linear, not quite 2 lines long, the lateral ones adnata to the short basal projection 

 of the column, falcate as well as the petals, the dorsal one rather long and incurved, 

 all dotted with red. Labellum nearly as long as the sepals, the basal pouch 

 short and broad without any internal appendage, the lamina concave or embracing 

 the column, about as broad as long, truncate, almost without a middle lobe, the 

 angles (or lateral lobes) shortly acuminate and somewhat incurved, the disk with 

 an erect conical tooth or callosity immediately above the pouch but not reflexed 

 into it. — Saccolabium HilUi, F. v. M. Fragm. i. 192 ; Benth. Fl. Austr. vi. 298. 

 Hab.: Common on trees in the southern scrubs. 



22. TiENIOPHYLLUM, Blume. 



(Leaves of some species linear, ribbon-like.) 



Sepals and petals nearly equal, erect or connivent, connate at the base. 

 Labellum adnate to the column at the base and produced into a short spur or 

 pouch, entire or shortly 2-lobed. Column very short, erect, with 2 teeth in front. 

 Anther terminal, lid-like. Pollen-masses 4 in 2 pairs, with a short slender 

 caudicle. Gland minute. — Epiphytical herbs, almost stemless and leafless or 

 with a tuft of linear leaves. Flowers minute, in small slender racemes. 



The genus has but few species and besides Australia is met with in India, Malaya and the 

 Pacific Islands ; the Australian species is probably endemic. 



1. T. IVEuelleri (after Baron Mueller), Lindl. Herb. ; Benth. Fl. Austr. vi. 

 291. Stems leafless, scarcely above \ line long, emitting long linear wavy roots, 

 and 2 or 3 filiform scapes of about ^in. Bracts minute. Flowers 2 or 3 on 

 exceedingly short pedicels, and the whole flower under 1 line long. Sepals and 

 petals united to about the middle, the petals rather narrower than the sepals. 

 Xiabellum linear, as long as the sepals and shortly 2-lobed at the end, with a 

 minute tooth between the lobes, the basal pouch or spur obtuse, about J line long.

Hab.: On trees southern localities. 



28. GALEOLA, Lour. 



(With a small helmet.) 

 {Erythrorohis, Blume ; Ledgeria, F. v. M.) 

 Sepals and petals nearly equal in length, connivent or open, the dorsal sepal 

 incurved, the petals narrower. Labellum, sessile, broad, incurved round the 

 column, the lateral lobes very short and erect or obsolete, the middle lobe short 

 and broad, undulate-crisped, the disk with 2 raised longitudinal lines, the inter- 

 vening space pubescent or glabrous. Column elongated, erect, not at all or 

 scarcely winged. Anther lid-like, incumbent, with a broad flat or convex dorsal 

 appendage, 2-celled. Pollen granular-farinaceous or almost waxy, in 2 deeply 

 2-lobed distinct masses, without any caudicle or gland. — Leafless epiphytes or 

 saprophytes, sometimes climbing to a great extent, the branches flexuose. 

 Flowers in terminal usually pendulous panicles. Bracts at the base of the 

 branches and panicles small or large, but always concave and half-stem-clasping. 



Besides Australia these plants are met with in India, Java, the Indian Archipelago and New 

 Caledonia. 

 Bracts scarcely |'n. long. Labellum pubescent inside between the 



raised lines which end in a transverse callus. Pollen almost waxy . . 1. G. cassythoides. 

 Bracts 1 to 2in. long. Labellum gLibrous between the raised lines which 



converge into one, the lamina on each side marked with diverging 



lines fringed with small linear hairs 2. G. foliata.
