foliata, floribus fasciculatls. Gaud iu Freyc. Voy. p. 469. t. 84. — It must be observed, however, that his speci- 
mens seem to have been even less advanced than ours, and this circumstance may also account for the slight 
difference in the generic character, which we shall now give as more suited to the specimen before us : — 
Dubautia. Gaud.; luvolucrum campauulatum suboctophyllum, foliolis liberis margine sibi mutuo incum- 
bentibus. Flores 8-10, tubulosi, hennaphroditi. Filamenta linearia, apice vix incrassata. Stigmata dila- 
tatii acuta ciliata. Achenium oblongum. Pappus paleaceus dorso et margine setis patentibus rigidis plum- 
osus. — Suffrutices, ramis apice foliosis, inferne nudis, cicatriso-annulatis. Folia opposita, sessilia, basi sub- 
connata, rigida, parallele venosa. PaniculcB terminales ; ramis hispide setosis. — This genus is most allied to 
Tridax and Craspedia. It has also some affinity to the new genus Failliarda^ of which we possess three 
new species from Mr. Menzies and Mr. Macrae, aU from the Sandwich Islands. 
Ord. XXIV. LOBELIACE^. Juss. 
1. Lobelia (Delissea) acuminata; ramosa, foliis oblongis duplicato-denticulatis utrinque 
hirtellis, calycibus 5-dentatis. Gaud, in Freyc. Voy. p. 457. t. 76. 
As the characters of Delissea and the two following genera, whether they be viewed as distinct genera, 
or only as sections of Lobelia^ are only to be found in the above-cpioted work, we shall transcribe them here. — 
Delissea. Gaud.; Calyx ovario arete adnatus, hmbus liber 5-dentatus persistens. Corolla tubulosa, 
arcuata, decidua, tubo cylindraceo indiviso, hmbo 5-partito subbilabiato. Stamina 5 ; filamenta in tubiun 
liberum conuata; antherse coluereutes, 2 inferiores barbatse. Stigma bilobum, pilis cinctum. Capsula 
baccata, calyce persistente coronata, bilocularis non dehiscens. Semina creberrima. 
2. Lobelia (Cyanea) Grimeseiana. — Gaud, in Freyc. Voy. p. 458. t. 75. 
The character of this sub-genus is: — Cyanea. Gaud.; Calyx ovario adnatus 10-sulcatus; limbus foliaceus 
longior 5-partitus, laciniis oblongis margine reflexis et undulato-crispis. Corolla tubuloso-cylindracea, arcu- 
ata, limbo 5-partito subbilabiato. Stamina 5 : tubus stamineus liber. Antherie connatae, barbatse. Capsula 
baccata, sulcato-decagoua, iudehiscens, bilocularis, calyce persistente coronata. Semina crebemma. 
3. Lobelia ( Rollandia) lanceolata ; ramosa, foliis magnis oblongo-lanceolatis duplicato- 
dentatis siibtus hirtellis, calycibus 5-partitis glabris, laciniis ovatis obtusis, racemis depauper- 
atis, staminibiis epipetalis. Gaud, in Freyc. Voy. p. 458. t. 74. (R. montana.) 
The specimen in the Collection has much larger leaves than that figured by Gaudichaud, to which another 
in our herbarium, from Mr. Macrae, exactly corresponds; but to the latter the term folia magna can 
scarcely be applied, while those before us well deserve the name, being from a foot to a foot and a half long. 
Gaudichaud thus characterises Rollandia : — Calyx ovario arete adnatus ; limbus liberus 5-partitus, laciniis 
abbreviatis obtusis. Corolla tubulosa, lateribus compressa arcuata, tubo indiviso, limbo 5-pai'tito subbilabiato. 
Stamina 5 ; tubus stamineus inferne parti superiori corollie adnatus. Anther® coluerentes bai’batee. Stigma 
bilobum pilis cinctiun. Capsula baccata, indehiscens, bilocularis, calyce persistente coronata. Semina creber- 
i-ima.— The genus Clermontia, Gaud., was not observed during the expedition under Capt. Beechey : we, how- 
ever, possess C. oblongifolia and grandifiora. Gaud., from Mr. Macrae. This differs from the former genera 
by the calyx being coloured, tubular, curved, and as long as the tube of the corolla. 
4. Lobelia macrostachys ; glaberrima, caule elato stricto, foliis lineai’i-lanceolatis utrinque 
attenuatis suberenatis, racemo simplici terminali longissimo, pedicellis simplicibus secundis 
horizontalibus apice sursum vergentibus, bractea lineari pedicello breviore, calycis tubo 
hemisphserico, limbi laciniis obtusis, corolla pedicello duplo longiore. 
Calyx ovario arete adnatus ; limbus liber, 5-partitus ; laciniis oblongis, obtusis, tubum mquantibus. 
Coro//a tubulosa, duas ad tres uncias loiiga, arcuata ; tubus cylindraceus 5-lidus, hinc fissus. Stamina b;
