 oblong or lanceolate, acutish, nearly entire (inch or two long), tapering at base into a short 

 margined petiole : flowers in globular and sessile interruptedly spicate glomerules, the upper 

 naked and approximate, the lower remoter in the axils, some short-peduncled : corolla

— 1. VOYRIA. Corolla salverform, bearing the stamens below the throat. Anthers short. 

 Stigma undivided. Seeds very numerous, tailed at both ends. 



— 1. VOYRIA, Aublet. (Unexplained name.) — Leafless and colorless 

 (white) little herbs, of Tropical America, parasitic on decaying trunks, &c, 

 bearing small subulate scales for leaves, in the manner of Bartonia. 



V. Mexicana, Griseb. Stems a span to a foot high, slender, bearing a cyme of several 

 flowers : corolla white or flesh- color, a quarter of an inch long. — Gent. 208, Prodr. ix. 84, &

E. nudicaulis, Exgelm. A span or two high, cymosely branched from the conspicuous 

 tuft of rather large roundish radical leaves : cauline leaves few, linear : flowers long- 

 peduncled : tube of corolla not surpassing the calyx ; lobes a little shorter, oblong, obtuse :

 Proc. Am. Acad. xvii. 222. — Along streams in Santa Catalina Mountains, S. Arizona, 

 Pringle. 



E. ventista, Gray. Add : Bot. Mag. t. 6396. — This and all the larger-flowered American 

 species are dichogamous in the manner of Sabbatia, the style in the earlier anthesis declined

4. EtTSTOMA, Salisb. 



E. silenifolium, Salisb. (Parad. Lond. t. 34), is the name which should have been retained 

 for E. exaltatum, Griseb. In S. California this certainly becomes perennial, according to

G. gracillima, Bertol. Misc. Bot. xiv. 19, t. 3, is Apteria setar.ea,TSutt. — Add on p. 119 : —

 thinner-leaved, and wholly destitute of crown to the corolla, in this and the habit approach-
