5. C. brevilabre (lip short), F. v. M. Fragm. xi. 87. Stems elongated 

 clothed with the sheath of old leaves and sending out filiform roots. Leaves 

 from ovate to narrow-lanceolate, 2 to Sin. long, ^ to lin. broad, nervato-striate. 

 Eacemes 8 to 4in. long the peduncle somewhat short. Bracts deltoid about 1 

 line long. Pedicel with ovary about 3 lines. Sepals about 2 lines long slightly 

 falcate. Petals rather shorter than the sepals. Labellum fleshy, lateral lobes 

 •| line high, semi-orbicular. Middle lobe almost conical. Spur 3 lines long. 

 Column very short. 



Hab.: Mt. Dryander, E. Fitzalan. 



6. C. IVEacphersoni (after the Hon. J. A. Macpherson), F. Muell. Herb. ; 

 Benth. Fl. Austr. vi. 297. Stems short, covered with the very prominent bases 

 of the leaves. Leaves 4 to Gin. long and at least lin. broad, the veins not 

 prominent except the midrib, which forms an acute keel underneath. Spikes 

 rigid, not longer than the leaves, the flowers rather numerous sessile, reddish. 

 Sepals and petals rather thick, about 2^ lines long, all nearly equal. Column not 

 produced at the base. Labellum sessile, the spur oblong, obtuse, rather dilated 

 beyond the middle, IJ lines long, closed at the orifice by a large ovate plate close 

 under the column ; lamina short and broad, the middle lobe orbicular, about IJ 

 lines diameter, the lateral lobes shorter, falcate and narrow. Capsule oblong, 

 strongly ribbed. — Saccolahium Macphersonii, F. Muell. Fragm. vii. 96. 



Hab.: RoekinRham Bay, Dallachy; not uncommon in tropical scrubs. 



This has much the aspect of a small-flowered Sarcanthus, but the spur is not divided inside. 



7. C. Keffordii (after W. R. Kefford), Bail., in Rep. Ql. AccU. Soc, April, 

 1884. Stems elongated several feet, 8 or 4 lines thick, emitting strong, wiry 

 distant roots. Leaves coriaceous, 4 to 6in. long, about lin. broad, the apex very 

 obtuse, contracted at the base, the sheathing base strongly ribbed. Keel acute, 

 and 3 or 4 more or less prominent veins on either side. Racemes lateral, flexuose, 

 6 to 9in. long, 3 or 4 closely appressed obtuse bracts below the flowers. Flowers 

 16 to 20, yellowish-white on pedicels of about 5 lines. Outer segments or sepals, 

 and the inner ones or petals, about 4 lines long and 2 lines broad, somewhat 

 reflexed. Labellunr with pouch about the length of the other segments, slijpper- 

 shaped, the lateral lobes white, with a boss-like gland in the centre of each on 

 the inner side ; middle-lobe short ; appendage within the pouch hornlike, 

 glabrous. Column white, the wings joining in front and forming a prominent 

 beak. — Fitzg. Austr. Orch. ii. 21.

21. ORNITHOCHILUS, Wall. 

 (The lips of some species like the bill of a bird.) 



Sepals spreading, subequal, lateral obliquely obovate. Petals linear. Labellum 

 much larger than the sepals, clawed, lateral lobes subquadrate, middle lobe 

 clawed, inflexed lobulate and fimbricate, with a velvety flap over the mouth of 

 the short incurved spur, which is distant from the base. Column short, foot 

 often wanting, rostellum forcipate. Anther low 2-celled, pollen-masses 2, 

 subglobose or oblong, grooved, caudiele obcuneate. Epiphytes. Stem very 

 short, leaves few, broad, flat. Racemes lateral, flowers small. 



Species few, the Australian one endemic. 



1. O. Hillii (after Walter Hill), Benth. Journ. Linn. Soc. xviii. 834. Stems 

 rigid, flexuose, several inches long, covered with the prominent deeply striate 

 bases of the leaves. Leaves distichous, rigid, with prominent nerves, mostly 3 to 

 Sin. long and f to lin. broad. Racemes usually about the length of the leaf, the 

 flowers numerous and small on very short pedicels. Sepals and petals, oblong-
