SaCCOLABIUM (PoMATOCALl'i:) AliAtllXANTm;. J\II)L. 



This orc-hid is one of the group for which Dr. J. J. Smith 

 uses the name Pomatocalpe. A plant of it has been in the Botanic 

 (iardens for a loiitr time and flowered in April, 1916, and in May, 

 I'.il.S. ill both years the month of February was dry. 



The most curious thing about the flowers is that they face 

 u])wards — a rare occurrence in orchids. In the bud they are pack- 

 ed into a corymb. The flowers are white with a very faint lilac 

 tinge, and with a few deep lilac spots towards the base. The edge 

 of the septum which divides the spur from side to side is visible 

 from the front of the flower over the brim of the spur and between 

 the horns at the side, just as Dr. J. J. Smith figures it in Die 

 Ordiidcen von Java, flg. cdlviii, for Fomatocalpe latifoliuni. 



Flower of Saccolabium Arachnanthc, X viewed horizontal]y from the 

 side, and from above. 



The flowers fade pale green. They are pleasantly but not 

 strongly scented. 



The pollinating insects are unkno^^^^; but small bees are in- 

 dicated by the shape of the flowers as suitable visitors; such insects 

 would be expected to alight on the dorsal sepal and to approach the 

 lip between the obliquely ascending lateral petals in the direction 

 indicated by the arrow upon the figure. Such insects would 

 pollinate the flower after having sought in vain for honey in the 

 dry lower cliamber of the lip, by backing over the sexual organs, 

 and in the search for the narrow slit like aXwhich leads into the 

 smaller upper chamljer where tlie surface may be just moist.

In the Ciardencrs' Chronicle, vol. o5, 191-1, p. ?)2(}, Mr. T^idley 

 described Cj/pripcdiiini Prrcivae, as almost certainly a hybrid of 

 Ci/pripediuin niveiuit with another species such as 6'. E.viiJ. The 

 native collector, who got it, has brought from the same part of the 

 coast of the iSiamiese Malay States, namely the coast not far north 

 of the Kedah border, another plant, which, while not exactly ('. 

 Pereirae, appears equally to be a hybrid of C. niveum. The plant 

 in question fell into the hands of Mr. B. K. Saheb who grew it with 

 C. niveum and tlowcrcd it in dune, 1918.
