NEW ZEALAND SPECIES OF OOLOBANTHUS, 173 



truncata ovatis, petalis late orbicular!- ovatis obtusis ; labelli alis 

 vix prominentibns, sacco basali magno conico a calcare crasso 

 antice curvato terminato, lobo oblongo convexo, disco crista 

 mediana trifida instructo. 



Hab. Euwenzori (eastern side). On granite, 5300 ft., April 

 (greater rains), 1894, No. 7552. 



The slender floweriHg-stem (2i-3 ft. long) bears on its lower 

 nodes subscarious bracts with edges united for two-thirds their 

 length, and acute or acuminate apex; they are generally marked 

 with small dark spots, and are much shorter tban the internodes, 

 being only 1^-2 in. long. The acute flowering bracts are nearly 

 i in. long below, becoming shorter above. The dorsal sepal is 

 8i lines by 2^, the lateral ones are 4 lines by 3, and the broad 

 petals 6 lines long by 7i broad. The rounded scarcely projecting 

 wings of the lip are attached to the sides of the short tliick column, 

 and form an upward coutinuation of the large basal sac, of which 

 the blunt spur (2 lines long) is a terminal process; the latter has a 

 slight forward curve. The short terminal lobe (4 by 2| lines) 

 bears a large median crest, as described for L. saccatus, rising 1 line 

 above the disc. The two roundish pollinia show an indication of 

 further division, and are connected with the orbicular gland by a 

 short band (^ line long). The roundish anther is bluntly apiculate. 



Differs from the closely allied L. saccatus in its rather broader 

 bracts, shorter and proportionately broader sepals, smaller petals, 

 smaller oblong median lobe of lip, and thicker spur. Compared 

 with L. mUanjianus, another close ally, it has shorter broader sepals, 

 which are not aristulate, broader petals, a smaller median lobe to 

 the lip, and broader flowering bracts.
