it must be placed in sect. I,, with bellshaped perianth and iipper parts of filanients 

 free; Nuno is characterised by filaments free almost to their base. 



Few Falkland plants have more conspicuoiis flowers. The white, lilac-striped 

 perianth is 15 mm across the mouth, and very fragrant with a scent of clover. The 

 pedulous flower is distinctly proterandrous; the pollengrains are easily shaken out by 

 the wind, the anthers are versatile. The stamens become slightly bent oiitwards, 

 the style is stretched and its branches separate. I found an abundance of germinat- 

 ing pollen-grains on the papillse; as there is still pollen left, when the stigmae are 

 ripe, selfpollination is easily effected on account of the position of the flower. In 

 spite of having observed the plant dnring its entire season, I could iiever discover a 

 visitor. It flowers in the spring when insects are scarce. Nevertheless it bears 

 plenty of fruit.

777. A. macroptera Kränzl. (A, odoratissima Poepp. et Endl. in Fl. ant. etc, 

 A. acutiflora Poepp. et Endl. sec Kränzlin in herb. meo.) — Pl. I, Fig. 5. 



I have never seen any fully developed, living specimens, for I had to leave 

 the West Falklands too early. However, Mr. Felton had thegreat kindness to 

 send me a good material of an Äsarca, which was determined by Professor Kränzlin 

 as A. acutiflora. It does not agree with the original plants of Poeppig nor with 

 his description or figure of this species (Nov. gen, et spec. plant. 11. p. 13, t. 118). 

 I have seen the Falkland material in Kew of A. odoratissima and it belongs to liere. 

 A comparison with the type of Poepptg's odoratissima shows that it is not identical 

 with that species. 



I cannot be quite sure of my determination; the plant agrees very well with 

 Kränzlin's description and figure of the labellum (Orchid. gen. et spec. p. 38, tab. 

 III B), only dif tering in the presence of incrassate nervs on the petals, but I have 

 not seen any authentic material. A. macroptera differs from all other species except 

 A. litoralis Reiche in the non-incrassate points of the lateral sepals. Reiche (Orchid. 

 Chilenses. An. Mus. Nac. Santiago Secc. II: 18, 1910) identifies A. macroptera with 

 Chlorcea litoralis Phil. = A. litoralis Reiche; Kränzlin 1. c. has C. litoralis = C. 

 Fonckii Phil. The plant in Berlin, labelled C. litoralis by Philippi, is undoubtedly 

 a Chlorcea and not at all the same as the plant described by Reiche 1. c. It is 

 possible that his A. litoralis and Kränzltn's macroptera are the same species, but 

 this has to be proved.
