dimorphism, which is obvious in the Batscliia section (altliough not 

 demonstrated in all of the species), may pervade the genus.*

 make a few corrections to my paper on the American species, pub-

 ized thus. 



1. Corolla ut videtur pallide flava : folia floralia minora, calyces fructifei'os 

 haud superantia. 



L. MULTiFLORUM Toff. ill herb.; S. Wats. Bot. King (adnot), p. 238. L. 

 pilosam Gray in Sill. Jour. 34, p. 2.56, & in Proc. Acad. Philad. 1863, non Nutt. 

 — Colorado in the lower mountains toNaw Mexico and Te.xas. The throat of 

 the corolla is nearly naked. Nuttall's L. pilosum is the same as L. riiderale 

 Dougl. & Hooker. I was misled into taking this species for it through Nuttall's 

 reference of his to Batschia, and his idea that the corolla was yellow, whereas in 

 that species it is only yellowish in the manner of L. officinale. 



2. Corolla aurea Yel aurantiaca : folia floraUa pleraque conf ormia, calyces 

 superantia, 



•»- Oblonga vel ovata : corolla nee tubo prselongo, nee plicis faucialibus fornicato- 

 inflexis. 



L. Califorxicdm. Ptibe molli hirsutum; foliis lanceolatis ; corolla flava, 

 tubo calyce sesquilongiore, fauce ampliata 5-loba, lobis brevibus, plicis fauciali- 

 bus obsoletis, annulo ad basira tubi nudo. — L. canescens var. Torr. Bot. Whipp. 

 p. (68) 124. — Grass Valley, California, Dr. Bigelow. The anthers are high and 

 the style short ; but this is probably only one form. 



L. CANESCENS Lchm. Pube molli primum canescens : corolla laete aurea, 

 plicis faucialibus pubescentibus prominulis, annulo basilari nudo. — L. sericeum 

 Lehm. nuist belong to this, but the synonym Anchusa Virginica Linn, is to be 

 excluded. I do not know what the glabrous plant in the Linnaean herbarium is ; 

 but the Gronovian plant is an Onosmodium, Morison's is probably Litltospermum 

 hirtiun, which is the Puccoon of the Southern States, and Plukenet's may be 

 either species. 



L. HiRTUM Lehm. Pube hispida demum asperum; floribus majoribus ; 

 corolla Isete aurantiaca, plicis faucialibus prominulis, annulo basilari dentibus 

 10 hirsutissimis instructo. — L. Bejariejise DC. is of this species. 



t- 1- Folia omnia linearia angusta : corollae bene evolutae tubo praelongo, plicis 

 faucialibus fere fornicatis, lobis inciso- vel undulato-crenulatis. 



L. ANGUSTiFOLiUM Michx. L. linearifolium Goldie? Pentalophus loncjiJlorKS 

 & P. Mandanensis A. DC, cum syn. cit. etc. L. hrevijlorum Engelm. & Gray, 

 PI. Lindh. 1, p. 44. — It is to Mr. Bebb (see Amer. Naturalist, 7, p. 691) that we 

 owe the demonstration that the long-flowered species (L. incisum Lehm. &c.) is 

 the perfect form, as we may say, which, later in the season and especially upon 

 lateral shoots, goes on to produce depauperate flowers, with corolla and style 

 hardly equalling the calyx, and without doubt of cleistogenous fertilization. In 

 this state it is L. anrjustifolium Michx. — the earliest and an appropriate name.
