erect, 7-ribbed. Flower-heads whitish. Flowers dimerous, 

 with 2 sepals, 2 petals, 4 stamens, and 2 stigmas. 



In Bojer, Hort. Maur., p. 361, this species is recorded 

 as native from the neighbourhood of " Grand-Bassin," 

 Mauritius, but it is erroneously named E. qiiinquangidare, L, 



In Baker, Flor. Maur. Seych., p. 390, '' E. quinquangulare, 

 Bojer, non Linn.," and " E. longifolium, Xees, " are erro- 

 neously given as synonyms of " E. rcpens, Lam." Baker's 

 description of E. rejpens. Lam., has been made up partly 

 from this species, but chiefly from E. longifolium^ Xees. 



In Bojer, Hort. Maur., p. 361, E. rcpens is recorded as 

 native in Mauritius, from the same station as E. longi- 

 folium, Nees. E. repens, Lam., was found by me in a 

 forest stream, 1920 feet above sea-level, near the Mare 

 aux Vacoas, Mauritius, on 28th September 1888. Leaves 

 recurved-patent. Scapes 6-13 inches long, erect, marked 

 with 6 longitudinal green lines, alternating with 6 paler 

 green lines. Flower-heads greenish-brown. Flowers • tri- 

 merous, with 3 sepals, 3 petals, 6 stamens in two rows 

 of 3 each, and 3 stigmas. 



With reference to specimens of E. longifolium, Nees, and 

 E. repeals, Lam., forwarded by me to the Eoyal Gardens, 

 Kew, Mr. J. G. Baker wrote, in November 1888, that 

 Bentham pointed out some time ago that these are distinct 

 species, the former having dimerous and the latter trimerous 

 flowers. 



E. longifolium is also a native of Madagascar. 



Naias graminea, Delile. — Pdver, 1100 feet above sea- 

 level, Pliviere de Moka, Mauritius, 23rd October 1888. 

 Also a native of Africa. The genus Naias is new to the 

 flora of Mauritius.

 feet above sea-level, Eiviere de Moka, Mauritius, 6th Decem- 

 ber 1889. A native of Madagascar.

 {fide C. B. Clarke). — Swamp, 1870 feet above sea-level, 

 Curepipe, Mauritius, 15th March 1888.
