Since the preceding observations were written, I have seen in Sir William Hooker’s Herbarium, two specimens of a Clianthus, found by Mr. Bynoe, on the North-west coast of Australia, in the voyage of the Beagle.  These specimens, I have no doubt, are identical with Dampier’s plant, and they agree both in the form of leaves and in their subumbellate inflorescence with the plant of the Lachlan, Darling, and the Gawler Range.  From the form of the half-ripe pods of one of these specimens, I am inclined to believe that this plant, at present referred to Clianthus will, when its ripe pods are known, prove to be sufficiently different from the original New Zealand species to form a distinct genus, to which, if such should be the case, the generic name Eremocharis may be given, as it is one of the greatest ornaments of the desert regions of the interior of Australia, as well as of the sterile islands of the North west coast.

CLIDANTHERA.

Char.  Gen.—­Calyx 5-fidus.  Petala longitudine subaequalia.  Stamina diadelpha:  antheroe uniformes; loculis apice confluentibus, valvula contraria ab apice ad basin separanti dehiscentes!  Ovarium monospermum.  Stylus subulatus.  Stigma obtusum.  Legumen ovatum, lenticulari-compressum, echinatum.

Herba, v.  Suffrutex, glabra, glandulosa; ramulis angulatis.  Folia cum impari pinnata; foliolis oppositis, subtus glandulosis.  Stipulae parvoe, basi petioli adnatoe.  Flores spicati, parvi, albicantes.

OBS.  Subgenus forsan Psoraleae, cui habitu simile, foliis calycibusque pariter glandulosis; diversum dehiscentia insolita antherarum!

6.  CLIDANTHERA psoralioides.

LOC.  Suffrutex bipedalis in paludosis.  D. Sturt.

DESC.  Herba, vel suffrutex, erecta, bipedalis, glabriuscula.  Ramuli angulati.  Folia cum impari pinnata, 4-5-juga; foliola opposita, lanceolata, subtus glandulis crebris parvis manifestis, marginibus scabris.  Spicae densae, multiflorae.  Calyx 5-fidus, parum inaequalis, acutus, extus glandulis dense conspersus.  Corolla:  Vexillum lamina oblonga subconduplicata nec explanata, basi simplici absque auriculis; ungue abbreviato.  Aloe vexillo paulo breviores, carinam aequantes, laminis oblongis, auriculo baseos brevi.  Carinoe petala alis conformes.  Stamina diadelpha, simplex et novemfidum; antherae subrotundae v. reniformes, valvula ventrali anthera dimidio minore subrotunda.  Ovarium hispidum ovulo reniformi.  Legumen basi calyce subemarcido cinctum, echinatum.  Semen reniforme, absque strophiola; integumento duplici.  Embryo viridis; cotyledones obovatae, accumbentes.

OBS.  This plant, which in some respects resembles certain species of Glycyrrhiza, appears to be not unfrequent in the southern interior.  It was found in one of the early expeditions of Sir Thomas Mitchell, and Mrs. (Capt.) Grey, observed it on the flats of the Murray.

7.  Swainsona (grandiflora) suffruticosa pubescens, foliis 8-10-jugis inexpansis incano-tomentosis; foliolis oblongis obtusis retusisve:  adultis semiglabratis:  rachi subincana, racemo multifloro folium superante, bracteolis lanceato-linearibus acutis aequantibus tubum calycis albo lanati quinque fidi:  laciniis acutissimis longitudine fere tubi, vexillo bicalloso.
