Nearly allied to Baccharis mucronata of this work, (p. 30,) which, from an examination of better 
materials, we have now ascertained to belong' to the present genus, along with many other Chilian supposed 
species of Baccharis. 
1. Diplopappus villosus; subdecumbens, hirsute villosus, caule ramoso, ramis subcorym- 
bosis, foliis sessilibus integerrimis lineari-oblongis subspathulatis acutis margine scabris 
inferne ciliatis, floribus fastigiatis. Nutt. — Chrysopsis villosa. Nutt. Gen. v. 2. p. 151. — 
Amelins villosa. Pursh. 
The only specimen in the Collection agrees with Nuttall’s specific character. Diplostephium of Kunth, 
and Chrysopsis of Nuttall, are synonymous with Diplopappus of Cassini. 
1. Grindelia squarrosa; glaberrima, caule berbaceo, ramis breviusculis corymbosis, foliis 
anguste oblongis amplexicaulibus serratis, involucri glabri squamis apice angustis squarrosis. 
— Dun. — Donia squarrosa. Pursh, FI. Bor. Am. v. 2. p. 559. Bot. Mag. t. 1706. 
a. Folia punctis glutinosis micantibus conspersa. 
jS. Folia subintegerrima carnosula opaca. 
Although we do not consider these two varieties as distinct species, yet it must be confessed their 
aspect is very different. Our second variety has quite that peculiar appearance which many plants assume 
which grow on the sea-shore ; but we are ignorant if this be its true locality. Most authors unite this 
species with G. inuloides, Willd.; and if they be correct, then the following species stands in a similar 
situation, for it is in many points intermediate between the two others. 
2. Grindelia hirsutula; pilis albidis birsutula, caule coespitoso berbaceo parce ramoso, 
ramis elongatis unifloris, foliis angusto-oblongis subamplexicaulibus serratis, involucri 
pubescentis squamis lineari-lanceolatis basi appressis apice subsquarrosis. 
Very closely allied to G. angustifolia, Kunth, (not Dunal,) but that species appears to have always a 
simple stem. This differs from the preceding, by the hairs that are found on its stem, leaves, and involucre, 
and by the long one-flowered branches. 
3. Grindelia humilis; glabra, caule berbaceo simplici unifloro, foliis radicalibus linearibus 
obtusis basi attenuatis caulinis sessilibus inferioribus angustissime linearibus superioribus 
subulatis bracteiformibus, involucri foliolis lineari-lanceolatis apice squarrosis. 
The only specimen in the Collection is about eight inches high, and is very unlike any of the other species. 
The cauline leaves decrease gradually upwards, resembling subulate bracteae. On this plant Messrs. Lay 
and Collie remark: — “ folia recentia lineari-spathulata, antiquiora objonga basi dilatata spinuloso-dentata;” 
the latter kind of leaves we have not seen. 
1. Baccharis glutinosa; fruticosa, foliis anguste lanceolatis basi in petiolum attenuatis 
argute remote serratis 3-plinerviis subtus excavato-punctatis, corymbis terminalibus, involu- 
cri foliolis margine laceris, aclienio scabro. — Pers. — Molina salicifolia. Ruiz et Pav. 
Syst. p. 210 ? 
Perhaps B. salicifolia, Pers., is not distinct, but then Sprengel unites to it B. gnidiifolia, Kunth, of which 
plant the leaves are described as sessile, and not attenuated into a kind of petiole at their base, as in ours. 
Chamisso does not appear to have met with this species ; but Lessing (Linnsea, v. 6. p. 505,) mentions 
having found B. linearis, which is surely distinct, otherwise we might have supposed that Lessing and we 
had the same plant in view. We can perceive only one series of hairs of the pappus. 
2. Baccharis glomeruliflora ; fruticosa, foliis approximatis obsolete trinervibus obovatis
