138 ORCHIDACEAE. 13. Galadenia. 



9. C. filamentosa {thread-like, referring to the perianth-segments), R. Br. Very 

 slender, slightly hairy, 15-30 cm. high. Leaf narrow-linear, 7-15 cm. long, only slightly 

 hairy. Flowers usually 1-3, uniformly crimson. Perianth -segments dilated in their 

 basal fourth, thereafter produced into long hairy filaments. Dorsal sepal erect, 

 incurved, about 5-2 cm. long ; lateral sepals spreading, about 5-7 cm. long ; petals 

 spreading rather shorter than the dorsal sepal. Labellum ovate or cordate, about 

 6 mm. long and 3 mm. wide, on a short claw ; erect against the column in its basal 

 half, with shortly serrate margins ; thereafter recurved, the tip entire, not very acute ; 

 lamina with calli in 2 closely set rows extending to about the bend, sometimes marked 

 with deeply crimson divergent veins on a lighter ground. Column about 7 mm. high, 

 with wide hatchet-shaped wings above, less widely winged below. Anther without a 

 point. 



Monarto South and Kangaroo Island ; also New South Wales ; Victoria ; Tasmania ; 

 ' and Western Australia. Sept. 



Var. tentaculata. Morphologically identical with the type but differing in coloration. 

 Flowers cream-colored with dark markings. Perianth-segments cream-colored with 

 . reddish-brown central stripe and reddish-brown tips. Labellum with conspicuous 

 reddish-brown divergent veins. — C. tentaculata, Tate, non Schlecht. 



■ So far as is known the type has only one station on the mainland ; the variety has not 

 been reported from Kangaroo Island, where the type is plentiful.

10. C. bicalliata (calli in 2 rows), Rogers. Small, slender, hairy, about 10 cm. high. 

 Leaf very hairy, linear-lanceolate, about 8 cm. long, 3-nerved. Flower solitary, cream- 

 colored, with red veinings, pedicel rather shorter than the ovary. Perianth-segments 

 similar, dilated in their basal parts, then suddenly contracted into rather coarse cylindrical 

 hairy caudae. Dorsal sepal about 2 cm. long, one-third of which is dilated, incurved 

 over the column ; the lateral sepals about 1-8 cm., one-half of which is dilated, spreading ; 

 petals subpatent, gradually contracted into caudae. Labellum cream-colored, about 

 7 mm. long and 5 mm. wide, ovate, on a short movable claw ; erect in lower part, then 

 recurved to a rather blunt apex ; margins very shortly and bluntly serrate except the 

 posterior one, which is entire ; lamina marked by conspicuous red divergent veins ; calli 

 of the golf-stick type, in 2 well-defined rows, extending to within 3 mm. of the extreme 

 tip. Column about 8 mm. long, erect, then incurved, widely winged in its upper third, 

 narrowly below. Anther without a point. 



Near Kingscote, Kangaroo Island. Sept. 



11. C. Menziesii (after Archd. Menzies, a surgeon-botanist), R. Br. (PI. 8, i.) Generally 

 rather slender, 0-20 cm. high, but sometimes much exceeding this. Leaf glabrous or almost 

 so, of variable shape and size, usually ovate-lanceolate or broadly oblong-lanceolate, 

 3-6 tin. long. Flowers 1-3, white and pink, occasionally entirely white. Dorsal sepal 

 reddish, very glandular-hairy on the back, spathulate-lanceolate, contracted gradually 

 towards the base, rather blunt, abruptly incurved over the anther, concave, about 11 mm. 

 long. Lateral sepals spreading, white, traversed by a pink stripe on lower surface, 

 crescentic, wide in middle, contracted towards both ends, same length as the dorsal one. 

 Petals (i., p.) reddish, very narrow-linear in lower half, clavate and closely glandular 

 above, erect, about 20 mm. long. Labellum (i., I ; figs. 1, 2) on a short claw, about 

 7 mm. long, including claw, white with conspicuous transverse pink markings, orbicular- 

 ovate, undivided, erect at base, tip white, blunt, recurved ; margins entire or nearly so ; 

 calli on very slender pedicels with large rounded heads, arranged in 2-4 rows, not ex- 

 tending to the tip. Column (figs. 3, 4.) about 7 mm. long, erect or slightly incurved, 

 with transverse pink striae ; widely winged throughout. Anther compressed laterally 

 like a fireman's helmet, shortly pointed. Pollinia 4, lamellate but departing in shape 

 from that prevailing in previous members of the genus, angular like a try-square.

12. C. latifolia (wide-leaved), R. Br. Moderately robust, hairy, 15-30 cm. high. Leaf 

 very hairy, oblong-lanceolate, 4-10 cm. long. Flowers moderately large, pink or white, 

 1-3. Perianth-segments lighter-colored on the outside, glandular-hairy, spreading with 

 exception of dorsal sepal. Dorsal sepal oblong-lanceolate, erect, not very acute, about 

 15 mm. long ; lateral sepals free or slightly adherent at extreme base, equal to. or slightly 

 longer and wider than the dorsal one, oblong-lanceolate. Petals elliptic -lanceolate ; 

 more contracted at the base, shorter and more acute than the other segments ; 12-13 mm. 

 long. Labellum pink or white, sessile ; 6-7 mm. long ; deeply 3-partite ; lateral lobes 

 and base erect clasping the column, the former oblong obtuse, margins entire ; middle 

 lobe recurved, broadly lanceolate, its margins with a few blunt linear teeth; calli of 

 lamina linear or clavate, arranged semicircularly at or near the bend, or in 2 converging
