Desmogyne angustifolia, Knagg. 
‘Species affinis D. neriifoliae, King et Prain, a qua foliis 
lineari-lanceolatis longe acuminatis et calyce Jobato haud trun- 
cato facile distinguitur. 
: Frutex epiphyticus glaberrimus, ramis dependentibus gracil- 
ibus. Folia alterna; lamina 6-13 em. longa 0.25~-1.25 cm. lata, 
coriacea, lineari-lanceolata, apice longe attenuata, basi in 
petiolum gradatim angustata, margine integra valde revoluta, 
costa subtus prominente supra impressa; petiolus 0.25-1 cm. 
longus. Inflorescentia corymbosa floribus 2-8; pedunculi 2-6 
cm. longi; pedicelli 1.5-2.5 cm. longi sursum incrassati apice 
in cupulam 6-8 mm. altam expansi; bracteae triangulares acutae 
1 mm. longae. Calyx 3-4 mm. longus, 4 mm. latus, tubulosus, 
5-lobatus, lobis circ. 1 mm. longis acutis anguste triangularibus 
apice valde attenuatis basi circ. 1 mm. latis. Corolla 2-2.5 cm. 
longa, 3 mm. lata, tubulosa, recta 5-lobata, lobis brevibus 
anguste triangularibus circ. 2 mm. longis. Stamina 10, 
epigyna, libera, filamentis brevissimis circ. I mm. longis, 
antherarum elongatarum erectarum apicibus ad corollae os 
attingentibus. Ovarium s-loculare, stylo filiformi apice indis-

‘Burma :—Headwaters of the Irrawaddy, Nam Yin. Alt. 
2,000 ft. Cup, calyx and lower part of the perianth dull 
crimson, upper part of perianth pale green with red reticulations. 
‘The flowers apparently do not open. The anthers are at the 
bottom of the tube on a very short filament, and long appendages 
reaching to the apex of the tube. Epiphytic, hanging in long 
festoons from trees lining the river. At the base of the stem 
is a large woody swollen water-reservoir, from the other side 
of which grow the long roots.’ Coll. F. Kingdon Ward. No. 
5566. 3-12-22. 
This species differs from D. neriifolia, King et Prain, in 
having narrower strongly revolute leaves and in the distinctly 
*obed, not truncate, calyx. Moreover, the flowers are smaller
