43. I> albo-sansuineum, Li>,iU. in Part. Fl. Gard. ii. 93, t. 57 

 (rr/y/ inaccurate] ; stems subclavate erect, leaves linear-lanceolate obtuse 

 or subacute, racemes erect lateral or subterminal on the leafing stems > 

 bracts very small, flowers large cream-cold, with red bars on the very 

 base of the lip, sepals oblong obttise, petals twice as broad apicnlate, 

 mentum rounded, lip large broadly obovate expanded waved with a short 

 convolute base. Sot. Mag. t. 5130. 



TENASSERIM ; on the Attran River, Lobb. 



Stem 6-16 in., glabrous; iuternodes 1-1 J- in. by | in. diam., lower narrower. 

 Leaves 5-7 by 1 in. Raceme 3-4 in., stoat, erect; bracts sheathing; flowers 

 3 in. diam., slightly scented. The figure in Paxton's Magazine (copied in Fl. des 

 Serres vii. t. 721, and Jard. Pleur. t. 203) is, as' Lindley implies, a made up one, and 

 differs in toto from that in the Bot. Mag., having 2-uate lateral flowers on a very 

 stout leafless stem. Lindley, however, cites Lobb for the flowers being racemose, as 

 they really are. A very anomalous plant.

 angled toothed in front, midlobe short lobulate fimbriate retuse and with 

 pectinate filiform processes, disk with a thickened grooved ridge between the
