After 89, D. PEEciiA, insert — 



89/1. D. PANDUEiEEEUM, Hooh. f. ; stems elongate cylindric grooved, leaves 

 (on young stems only) lanceolate, racemes short 6-8-fld., dorsal sepal broadly pvate 

 obtuse, petals orbicular crenate, mentum many times longer than the broadly ovate 

 Bubaeate lateral sepals ,tip swollen, claw very long and slender, limb small deeply 

 constricted in the middle forming lateral auricle-like side lobes and an obeordate 

 midlobe, disk with a large transverse lamella between the side lobes. 



Pequ ; at Bangoon, Gilbert (Ic. in Serb. Calcuit.), 



Stems 2-3 ft., narrowed at the base ; interuodes l-lj by J in., nodes often 

 rooting ; sheaths membranous, white, young green and speckled. Leaves few, 

 1-1^ in., acuminate. Sacemes 1-2 in.; bracts small j pedicel with ovary J in.; 

 flowers 1 in. long ; sepals and petals green with streaks of red dots along the 

 numerous nerves ; mentum incurved, thickened towards the rounded tip, straight or 

 slightly curved, green streaked with red ; claw of lip 3-4 times as long as the dull 

 yellow limb, margins incurved above, below united to the wills of the mentum ; 

 anther stipitate on the top of the column, — Nearly allied to D. iropceoUflorum. 

 Also near 88, D. ionopus, E.f., but the flowers are not yellow with red blotches, nor 

 is the claw of the lip thick and keeled. Xhis will be figured in King's Annals of the 

 Calcutta Garden. 



Var. serpens. In the Calcutta Garden collection of drawings is one of a variety 

 ot panduriferum, or of a very closely allied species, marked as from Pcrak {^Kunstler), 

 with longer flexuous stems tuberous at the base, yellow sepals, and petals streaked 

 rather than dotted with red along the nerves, and a mentum as long but not thick- 

 ened towards the tip ; the limb of the lip is less constricted in the middle. This 

 may be Eeichenbacb's D. ionopus. 



89/2. D. TB0P(E0MPL0EXTM, HooTc. f. ; stem flexuous thickened upwards deeply 

 grooved, leaves linear-oblong, raceme slender 6.fld., dorsal sepal ovate acute, petals 

 very broad, mentum straight cylindric many times longer than the triangular-ovate 

 acute lateral sepals, lip with a very long slender claw and small panduriform limb 

 disk with a large semilunar callus. 



Pebae ; at Larut, Kunstler {Ic. in Serb. Oalcuti.). 



Stem a foot long, incurved, internodes f-l in., the thickest i in. diam. Zeaf 2^ 

 by f in., acute. Raceme 2 in., rachis pjnk ; bracts minute ; pedicel with ovary 

 ■| in., green ; flowers 1 in. long ; sepals and petals i-J in. long, dark red-purple ; 

 mentum | in., yellow-green, tip rounded ; limb of lip with a rounded retuse apiculate 

 tip. — ^A remarkable species, described from a drawing, which will be published in 

 King's Annals of the Calcutta Garden. According to a note by Mr. Brace which 

 accompanies the drawing, the sides of the claw of the lip adhere to the sides of the 

 mentum (as in pandur^erum and probably other species of Sect. Fedilonum). The 

 flowers very much resemble in form those of Tropaolum pentaphyllum, Lamk. 



P. 732. 91. D. BiEAEHTM ; after Wall. Cat. 2002, add (in part), for one of the 

 specimens is a var. of Appendicula bifaria. (See p. 83.) 



P. 737. 108. D. BPHEomoGiossiTM. D. stttfosum being the earlier name 

 should be adopted. 



P. 741. 124. D. PBNBtriitjM:. Dele Syn. B. Wardianum (see No. 127). D. 

 melananthum is considered to be a hybrid with D. Wardianum, 



\ P. 743. 130. D. Devonianum ; under Syns., after " not of Lodd." add, »or of 

 Boxb., or of Bot. Mag. 



131. D. DAiHOtrsiBANUM, must take the name of pULCHELLtrir, Uoxb. m Lindl. 

 Gen. 4- Sp. Orchid. 82 ; Fl. Ind. iii. 486, a species, which, misled by Lindley's 

 reference to it of JO. Devonianum, I had hitherto failed to recognize. Eeverting to 

 it for this supplement, I find nothing in Bozburgh's description and drawing to 

 distinguish it from DaUousieanum (also a native of Silhet) except the drawing of 

 the lip, which is too obeordate, and does not represent the villous tip, or the 

 pectinate lobes on the disk which are so conspicuous in the latter plant. On the 

 other hand, Roxburgh describes the lip as " beautifully marked, ciliate and ramenta. 

 ceous," characters that apply to DaUoiisieanum and to no other species at all like it.
