Pseudobulbs 1-2 in., densely crowded. Leaves 3-6 in., erect. Scape -1 in., 

 clothed with distichous lanceolate membranous sheaths ; bracts persistent ; flowers 

 \\ hite or flesh-cold. ; sepals 1 in. ; lip with 3-7 orange spots ; column rather dilated 

 in the middle.

Pseudobulbs $ in., hardly thicker than the petiole; sheaths ovate, acute ; roots 

 very long, very thick, clothed with a loose inflated epidermis. Leaf 1-4 by -$ in., 

 erect, rigid, often purplish, margins recurved when dry. Scape 3-4 in., sheaths 

 few, minute ; bracts minute, rounded ; flowers nearly white ; pedicel with ovary 

 in.; sepals - in., erecto-patent, linear-oblong, obtuse, 3-uerved; petals linear- 

 spathulate, obtuse, 1-nerved ; lip sessile, erect, spathulate base and crenulate tip 

 saccate, disk quite smooth ; column erect, narrowly winged, tip dilated with toothed 

 sides; anther imperfectly 4-celled, persistent, purple ; pollinia 4, free, 2 larger sub - 

 pyrifcrm, 2 smaller angular. Capsule % in., narrowly oblong, 6-ribbed. I have 

 long puzzled over this curious little plant, for which I had proposed the generic name 

 Adrorhizon, in allusion to its remarkable roots, but await more specimens before 

 establishing it. From Dendrobium it differs in habit, in the long column without a 

 foot, and in the pollen ; and it is more near Cwlogyne or Panisea. 



SPECIES UNKNOWN TO ME. 



C. BRACHYPTEKA, Reichb.f. in Gard. Chron. 1881, ii. 6; pseudobulb a span 

 high tetragouous, leaves not Been, raceme several-fid., bracts equalling the ovary 

 persistent, sepals triangular ligulate acute light parrot-green, lateral keeled in the 

 middle, petals filiform, lip white with a brown stain, side lobes semi-ovate short 

 triangular in front, midlobe oblong acute undulate, keels 3 all warted in front, column 

 hooded and retuse at the top, hood creuulate. Flowers like G. lentiginosa. 

 (Possibly C. Parishiava, J. D. H.) 



C. CAULEfcCJ NS, Giijf'. JKotul. iii. 282, from maritime marshes at Pulo Bisar, 



Malacca, cannot be a L&logyne, but may be allied to Bromheadia. There are in 



Herb. Lindley fragments fiom Griffith so named, consisting of the rachis of a 



raceme, which agrees with Griffith's description, and of leaves of what I take to be 



of another plant.
