120 PHANEROGAMIA. 



Both the ordinary form of the species, and some very dwarf ones 

 occur in the collection. The latter are only one or two inches high, 

 with crowded or even imbricated leaves, and solitary, short-ped uncled 

 flowers : they accord with those referred to this species by Dr. Hooker, 

 as his variety Fuegianum. 



2. Cerastium vulgatum, Linn, {ex Fries). 



Var. Peruvianum : caulibus superne pedicellisque glanduloso-pubes- 

 centibus; foliis plerumque linearibus ; petcdis nunc calyce glanduloso 

 paidlo longioribus nunc plane nullis ! 



Var. Andinum : nanum, condensatum, vix glandidosum ; foliis oblongo- 

 linearibus ; petalis calyce paullo brevioribus. 



Hab. Banos, Andes of Peru (var. Perumanum) : also gathered near 

 Quito by Prof. Jameson. Above Obrajillo and Alpamarca, on the high 

 Andes of Peru (var. Andinum) . 



The first variety well accords with my specimens of Cerastium 

 Beeringiamim, Cham. & Schlecht. (which Fenzl., in Ledebour's Flora 

 Bossica, reduces to a form of G. vidgatum) ; except that the flowers 

 are rather more glomerate, and most of the later ones are wholly 

 apetalous, as in a corresponding variety of G. viscosum. The upper 

 part of the slender stem and the pedicels are strongly pubescent 

 with spreading glandular hairs, while the calyx is beset with sessile 

 glands. The cauline leaves are all linear, from 6 to 10 lines long, and 

 only a line wide. The capsule, seeds, &c, are just as in 0. vulgatum. 

 — The var. Andinum is, I suppose, a more dwarf and condensed form 

 of the same species, growing at a greater elevation. It is smaller in 

 all its parts and less glandular; the leaves oblong-linear. I think that 

 both belong to the same species, and that they cannot be satisfactorily 

 distinguished from C. vulgatum, as that species is now received by 

 Prof. Fenzl.
