N. microcalyx Fisch. & Meyer. Leaves pmnately 3-5-parted or divided, or the 

 upper only 3-cleft ; divisions obovate or cuneate, 2-3-lobed or incised, all approximate 

 commonly the wliole leaf with a triangulate-reniform or cordate general outline ■ appen- 

 dages of the calyx small and inconspicuous, in flower less evident than iu fruit • corolla 

 whitish or bluish, 1 to 2 lines long ; its lobes shorter than the carapanulate tube • the append 

 ages (always?) obsolete: filaments short, inserted rather high on the tube of' the corolla- 

 anthers oval. — Sert. Petrop. I.e.; Gray, Man. 368. N. evanescens, Darby, S Bot N.

 1. c. ; Hook. Comp. Bot. Mag. i. 172. E. ranunculacea, Nutt. 1. c, ex char. —Moist woods' 

 Virginia to Florida, Arkansas, and Texas. Leaves prevailingly and often all but the lowest 

 opposite. Seeds either globular or oval, when young minutely and sparsely pruinose with 

 little papillae, when old with impressed punctures. 



-f— H— Corolla decidedly shorter than the calyx. 



N. breviflora, Gray. A span or more high, at length diffuse : leaves sometimes all 

 alternate, pinnately 3-5-parted ; the divisions approximate, oblong-lanceolate, acute, entire 

 (3 to 9 Imes long): peduncles seldom exceeding the petioles; appendages of the calyx 

 nearly half the length of the proper lobes, both ciliate with long hirsute bristles : corolla 

 whitish or tinged with violet, broadly short-campanulate ; the lobes considerably shorter 

 than the tube; internal appendages cuneate, the broad free summit fimbriate-incised : 

 style minutely 2-cleft at apex : seed solitary, almost filling the cell, globose, nearly smooth 

 and even ; the caruncle evanescent. — Proc. Am. Acad. xl. 315. N. parviflora, Watson, Bot. 

 King, 249, excl. char. — Utah, in Parley's Park, Watson. Literior of Oregon, Tolmie,

 2 Imes in diameter. 



3. ELLlSIA, L, (In honor of John Ellis, an English correspondent of John 



Bartram and of Linnaeus, and who published the first account of Dioncea, &c.) 



North American annuals, with tender herbage, somewhat hirsute ; the once to 

 thrice pinnatifid leaves either all opposite or the upper alternate ; peduncles soli- 

 tary or racemose ; corolla whitish, mostly small in comparison with the at length 

 stellate calyx. 



§ 1. EuELLi'siA, Gray. Ovules in the manner of the tribe all on the inner 

 face of the placentae, a pair to each : seeds globose, uniform, alveolate-reticulated : 

 leaves once pinnately parted. 



B. Nyctelea, L. A span to a foot high, at length very diffuse : leaves on naked or 

 barely margined petioles, the upper mostly alternate ; the divisions 7 to 13, lanceolate, 

 acute, mostly 1-3-toothed or lobed : peduncles solitary in the forks or opposite the leaves, 

 or some of the later ones racemose andsecund: calyx-lobes lanceolate or at length ovate- 

 lanceolate, gradually acuminate, longer than the capsule : corolla cylindraceous-campanu- 

 late, rather shorter than the calyx: seeds very minutely reticulated. — (Moris. Hist. iii.

 ed. 1, &c. — Damp and shady places, New Jersey to Virginia and west to Saskatchewan 

 and Missouri ; flowering through spring and summer. 



B. membranacea, Benth. Weak, a foot or two long, sparsely beset with sliort hirsute 

 or hispid hairs or bristles, otherwise glabrous : leaves mostly opposite, on narrowly winged 

 or margined petioles ; the divisions 3 to 9, linear, obtuse, entire, or sometimes with a lobe : 

 flowers chiefly bractless and becoming racemose on a terminal peduncle; calyx-lobes oblong 

 or at length obovate, very obtuse, rather shorter than the open-campanulate corolla, not 

 exceeding the capsule : seeds rather coarsely reticulated. — Benth. 1. c. 274 ; A. DC. 1. c. ; 

 Gray, Bot. Calif, i. 505. — California, from the Bay of San Francisco to San Diego. Flow- 

 ers very much smaller than in the preceding : corolla 4 lines in diameter, one lobe outside 

 in aestivation. Ovary beset with a few subulate bristles. 



§ 2. EuCRYPTA, Gray, 1. c. Ovules a pair on the back as well as on the face 

 of each placenta ; the seeds of the two dissimilar, oval ; the outer ones (usually
