2. Lip bare/ 1/ saccate below, tapering and its sides involute above ; anther ovate,

 above the stigma into a conspicuous tapering awl-shaped gland-bearing beak. 



3. G. Menziesii, Lindl. Leaves ovate-oblong, acute (2-3' long), less 

 white-reticulated than the preceding, some uot at all so ; scape 9-12' high ; 

 flowers rather numerous in a looser often 1-sided spike ; flower-buds less pu-

11. E P I P A C T I S, Haller. 



Sepals and petals nearly equal, spreading. Lip free, deeply concave at base, 

 narrowly constricted and somewhat jointed in the middle, the upper portiou 

 dilated and petaloid. Column short, erect. Anther sessile behind the broad 

 truncate stigma, on a slender-jointed base ; pollen-masses coarsely granular, 

 becoming attached to the gland capping the small rounded beak of the stigma. 

 Stem leafy, with racemed flowers, conspicuous bracts, and ovaries reflexed

12. A RE THUS A, Gronov. 



Flower ringent ; the lanceolate sepals and petals nearly alike, united at base,

 toward the summit; very slightly gibbous at base. Column adherent to the 

 lip below, petal-like, dilated at the apex. Anther lid-like, terminal, of 2 ap- 

 proximate cells; pollen-masses powdery -granular, 2 in each cell. Beautiful 

 low herbs, consisting of a sheathed scape from a globular solid bulb, termi- 

 nated usually by a single large rose-purple flower. Leaf solitary, linear, nerved, 

 hidden in the sheaths of the scape, protruding after flowering. (Dedicated to

13. CALOPOGON, E. Br. 



Flower with the ovary or stalk not twisting, therefore presenting its lip on

 stalk, dilated at the summit, strongly bearded along the upper side. Column
