1. Xi. nutans (nodding), Lindl. in Journ. Linn. Soc. i. 177; Benth. Fl. 

 Austr. vi. 308. "Maapa, Barron River, E. Coideij. Stem ascending from a 

 thick rhizome, tj to Din. high, with 2 or 3 empty scarious bracts besides those 

 which subtend the pedicels, all ovate-lanceolate, acute, 3 or 4 lines long. Flowers 

 white, on short pedicels in a raceme occupying the greater part of the plant. 

 Dorsal sepal and petals lanceolate, nearly 4 lines long, very thin, connivent, 

 lateral sepals narrower, Labellum sessile on a broad base enclosing the column, 

 as long as the sepals, broadly ovate and very concave, entire, the spur about 

 1 line long, the disk with 2 obscure rows of papillae along the centre. Appendage 

 at the end of the anther as large as the anther itself. — Oalera nutans, Blume,

49. HABENARIA, E. Br. 



(From the long strap-like spur resembling a rein.) 



Dorsal sepal erect, very concave ; lateral sepals free, connivent or spreading ; 

 petals entire or bipartite, usually connivent under the dorsal sepal. Labellum 

 3-lobed or rarely entire, with a spur or pouch at the base. Column very short, 

 with 2 anterior linear-clavate processes lying on or partially adnate to the base of 

 the labellum. Anther erect, with a broad connective and marginal cells, but the 

 connective usually so short that the erect diverging cells appear disconnected. 

 Pollen granular in 2 masses in each cell, each pair with a caudicle attached to a 

 gland or an appendage of the stigma opposite to the cell, and more or less 

 confluent with it. — Terrestrial herbs, with underground usually ovoid tubers. 

 Leaves alternate on the stem or collected near the base. Flowers several or 

 many in a terminal spike. 



A large genus dispersed over the warmer and temperate regions of both the New and the Old 

 World. 



Lateral lobes of the labellum long and very narrow-linear like the middle 

 lobe. 



Leaves narrow-oblong. Spur of the labellum above lin. long 1. H. elongata. 



Leaves linear. Spur of the labellum under Jin. long 2. H. graminea. 



Lateral lobes of the labellum filiform, lin. long ; middle lobe shorter. Spur 



IJin. long 3. H. Millan. 



Lateral lobes of the labellum very short and broad or quite obsolete, rarely 



shortly acuminate ; middle lobe oblong or broadly linear. Spur shorter 



than the sepals 4. H. xanthantha, 



1. H. elongata (elongate), R. Br. Prod. 313 ; Benth. Fl. Austr. vi. 394. 

 A rather stout species, above 1ft. high. Leaves oblong 2 to 4in. long. Spike- 

 rather dense. Dorsal sepal ovate, obtuse, 2 to 2J lines long ; petals about as 

 long, broadly falcate ; lateral sepals rather longer, adnate at the base to the sidea 

 of the spur. Labellum lobes very narrow-linear, the middle one above |^in. long, 

 the lateral ones rather shorter ; the spur at least IJin. long, thickened beyond 

 the middle. Anterior processes of the column clavate and cristate. — Lindl. Gen., 

 and Sp. Orch. 317 ; F. v. M. Fragm. vii. 15 ; Reichb. f. Beitr. 6.

2. H. graminea (grass-like), Lindl. Gen. and Sp. Orch. 318; Benth. Fl. 

 Austr. vi. 394. Stems slender, under 1ft. high. Leaves at the base of the stem- 

 linear or linear-lanceolate, acute, under Sin. long. Spike slender, short or long, 

 with short narrow bracts. Dorsal sepal in the typical form 2J lines long^ 

 lanceolate, concave ; petals as long, slightly falcate ; lateral sepals rather longer^
