NEW AND LITTLE-KNOWN MADAGASCAR PLANTS. 59 



Allied to the preceding, but with broader segments, more 

 obtuse lobes to the lip, and other characters. The radical leaves 

 appear to be wanting, but the cauliae ones (two oa one specimen, 

 and one on each of the two others) vary from \ to 1$ inches long 

 and from 2 to 6 lines wide. 



Satyrium rostratum, Lindl. 



Hillsides and wet places near Ankaratra Mountains, Interior, 

 1955 ! 



S. giganteum, RidL (Journ. Linn. Soc, Bot. xxii. p. 126), seems 

 quite identical with Lindley's plant, which may have been over- 

 looked when the former was described. I have carefully dis- 

 sected a flower from each of the type specimens, side by side, 

 and cannot detect any difference between them, while in stature 

 and general appearance they are also indistinguishable. 



Satyrium trinerte, Lindl. 



Near pools of water (alluvial), Moromonga plain, Tamatave to 

 Capital, 1757 ! Near water, Arivonimamo, 1929 ! 



Satyrium: am(exum, A. Rich. 



On tops of Ankaratra Mountains, Interior, 1981 ! 



DlSA INCARNATA, Lindl. 



Near streams, Arivonimamo, Lake Itasy, 1940 ! 



Disa Buchenaviaxa, Eranzlin. 



"Wet places in rank grass at 4500-5000 feet on the Andringitra

Mountains, Interior, 1832 ! u Flowers bluish purple. 



Disperis tripetaloidea, Lindl. 



On humus in woods near Fort Dauphin, 2305 !, 2731 ! 



IRIDE.E. 



Geissorhtza Bojeri, Baker. 



Capsule obovate-oblong, 1-3 cm. long and Gmm, broad. (The 

 narrow cylindrical form of the capsules in Parker's specimen 

 (Herb. Kew) is therefore probably abnormal : cf. Benth. & 

 Hook. f. Gen. Plant, vol. iii. p. 703.) 



Ankaratra Mountains, 2092 ! 



AMAETLLIDE^E. 



Hypoxis angustifolia, Lam. 



Several localities, 2517 ! 2195 ! 2417 ! 1818 ! The last number 

 contains specimens only about 3 inches high, while some of the 

 others reach 18 inches.
