The styles are trigonous, straight, compressed, the angles more or less produced downwards, upon the body of 

 the carpel, which is hence sometimes ribbed. 



4. Ranunculus plebeius, Br. 



Asa Gray (Bot. U. S. Expl. Exped. p. 8) doubts this plant being the same as Brown's New Holland one, and 

 the question, on re-examination, appears to me still open to doubt ; though, after a long and careful study, I can 

 find no characters to distinguish it beyond those indicated, and a more slender habit. 



5. Ranunculus hirlus, Banks et Sol. 



Asa Gray (Bot. U. S. Expl. Exped. p. 7) says that he should have supposed this to be the R. acris of Kichard 

 and Cunningham, but for my quoting that name under R. plebeius. There is no mistake in my reference, though 

 there may possibly have been a transposition of tickets in A. Cunningham's Herbarium ; but this question can never 

 be settled. Dr. Monro has sent it from Wakefield, in the Middle Island. 



6. Ranunculus multiscajous, Hook. fil. 



Dr. Monro sends a large state of this from Aglionby Plains, with broad trifid or three-lobed leaves, and flowers 

 -| inch in diameter, in both single and many flowered scapes. 



7. Ranunculus incisus, Hook. fil. 



Numerous additional specimens of this plant do not resolve my doubts as to its specific distinctness from R. 

 rwularis, of which it may be a terrestrial state ; the styles of the achenia are, however, much longer. I have spe- 

 cimens from marshes in South Australia (Melbourne), gathered by F. Adamson, Esq.

 Pod as in Cardamine, but with a more evident midrib on each valve. 



Arabis ? fastigiata, Hook. fil. ; glaberrima, caulibus e rhizomate elongato robusto vestigiis foliorum

 lineari- v. lanceolato-spathulatis obtusis acutisve grosse serratis petiolo lato, caulinis linearibus subserratis, 

 floribus subcorymbosis albis, sepalis oblongis obtusis pedicello brevioribus, petalis obovato-spathulatis longe 

 unguiculatis sepalis duplo longioribus, filamentis gracilibus, antheris late oblongis, stylo brevi, stigmate 

 capitato, siliqua gracili lineari acuminata stylo brevi stigmateque obtuso terminata, seminibus elongato-

Hab. Middle Island : highest part of M'Crae's Run, on rocks, Monro. 



A very remarkable plant, resembling in habit the Cardamine radicata (Hook. fil. Ic. Plant, t. 882) of the Tas- 

 manian mountains. Owing to the immaturity of the pod, the genus is doubtful ; but as the southern forms of Car- 

 damine and of Arabis (to one of which it belongs) are hardly generically distinct, this point is of less consequence. 

 The discoverer says that only three or four specimens were seen, growing out of a rock, and that they had a strong 

 odour of turnips. — Rhizome 2-4 inches long, as thick as the little finger, spongy, covered with the spreading squar- 

 rose old persistent petioles. Branches very many, ten and more, from the summit of the rhizome, strict, erect, or 

 spreading a little, leafy, all flowering, a span long, slender, some simple, others a little branched. Radical leaves 

 1-3 inches long, +~| inch broad, thick, rather fleshy, narrow, linear-spatlmlate or lanceolate, sharp or blunt, coarsely 

 serrate, on broad petioles ; eauline leaves smaller, less toothed or quite entire. Floivers white, in many-flowered 

 corymbs, on slender pedicels. Sepals pale green, nerved, oblong, blunt. Petals \ inch long, spathulate, on long 

 claws, white, blunt. Stamens with slender filaments and broad anthers. Pods suberect, thirty to forty on each
