Victorian Plants. 419 



clasping, almost bract-like ; flowers rather large, two or 

 oftener few or several, somewhat brown-reddish ; lower 

 calyx-lobes pendent, generally transparent between the 

 reticular ventilation, from rather short-pointed to much 

 filamentous-elongated; labellum blunt, variously ciliolated 

 and at the anterior base turgidly swollen ; gynostemium- 

 appendages ciliolated, both its angles blunt or the upper 

 slightly pointed ; fruit somewhat turgid. P. rufa. 



Flowers always small, the calyx-lobes blunt. 



Dwarf; basal leaves from orbicular- to lanceolar-ovate, 

 rather short ; stem-leaves from few to several, approxima- 

 ted, clasping, almost bract-like ; flowers few or oftener 

 several or many in the spike ; bracts rather short ; lower 

 calyx-lobes connate to near the summit; labellum glabrous, 

 almost orbicular-ovate, its appendage anteriorely basal, 

 almost clubshaped, dark-green upwards ; gynostemium- 

 appendages truncate at the summit, blunt-lobed down- 

 ward ; fruit somewhat turgid. P. mutica. 



1806. Lower calyx-lobes diverging from the upper. 



Dwarf ; basal leaves rather short, from ovate to narrow - 

 lanceolar, crowded ; stem-leaves few, with exception of 

 the lowest almost bract-like ; flower large, its stalklet 

 usually much extending beyond the bract ; upper calyx- 

 lobe nearly straight and erect, short-pointed ; lower two 

 quite narrow, semi-connate ; labellum elongated, almost 

 filiform, long-exserted, much beset with yellow hairlets, 

 ending in a small purplish glabrous dilatation ; gynoste- 

 mium-appendages very narrowly protracted at the upper 

 angle ; fruit truncate-ovate. P. barbata.

1808. Labellum quite blunt. 



Never tall ; stem-leaves three or four, short, narrow-lanceolar, 

 much pointed and clasping, the largest towards the flower ; 

 basal leaves roundish-ovate, only occurring in the early 

 stage of the plant ; flower rather large, sometimes ante- 

 riorely slightly reddish ; bract similar to the stem-leaves ; 

 calyx-lobes ending in narrow elongations, the lower from 

 above their junction separated by a wide sinus, extending 

 far across the upper ; labellum very much longer than 

 broad, blunt, smooth ; appendages near the summit of the 

 gynostemium glabrous, acute upwards, obtuse downward ; 

 fruit rather slender. P. obtusa.
