Schismatoglottis silamensis A.Hay

Material examined. MALAYSIA – Tawau • Lahad Datu, Sapagaya VJR, Ultramafic , near rocky stream; 16 February 2012; 04°58′13″N, 118°05′12″E; 249 m elev.; Suzana S. et al. SAN 151427 ( SAN) .

Identification. Schismatoglottis silamensis is allied to S. calyptrata , S. motleyana , S. trivittata and S. trifasciata —variable species which tend to approach each other at the extremes of their variation. In this widespread alliance, S. silamensis is distinguished by the short interpistillar staminodes occurring in very large numbers in the female zone, the rather well-defined sterile interstice composed of abortive pistils and anthers, and its coriaceous leaves which have rather unusual variegation in three shades of green. It represents a local endemic segregate on ultramafic substrate ( Hay and Yuzammi 2000). Distribution and ecology. Endemic to Sabah. On rocks on (dry) stream bank in rather dry mixed lower montane forest on ultramafic substrate at ca. 500 m elev.
