6. Corolla and staminal-apparatus. There is always an elongate slender 

 common tube widened a little above but never so much as to form a dis- 

 tinct faux, and a short two lipped limb, which alone projects above the 

 bracts, and has more or less the shape of a snake's head or a duck's 

 beak. The upper end of the tube is often dorsally compressed and its 

 mouth (called „faux" by König l e. 6Q, 70) is a rather narrow transverse 

 split. After the anthesis, which lasts 24 hours, the limb which at first is 

 erect or almost horizontal is elevated by the rapid lengthening of the tube 

 and soon is found hanging alongside the spike, without at first being much 

 changed in shape. The limb consists of the dorsal petal (=segment=iobe), 

 which is oblong or oblong-ovate with a rounded somewhat cucuilate top 

 and more or less incurved margins and by itself forms the upper lip, and 

 the lateral petals, shorter and narrower than the dorsal one which are in 

 most species connate at their base and adnate to the base of the labellum 

 in the same way as is seen in the genus Zingiber. 



in most species the petals are patent and appressed to the underside 

 of the iabellum, a little projecting sideways near the top of this and forming 

 together with it the lower lip. In H. elongata they are ascending and 

 their free parts are placed sideways between the upper and lower lip 

 of the coroll. 



The labellum, which with the lateral petals forms the lower lip of the 

 coroll is in the majority of the species about as long as the upperlip or 

 a little longer, and placed just opposite it. It is what may be called 

 „slipper-shaped" (GRIFFITH p. 433) and consists of a middle part,— broadly 

 linear with a rounded apex and upcurved edges, rather stiff, and flat, hairy 

 at the inner surface,--and two semilunate sidelobes or auricles of a more 

 subtle petaloid structure at the lower part. Being explained, the lip has 

 a more or less hastate or ovate shape. In the young flowers the stamen 

 is applicated to and embedded in the concavity of the lip and its sidelobes 

 are inflexed or convolute and cover the backside of the stamen, in the open 

 flower they are suberect. In a few species H. elongata, H. mollis, H. alli- 

 acea, the lip is a little longer than the petals and the projecting tip is more 

 or less ascending in their upper half, only the base being appressed to the 

 labellum. In many species the sidelobes of the labellum are short not broad 

 enough to cover the back of the stamen, only protecting it sideways. 

 Here belong H. leonurus, H. lycostoma and many other species. In H. 

 villosa the structure of the lip and stamen is different from all other species. 

 There are no sidelobes to the labellum, and the middle lobe has a very 

 thick fleshy rib bifurcate at the base. The stamen is appressed to the lip as 

 in the other species but instead of being embedded in the cavity of the 

 lip, the filament is broader than the lip and covers it. 



In H. cyathifera and H. rubra the middle part of the lip is very short, 

 not or only a little projecting beyond the large sidelobes. Explained it is
