Hills, Tennessee, April-May, Dr. Cnrrey ! — Flowers apparently wMte, 

 or pale rose-color. The transverse process in the fruit is like that of Modiola, 

 except that it is situated near the summit of the cell.

 Nuttallia malvasflora, Fisch.. t^ Trautv. inch sem. St. Petersb. 1838. — 

 Our specimen from Mr. Douglas's Californian collection is probably the 

 species referred to in the work cited above ; but the flowers are more than 

 twice as large as even in our cultivated specimens of S. malvreflora received 

 from Sir Wm. Hooker. We strongly suspect that S. Oregana, Nutt. and 

 even S. delphinifolia, Nutt. are only varieties of this species.

16 («). S. grossulariafolia (Hook. & Am.) : hoary with a stellate pubes- 

 cence ; leaves cordate, 3-5-parted ; the segments cuneiform, 2— 3-cIeft ; pe- 

 duncles axillary, 3-5-flowered ; calyx 5-cleft, with 2-3 subulate deciduous 

 leaflets at the base. Hook. S^' Arn. ! I. c. 



Bamcock River, (Snake Country), Oregon, Mr. Tolmie ! — Flowers large, 

 red, resembling those of S. coccinea and S. dissecta, but quite different in the 

 foliage. Hook. Sf Am.

11. PAVONIA. Cavan. diss. 3. p. 132 : Lam. ill. t. 585. 



Calyx 5-cleft, surrounded by a few- or many-leaved involucel. Ovary 5- 

 (rarely 4-) celled ; with a single ovule in each cell : style 8-10-cleft at the 

 summit. Carpels united into a 5-lobed 5-celled capsule; each 2-valved, one- 

 seeded. Radicle inferior. Frutescent, or rarely herbaceous plants. 



1. P. Drummondii : leaves roundish-cordate, somewhat 3-lobed, rather 

 obtuse, crenately toothed, pubescent above, velvety-tomentose beneath ; 

 flowers 4-6 together, clustered at the summit of elongald axillary peduncles 

 and flowering branches ; leaflets of the involucel 8-10, linear-spatulate, 

 rather shorter than the calyx ; carpels glabrous. 



Texas, Drumjnond I — Stem shrubby and apparently tall, softly pubescent. 

 Leaves 2-3 inches in diameter, with 3 short lobes. Flowers scarlet, about 

 an inch long. Stamineal column at length much exserted. Capsule red, 

 formed of 5 ovate very obtuse carpels, which finally separate and split into 2 

 valves. Seeds glabrous. — Allied apparently to P. paniculata of Cavanilles. 



Order XXXVIII (a). BYTTNERIACEtE. R.Br. 



Sepals 5, more or less united at the base, naked or involucellate : 

 aestivation valvate. Petals hypogynous, equal in number with the 

 sepals, often saccate at the base and variously lengthened at the 

 apex, with a twisted or convolute aestivation, sometimes M'anting. 

 Stamens hypogynous, as many as the petals or more numerous, more 

 or less monadelphous ; some of them often sterile : anthers 2-celled, 

 extrorse. Ovary of 5 or rarely fewer carpels, which are more or less
