of the southern branches of the Columbia. Eschscholtz describes the stem as biennial, and suffruticose ; but 

 the latter term is probably only applied to mark the rigidity of that part; in our gardens it appears to be 

 annual. 



Okd. XXIX. BORAGINE^. Juss. 



1. Myosotis Chorisiana; biennis, subcaespitosa, caulibus adscendentibus subsimplicibus, 

 foliis linearibus, racemis inferne foliosis, pedunculis folio plus dimidio brevioribus, calyce 

 5-partito laciniis lanceolatis acutis sub fructificatione patulis, tubo adpresse strigoso-piloso, 

 nucibus rugosis. — Chamisso in Linncea, v. 4. p. 444. 



This species approaches in some points to M. nana, Vill., M. clavata, Ledeb., and M. humilis, Ruiz and 

 Pavon ; but it differs from them all.

1. Nemophila Menziesii; foliis omnibus pinnatifidis scabris segmentis approximatis 

 ovatis obtusis ciliatis subtridentato-lobatis, pedunculis oppositifoliis folio duplo longioribus, 

 segmentis calycinis lanceolatis accessoriis minutis. 



Allied to N.phaceloides of Barton ; but a much smaller plant in every respect; and the peduncle is also con- 

 siderably longer in proportion. The leaves are precisely those of N. parviflora, a species found by Dr. Scouler 

 and Mr. Douglas on the Columbia River; but in that individual the flowers are very small, and the peduncles 

 scarcely so long as the leaf. The species has long existed in Mr. Menzies's Herbarium, and in those of 

 his friends, to whom he liberally communicated specimens. Mr. Collie remarks that the capsule is poly- 

 spermous. 



1. Phacelia circinnata. Jacq. — P. Californica. Cham, in Linnaa, v. 4. p. 494. — P. Peru- 

 viana. Cham. I. c. 



We cannot agree with Chamisso that there are sufficient characters to separate the above synonyms, 

 indeed from Chili we have received intermediate states. Pursh's character of his P. heterophylla applies 

 equally to our plant. 



Ord. XXXI. SOLANE^. Juss. 



1. Solanum nigrum, var. Virginicum. Linn. — S. pterocaule. Dun. Sol. v. I. p. 153. 



Of this there are two states in the Collection; one with the leaves glabrous, the other with them more or 

 less puberulous beneath. In both, the angles of the stem are rough, or almost prickly. 



2. Solanum umbelliferum ; incano-puberulum, caule suffruticoso, foliis petiolatis ovatis 

 subacutis integerrimis, racemo umbellato terminali paucifloro, calyce urceolato quinquefido 

 laciniis acutis, corolla calyce triplo longiore quinquefida. — Eschscholtz, in Mem. Acad. Imp. 

 St. Peter sb. v. 10. p. 286. et in Linncea, v. 4. Litter, p. 148. 



In addition to the character given by Eschscholtz, we may remark that the stamens are distinct, the 

 filaments very short, and broadest at the base. Style straight. Stigma slightly capitate. Before the corolla 

 is fully expanded, it appears campanulate, as in Atropa, with which genus the present individual has con- 

 siderable affinity. The anthers are, however, furnished with two pores, or rather clefts, at their apex • but 

 in some flowers, these pores showed a tendency to split downwards to the base of the anther.
