Chilense to G. Piravira, Mol=, which is the same as our G. citrimm, a name that of course must yield to 
that of Molina’s, although we are yet ignorant where it is published. When Lessing referred hither the G. 
Chilense, he must have trusted a little to Sprengel’s character, as we did, for no other' plant of Chamisso, 
from whom Sprengel had it, approached more closely. At p. 260, Lessing informs us that he had overlooked 
a packet, the description of which would form a supplement. Among these he adopts the G, Chilense, Spr., 
from California, and although, perhaps inadvertently, he refers to the former part, where he united it to G. 
Piravira, yet he now adopts the name from Sprengel j contrasting which with the character given by that 
author, w^e have now no doubt of the present being what he intended ; and as it is not a Chilian, but a 
Californian plant, we have considered it necessary to change the specific name. To G. lanuginosum, Kunth, 
it is very closely allied | but although Sprengel unites them, we consider the leaflets of the involucre “ argute 
acuta fuscescenti-virescentia” of the latter, may keep it distinct. Sprengel places this plant erroneously 
among the “ Filagines,” but it is much more nearly allied to G. polycephalum, and particularly to G. 
decurrens. We may here remark, in addition to the two Chilian species already noticed, and described at p. 31 , 
that our G, utophyllum coincides with Lessing’s G. Indicum, and G. coarctatum with his G, stachy difolium.

decurrentibus supra scabriusculo-puberulis subtus albo-lanatis, corymbis paniculatis glomer-

In the specimens before us, the leaves are narrower than in those we possess from the United States, 
and the panicle more destitute of foliage, but we can see scarcely any other difference. The Avoolly coat on 
the underside of the leaves is subject to be rubbed off. The Californian state approaches very nearly to G. 
Sprengelii, above described, from which it principally differs by the leaves not being cottony on both sides.

This was also found at California by Mi% Meuzies, and it extends as far north as Nootka Sound.

auriculis acutis, pedunculis sub flore incrassatis supra medium bracteolas duas lineares ger-

The style is bifidj stigmas two, globose and w'hite; so that this is not a Convolvulus, as defined by Brown, 
but an Ipomaa.

At the time Dr. Hooker published this species in the Botanical Magazine, he was not aware of a specific 
name being already given to it by Eschcholtz, which, however, has the claim of priority. Messrs. Lay and 
Collie appear to have found it about Monterey, Blr. Douglas near the source of the Multnomack River, one
