ; Kongl. 

 Vetens. Acad. Handl. 21 : 246 (1800) : " caule subramoso com- 

 pressiusculo basi tuberoso ; foHis ovato-lanceolatis ; spicis erectis, 

 floribus remotis alternis geminatis, processibus acuminatis. An- 

 grsecum crumenatum Rumph. amb. 6. 47. 2. E. Java Grondahl." 



Stems 3 dm. or more high, 6 mm. thick above, swollen below 

 and fusiform, the fusiform swelling 9 cm. long, about 12 mm. 

 thick. Stem branching above. Leaves ovate-lanceolate, emargi- 

 nate, 6-8 cm. long, 2.5-3 cm. wide, coriaceous, becoming smaller 

 above and then giving place to the flowers. Pedicels decurved 

 with sheathing bracts at the base. Lateral sepals about 2 cm. 

 long, triangular-lanceolate. Upper sepal and the petals narrower, 

 17 mm. long. Lip 23 mm. long, erect from the prolonged foot of 

 the column, then spreading, 3-lobed ; lateral lobes obtuse ; mid- 

 dle lobe oblong, rounded ; disc with several carunculate lamellae. 

 — The apical lobe of the labellum seems to be quite variable. In 

 the Botanical Register Lindley figures it acute. Plate 4013 in the 

 Botanical Magazine represents Dr. Copeland's material faithfully, 

 as does the illustration of the flowers in fig. 2, plate 47, Rumph. 

 Herb. Amb., which shows the lip to be emarginate, thus agreeing 

 with some of the Philippine specimens. The flowers are white 

 (sometimes pale purple) with yellow lamellae on the Hp. The swollen 

 pseudobulbous base of the plant, which is contracted above into 

 the slender elongated leafy stem, the white flowers borne on the 

 leafless extremity of the stem, and the conical spur formed by the 

 lip and lateral sepals seem to distinguish this species from its allies.
