filament which is narrowed upwards and passes on the back of the anther 

 into the narrower fleshy connective; in Euciircuma about in the middle, in 

 Paracurciima near the base of the anther. 



The anther consists of the fleshy broad connective, ovate when seen 

 from the back, horse-shoe shaped on the section, and including the style, 

 each arm bearing a flat linear theca. Below the place of affixion to the 

 filament the back-wall is prolonged on either side- to an awlshaped spur 

 with a thickened base, while the outer wall ends downward in a small 

 projecting tubercle. The top of the ovate or oblong dorsal portion of the 

 connective is sometimes quite blunt, sometimes it is prolonged into a small 

 lingula projecting between the two anther cells. This is mostly yellow and 

 of a glandulous tissue. The apex of the style with the stigma passing 

 between the two anthercells is in the bud enclosed between these and the 

 lingula, but in the open flower it passes beyond it and is protected by the 

 hood of the petal only. 



^ In C. aurantiaca the shape of the antlier is somewhat different. Here 

 the connective is also horse-shoe-shaped but the connecting portion on the 

 back is not ovate but linear and nearly as long as the thecae, the point of 

 affixion to the connective being near the base; upwards it continues behind 

 the top of the thecae and forms above these a small room, just large enough 

 to be filled out by the stigma. There are no spurs at the base but the 

 anther is here obliquely .truncate and the thecae continue on the lower 

 margin of it, bending backward with a right angle; the tubercle of the wall 

 is wanting. The anther is curved in the shape of a shallow C, concave on 

 the face. Compare PI. 11 fig. 28. 



In the shape of the stamen, as well as in nearly all other traits, 

 C. petiolata is intermediate between C. aurantiaca and the Eucurcuina-specles. 

 Here the affixion of the anther is near the base, as in C. aurantiaca, but 

 there are short curved spurs; and the thecae continue with right angles on 

 the lower margin of the anther, and over the foremost surface of the spurs. 

 The tubercle of the anter wall is present. The prolongation at the top of 

 the connective is much smaller than in the former and approaches in shape 

 the lingula of Eucurcuma, and the stigma is somewhat projected beyond it. 



The shape of the anther and of the spur is rather constant in each 

 species. Differences exist in the pubescence, in the lenght and width of the 

 thecae and of the lingula, the length of the dorsal part of the connective 

 and especially in the form and divergence of the spurs. Most of these are 

 of any use only in fresh material, e.g. the pubescence which is only conspicuous 

 in open flowers and the form of the spurs, which become difformed in 

 drying up. Only more considerable differences in the shape of the thecae 

 and of the appendage of the connective, can be recognized in herbarium 

 materials. But here only ripe buds are to be used, for in the decaying flower
