superioribus integerrimis, corymbis multifloris foliosis, involucri foliolis lanceolatis squar- 

 rosis. — Tithonia glutinosa. Collie, MSS. 



Flosculi exteriores radiati, neutri; interiores tubulosi, fertiles. Germen villosum, squamis 2 lanceolatis 

 membranaceis ciliatis coronatum. Eeceptaculum paleaceum, paleis obtusis, apice ad marginem serratis. 



Hab. Valparaiso.— This has considerably the habit of a Grindelia, and Mr. Bridges informs us that it 

 is very abundant on the hills near Valparaiso, growing from four to six feet high. It is called by the natives 

 Maravilla, and a resin which it yields is employed by them for incense in their churches. He has furnished 

 us with fine specimens, both of the plant and its resin.

 19. CENTAUREA. Linn. 

 1. C. chilensis; foliis pinnatifidis, segmentis integerrimis vel pinnatifido-laciniatis acutis 

 glabris, involucro globoso basi subtriphyllo, squamis superioribus apice scariosis pectina- 

 tis. — Bertero in Bullet, des Sc. Nat. 1830. p. 109? (absque descriptione.) 



Hab. Conception. — The marginal florets are neuter, infundibuliform, and radiate; those of the disc her- 

 maphrodite, tubulous, and 5-fid. It undoubtedly belongs to Mr. Don's groupe, Plectocephalus, which we 

 consider a mere section of Centaurea. We have the same plant from Mr. Macrae, gathered on the Cordilleras 

 of Chili, and another variety sent from Valparaiso by Mr. Bridges, having the segments of the leaves always 

 simple and broader, downy on the underside as on the stem : this might be thought a species, but we have 

 an intermediate specimen from Mr. Cruckshanks. 



Ord. XXXV. LOBELIACEvE. Juss. 



1. LOBELIA. Linn. 



1. L. polyphylla ; suffruticosa, caule simplici, foliis oblongo-lanceolatis superioribus 



multo minoribus bracteifbrmibus omnibus confertis argute serratis glaberrimis, floribus 



axillaribus pedicellatis, pedicellis pubescentibus folio brevioribus, calyce hemisphaerico 



pubescente, dentibus subulatis integerrimis, corolla pubescente pedunculum aequante. 



Hab. Valparaiso. — The two lower anthers are bearded at their extremity, the others glabrous. Flowers 

 red. The inflorescence may almost be called a terminal, densely leafy raceme, in which the flower with its 

 pedicel is only the length of the floral leaf. From Mr. Collie's notes we learn that this plant, when cut, yields 

 a milky acrid juice. 



Ord. XXXVI. ERICE^E. Juss. 

 1. ARBUTUS. Tourn. 



1. A.furiens; caule subsimplici pubescente, foliis ovalibus breve petiolatis denticulatis 

 coriaceis margine revolutis supra nitentibus utrinque glandulosis, glandulis pilo terminatis, 

 racemis brevibus axillaribus, rachi pedicellisque pubescentibus squamulosis, calyce glabro, 

 corolla extus glabra intus pilosa. — Qued-qued. Feuill. v. 3. p. 56. t. 43. 



Hab. Conception. — A small low-growing shrub, with few and small leaves at its base, which are almost 

 orbicular. The fruit of this is described by Feuillee as being a reddish-brown berry, which is dangerous 

 when eaten, causing delirium ; whence the Indian name, which signifies madness. 



2. A. punctata ; ramosissima, ramulis pubescentibus, foliis subsessilibus ovato-lanceo-
