SCHLECHTER-—ORCHIDACEAE 109 
“ Plant of 9-15 inches. Flowers yellowish. On trunks of 
trees and humus-covered boulders in mixed forests on the eastern 
flank of the Tali Range. Lat. 25° 40’ N. Alt. 8-gooo it. 
July-August 1906.”’ G. Forrest. No. 4879. 
This remarkable plant at first sight has the appearance of a 
large flowered species of Pholidota, as the spur of the labellum is 
hidden between the sepals. The presence of a genus with a 
spurred labellum is most unexpected in the group Coelogyninae, 
as hitherto, with the exception of small concavities at the base 
of the labellum, nothing like it is known in this affinity. 
Microstylis yunnanensis, Schltr. Sp. nov. Plate lxxxiii. 
Terrestris, erecta I0-23 cm. alta; rhizomate abbreviato, 
bulbis ut videtur subterraneis, approximatis, oblique ovoideis, 
vaginis mox in fibros solutis circumdatis, usque ad 1°5 cm. longis, 
infra medium 0°7 cm. diametro ; foltis vulgo 2, interdum singulis, 
erecto-patentibus, petiolo scapum basi alte vaginantibus, lamina 
oblonga vel elliptica, obtusiuscula, utrinque glabra, 2-5-5 cm. 
longa, 1°5-2°5 cm. medio lata, petiolo lato usque ad 4 cm. longo ; 
scapo erecto, stricto, folia bene superante, pedunculo leviter 
angulato, glabro, racemo subdense multifloro, cylindraceo, usque 
ad Ir cm. longo, 1°6-1'°8 cm. diametiente ; bracteis erecto- 
patentibus lanceolatis acuminatis, ovario duplo-brevioribus ; 
floribus illis M. muscifera, Ridl. similibus sed multo majoribus, 
erecto-patentibus, glabris, sepalis lanceolatis longe acuminatis 
c. 0°5 cm. longis, lateralibus obliquis; petalis oblique lineari- 
lanceolatis, longe acuminatis, 0°3 cm. longis; labello e basi 
auriculato-cordata ovata, infra medium angustato, lanceolato, 
acuminato, 0°5 cm. longo, intus carinis 2 carnosulis e basi usque 
ad marginem infra medium labelli decurrentibus, nervis 3 medi- 
anis in basi labelli subincrassatis ; columna_ brevi crassiuscula, 
anthera ovata obtusa ; ovario clavato, glabro, pedicello incluso

“Plant of 3-9 inches. Flowers greenish - yellow, faintly 
fragrant. Mountain meadows on the eastern flank of the 
Lichiang Range. Lat. 27° 15’ N. Alt. 11-12,000 ft. July 
1906.” G. Forrest. No. 2627. 
Undoubtedly an ally of M. muscifera, Ridl., but easily dis- 
tinguished by the larger flowers with longer drawn out segments, 
and the form of the labellum. 
Oreorchis patens, Lindl. in Journ. Linn. Soc. iii (1859), 27. 
“Plant of 6-9 inches. Flowers, sepals and petals brownish, 
labellum yellowish - green, spotted reddish-brown, fragrant.
