1. Malva rotundifolia. Linn. — De Cand. Prodr. v. l.p. 432. 
1. Hibiscus Youngianus ; caule fi-uticoso velutino aculeato setifei’o, foliis corclatis subtri- 
lobis dentato-serratis, involucelli foliolis 10 teretibus apice divaricato-bifidis. — Gaud, in 
Freyc. Voy.p. 91 ? (absque descriptione.) 
Caulis fruticosus, dense velutinns, setis conspersus, aculeatus (secundum Collie, at aculei a nobis non visi.) 
Ramuli velutini setiferi. Petioli relutini duas poUices longi. Folia cordata, 3-5-lobata, angulis obtusis, lobo 
medio productiore, irreg-ulariter dentato-serrata, petioliun long-itudine aequantia, subtus velutina, supra scabra. 
Pedunculi solitarii, axillares, velutini, setiferi, petiolum vix superantes. Involucelli foliola 10 teretia bispido- 
setosa apice biloba, lobis parvis patentibus. Sepala 5 ad medium coalita, dense setifera, dorso margineque 
nervosa, reticulatim venosa. Petala “ rosea” ( Collie.) Carpella polysperma, truncata, dorso pilis albidis 
rigidis appressis dense tecta. Semina subreniformia, gi-isea, glabemma. 
We have no authority for supposing this to he the H. Youngianus of Gaudichaud, farther than that he 
states it to be a new species of the section Furcaria of De CandoUe, to which ours certainly belongs, and is 
a species closely allied to H. bifureatus, Cav. It was found in Oahu. 
2. H. Boryanusf De Cand. Prodr. v. l.p. 446. 
From the imperfect state of the specimen before us, we cannot affirm it positively to be the plant of De 
Candolle. The leaves are ovate, slightly coriaceous, 3-nerved, perfectly smooth, and quite entire. The pe- 
duncles are short, scarcely an inch long, and very stout. The calyx 5-toothed, and split up on one side by 
the swelling of the fruit, as in De Candolle’s section Manihot. The carpels are polyspermous, and the seeds 
covered with fulvous hairs. Perhaps, then, this is a new species, and more closely allied to H. rhombifolius, 
Cav. ; but we possess a plant in flower from Owhyhee, collected by Mr. Macrae in Byron’s Bay, wbich seems 
to be the same as ours : this certainly belongs to the section Cremontia by the nature of its corolla, and 
has toothed leaves, as in H. Boryanus: the flowers are, however, red, not white, and the leaves are 
3-nerved, as in the specimen from Oahu.

Found in Oahu, where it was also met with by Nr. Macrae. It dififers principally from S. ulmifolia of 
CavaniUes, by the leaves being not acuminated and scarcely at all pubescent ; but we do not consider it a 
distinct species.

There are three states of this species in the Collection j one with the pedicels solitary, and this appears 
to be the type of the species ; another with the pedicels in pairs, and also densely clustered or umbellate at 
the tops of the short young branches, but differing from the former in no other respect ; the third has the 
leaves much smaller and rounder than either of the others, and the peduncle solitary. We might have been 
disposed to have sepai’ated these into as many distinct species, but Mr. CoUie, whose notes are before us, calls 
them aU by the manuscript name of 8. incequalis, stating- that their vernacular appellation is Irima; while, 
again Gaudichaud remarks that Rima, Irima, and Ouirima, are all applicable to S. rotundifolia.
