Hab. Galapagos, Douglas. No doubt James Island; the only one I believe upon which 
Mr. Douglas landed. 
There is no specimen of this plant in the Hookerian Herbarium.

Hab. James Island, Charles Darwin, Esq. 
These specimens do not differ from others of North Africa, which are not 
hairy at the lower base of the panicles. Except with very slight variations in 
the size and acuteness of the florets, the same plant is found in Peru, the East ` 
Indies (sub nom. P. punctata, Roxb., paleze sometimes scariose), North Ame- 
rica (P. tenuis, Ell. ò. capillaris), Buenos Ayres, Brazil (P. polytricha, Nees), 
and Mexico and Brazil (P. Mexicana, Link), specimens of which last, in the 
Hookerian Herbarium, from Hort. Reg. Berol, entirely coincide with the 
Galapagos Island plant.

Hab. Var. paniculá elongata, vaginis hirsutis, culmis erectis.—Albemarle Island, Mr. Macrae. 
Var. panicula coarctatá, vaginis pilosis, culmis suberectis.—Chatham Island, Charles 
Darwin, Esq. : 
Var. panicula ellipticá vel elongato-ovatá, vaginis glabriusculis, culmis tenuibus pro- 
cumbentibus.—Charles Island, Charles Darwin, Esg.

Heterostegon curtipendulus et Eutriana curtipendula, Schweinitz in Herb. Hook. 
Hab. North America, Schweinitz. St. Louis Missouri, and Texas, Drummond. 
Very nearly allied to E. curtipendula, but differs in the much smaller orien which bear more 
numerous (generally 6) flowers. The upper flower too has almost invariably 2 palez, and is more 
perfect than in that species. 
3. E. gracilis, Hook. fil.; glaberrima, panicula stricta erecta spiculis secundis sessilibus trifloris, glumis 
inzqualibus superiore flosculum solitarium equante subacutà integra, paleis subsequilongis infe- 
riore apice breviter bicuspidatà; superiore latiusculà convolutà spite bifida dorso basi setulâ sub-

acumen elongatum gradatim productis. 
Hab. Tucuman, Tweedie. 
A most distinct species, 
leaves and slender habit.
