414 Key to the System of 



from ovate- to narrow-lanceolar, pointed, much narrowed 

 towards the base, about twice as long as the petals, white 

 or slightly pink ; upper calyx-lobe and petals somewhat 

 red ; gynostemium narrow ; fruit slender. 



E. autuninalis. 



Labellum semiorbicular - cuneate, nearly flat, con- 

 spicuously fringed. 



Never tall, always very slender ; basal leaf lanceolar-ovate, 

 not rarely accompanied by a second ; stem-leaf distant, 

 elliptic -lanceolar, somewhat or considerably shorter ; 

 flowers rather small, one or less commonly two ; lower 

 lobes of the calyx narrowly elliptic-lanceolar, reddish, 

 about as long as the petals ; gynostemium narrow ; fruit 

 rather slender. Figure 113. E. finibriatus. 



CALADENIA. 



1791. Paired petals erect, longer than the calyx-lobes and 



much narrower. 



Never tall, slightly beset with hair lets ; basal leaf almost 

 glabrous, from broad-lanceolar to nearly ovate, usually 

 much shorter than the stem ; upper leaf bract-like ; 

 flowers one or two, the lower if present on a rather long 

 stalklet ; bracts conspicuous ; calyx-lobes mostly pale- 

 reddish ; paired petals almost linear, dark-red ; labellum 

 transversely striped, its glandules yellow, its middle lobe 

 upwards much narrowed and recurved ; fruit somewhat 

 turgid. C. Menziesii. 



Paired petals spreading and similar to the calyx- 

 lobes ... 1792 



1792. Calyx-lobes as well as the paired petals much 



narrowed upwards and thus conspicuously elongated. 



Often somewhat tall, but slender, always conspicuously 

 beset with soft spreading glandule -bearing hairlets ; 

 basal leaf from linear- to elongate-lanceolar ; stem-leaf 

 diminutive ; bracts conspicuous ; flowers large, one or 

 two, seldom more, almost white or variously reddish or 

 somewhat greenish or pale-yellowish, except the calyx- 

 tube ; labellum broad, variously fringed or denticulated 

 and callous-glandular, the middle lobe often more deeply 

 colored ; glandules variable in copiousness, arrangement, 

 shape and color, but mostly seriated ; gynostemium 

 upwards dilated; fruit somewhat turgid. "Spider- 

 Orchid." C. Fatersoni. 



Calyx-lobes slightly narrowed upwards 1793
