Lofty herb. Leaves subsessile oblong or linear lanceolate rather varia- 

 ble, arachnoid-pilose on the back side, varying between subglabrous and 

 densely villous. Ligula bipartite to the base, lobes now very short, now, in 

 older parts, unto 15 mm. long, ovate, more or less tomentose. In young 

 leaves always very short. Spike on a very long peduncle (400 mm. to one 

 M), erect, at last more or less overhanging, with rounded mucronate scales ; 

 cylindric fusiform, obtuse or acute. Bracts much appressed, obovate or 

 lanceolate, rounded at the top or very acute, mucronate below the top 

 tomentose or quite glabrous. Flower 60 mm. long, pale yellow; labellum; 

 dark purple. Calyx spathaceous and much inflated above the middle, a little 

 longer than the short btacteole, 1/6 shorter than tube, acute. Lobes large 

 very acute, the lateral ones patent and projecting. Labellum broadly or 

 oblong-ovate, refuse or subentire. dark purple with yellow spots, Staminodes, 

 ovate, yellow, adnate, free for 1/2 of their length, patent, rounded or den- 

 ticulate-truncate, rarely acute. 



This species only known till now from mt Gedeh and from Borneo 

 (erroneously Sumatra in my former publication) has now been collected 

 at many places in West-Java and Nusa kembangan from 300 — 1600 M. and 

 proves to be most variable as to the shape of the leaves, labellum, and 

 pubescence. Farther east than the Kinderzee it has not been found. It has 

 not been found neither in Malacca nor in Sumatra. 



Common name in West-Java "belacatoa", sometimes "tongtak". The 

 latter name belonging more constantly to Z. inflexum and Z. neglectum. 



1 distinguish the following varieties: 



var. 1 genuina. Spike blunt rather broad, bracts with an obtuse or even 

 rounded rarely subacute top, mucronate, puberulous with a villousmargo. Lowest 

 bracts large. Labellum (n)iddle- lobe) as broad as tall (15 mm.); staminodes roun- 

 ded, siylodes 6 mm. long, subulate. Probably in all mountain forests of W.Java, 

 a tonientosa. Leafbackside and ligula densely villous, bracts tomentose.
