ORCHIDACEtE 



sagittate ; limb about 1.6 mm. long, 1.8 mm. broad, entire, rounded 

 to an obtuse or subacute apex, provided in the middle with a 

 pair of short longitudinal dark keels and nearer the base, in the 

 center, with a forward pointing tubercle; auricles 1—1.5 mm. 

 long, deltoid-lanceolate, with rounded apices. Column about 

 1.5 mm. long, concave on the anterior surface, angled posteriorly, 

 with a prominent papillose decurved tubercle at the base. 



The flowers show considerable range in size of perianth parts ; 

 the measurements given are of one of the larger flowers. In habit 

 this plant resembles Malaxis kinabaluensis (Rolfe) A. & S., but 

 the flower is different. 31.Burbidgei (Reichb. f ) O. K. has longer 

 leaves, shorter scapes, acute sepals and petals, and smaller lip 

 auricles. M. moluccana var. sagittata (J. J. Sm.) A. & S. is sim- 

 ilar, but has much larger racemes, broader petals, and a differ- 

 ent lip callus. M.incurva (J. J. Sm.) A. & S., while nearly related, 

 is larger especially as regards the flowers and lip auricles. This 

 is a much smaller species than M. tubulosa (J. J. Sm. ) Ames, 

 with orange instead of greenish-yellow flowers. From M. uncata 

 Ames, M. midtiflora differs in the absence of the long pedicels 

 and in the peculiar lip calli. (Plate 88.)
