Ansellia. 



A. confusa {N. E. Br.). — This differs from A. africana 

 in having the petals scarcely broader than the sepals. Western 

 Tropical Africa. (B. R., 1S46, t. 30, as A. africana; B. M., t. 4965.) 



A. congoensis {Rodigas). — Allied to A. africana^ but freer. 

 It has shorter pseudo-bulbs and smaller flowers, their colour being 

 deep yellow, with purple-brown blotches; lip having whitish side- 

 lobes, veined with purple, and a narrow yellow front lobe. Congo, 

 1S86. {].. ii., p. 64.) 



A. gig-antea {Rclib.fi). — Allied to A. africana, but with smaller 

 hght yellow flowers, transversely barred with brown ; a deep 

 yellow lip, without warts on its middle lobe ; and with more or 

 less crenulate keels. Natal, 1S7S. 



A. humilis (Hort.). — Flowers lemon-yellow, blotched and barred 

 with chocolate: about 2in. in diameter; disposed in large 

 panicles. A compact, free-growing species. Zambesi, 1891. 



A'ar. pallida differs from the type in having the ground-colour 

 of the flowers milk-white. 



A. nilotica (N. E. Br.). — This has pseudo-bulbs about 2ft. 

 long, and large flowers of a deep yellow colour, with large 

 blotches of dark brown. It is the finest of all known Ansellias. 

 Upper Nile Regions. Syn. A. africana nilotica. 



APPENDICULA. 



About a score of species of stove, epiphytal Orchids, 

 belonging to the tribe ]'aHdciU, are found in the genus 

 Appeudicula [Bluinc). All ha\-e tufted leaf-stems. They 

 are nati\-es of tropical Asia, Australia, and Polynesia. 

 The name is from Appendix, and is in allusion to the 

 appendage at the base of the lip. Flowers usually minute ; 

 sepals connivent, the lateral ones connate at the base, 

 and adnate to the produced foot of the column, forming 

 a mentum ; petals variable ; lip erect, inverted on the foot 

 of the column, or with its sides adnate thereto ; column 

 very short, the rostellum erect, bifid. About four species 

 {A. bifaria, A. callosa, A. moiioccras, and A. Pcyeriaiia) are 

 ultivation, but the\' are only of botanical interest.
