generally very loose, ovate, not turbinate. Flowers generally 

 incomplete ; calyx 4-cleft, rarely 5-cleft. Stamens one or two. 



4. Chenopodiiim acutifolium. — Near Bangor, August 26, 

 1828. — Edge of the seed horizontal; pellicle or capsule tur- 

 binate, tightly enclosing the seed ; at the base of the pellicle 

 is fastened the umbilical cord, which lies in a groove on the 

 edge of the seed, to which it is attached at the notch ; in this 

 instance lateral (not lowest.) Seed not distinctly dotted. 

 Calyx generally 5-cleft, one or two of the stamens often 

 wanting. Stem irregularly 4-sided. 



5. Beta wanWma. — Anglesea, July 24, 1826. — Styles sl-ways 

 three : germen 3-sided ; when the seed is nearly ripe, the 

 germen becomes purple and granulated. Flowers often three 

 together. 



6. Salsola Kali. — Anglesea, August 8, 1826. 



Gen. Char. Calyx (I believe) 5-leaved; leaves ovato-lanceo- 

 late, acute, keeled, the base of each overlaying the other. 

 Capsule not imbedded, but surrounded by the calyx. — Spec. 

 Char. Bracteas fringed with spinulae. Calyx not dilated 

 until after the impregnation, and without any appendage 

 at first ; although, at an early stage, the place where it 

 originates is visible as a transverse green line, a little 

 below the middle of each leaf of the calyx. This soon 

 expands into a membranous, shining, unequally lobed 

 or wavy appendage : the calyx-leaves remain erect, as at 

 first, and not otherwise altered than in being a little 

 dilated and more fleshy and concave within. 



7. Ulmus montana. — May, 1827. — The seed of U. montana 

 is without albumen. Cotyledons ovate. 



8. Cuscuta Epithymum. — Near Holyhead, July 17, 1828. 

 Gen. Char. Embryo not horizontal, I believe, in this 



species, but vertically convolute, not spiral, surrounded 

 by albumen, which also passes through the curve of 

 the embryo. Both the skins of the seed are thick, 

 the outer granulated or papillose. — Spec. Char. Fila- 

 ments inserted at the top of the throat, the scales of the 

 corolla placed below them, near the base of tlie throat,
