Hartwegia (Theodor Hartweg collected in Mex. for the Horticultural Society of London, and found these plants near Vera Cruz). Orchidaceae. Tender epiphytic orchids from Trop. Amer., growing about a foot nigh and bearing purple fls. The genus has the habit of Epidendrum, section Amphiglottis, but differs in having the labellum saccate at the base, in which respect the genus approaches Ponera; however, Ponera has a very different habit.—Two species. Rest them in a coolhouse Oct. to March. Growing temperature should be 65-90°.

H. gtomma, Reichb. f. "This is a most lovely Rem," wrote Reichenbach, and "much better than its predecessor." Gemma, therefore, probably does not mean "twin," in this case. Lvs. solitary, semi-terete, thick, acute, channelled, blotched with blackish violet: fls. amethyst-purple, in a small, 1-branched panicle; odd sepal acute, obtusely strap-shaped, equal sepals oblong-acute. Cent. Amer. L.H.B.
