length, and two of the stamens are equally united, one on each side the vexillum, with these combined 

 claws. The other eight stamens are free. The germen is linear, glabrous ; the style filiform and much curved. 

 In our A. papposa, the base of the limb of the vexillum has a tuft of hairs, and the upper teeth of the 

 calyx are remarkably short. 



2. A. microphylla ; caule fruticoso ramosissimo, ramulis striatis pubescentibus divari- 

 cato-spinescentibus, foliolis minimis 6-jugis orbicularibus brevissime petiolulatis pubes- 

 centibus, racemis subcapitatis terminalibus simplicibus spinescentibus, bracteis orbiculari- 

 bus, leguminibus triarticulatis, setis longissimis plumosis basi rigidiusculis nudis. (Tab. IX.) 



Frutex decumbens, valde dichotomeque ramosus, ramis divaricatis, striatis, spinescentibus, tuberculiferis, 

 tuberculis squamosis (e stipulis vetustis, persistentibus), foliiferis. Folia pari-pinnata, subcarnosa, pubescen- 

 tia, foliolis minutissimis subsexjugis, oppositis, remotis, brevissime petiolulatis, cito deciduis. Stipulm duae, 

 parv«, ovate, in imam bifidam concrete, persistentes. Racemi terminates, 6-8-flori, subcapital, rachi demum 

 spinescente. Bractea parva, subrotunda. Pedicelli semiunciam longi. Calyx campanulatus, breviter 5- 

 dentatus, pubescens. Petala staminaque libera. Alee extus transversim rugosse. Legumen triarticulatum, 

 articulis semiorbiculatis, setis longissimis, flexuosis, plumosis, basi nudis, rigidiusculis dense tectis. 



Hab. Valparaiso. — This and the following species belong to a groupe of Adesmia hitherto undescribed, 

 having fruticose, spinescent stems, and small rigid and somewhat fleshy leaves, a plumoso-setose fruit, and 

 free stamens and petals ; of which several have been collected in Chili and Mendoza by Dr. Gillies and 

 Mr. Cruckshanks. The present species was first detected by Mr. Menzies, whose specimens we possess. It 

 has also been gathered by Mr. Macrae.

3. A. glutinosa; caule fruticoso ramoso, ramulis patentibus glanduloso-hirsutis glutinosis 

 spinescentibus, foliolis subtrijugis ellipticis hirsutis, racemis elongatis terminalibus simpli- 

 cibus spinescentibus bracteisque linearibus glanduloso-hirsutis, leguminibus triarticulatis 

 longissime setoso-plumosis. 



Hab. Coquimbo. — This differs from the preceding in its larger leaflets, longer racemes, narrower 

 bractese, longer pedicels, and in the viscid glands and patent hairs which clothe all the younger parts of the 

 plant except the corolla. — The genus Adesmia has been divided by De Candolle into two sections ; the one 

 Patagonium, characterised by the pods of from 4 to 8 joints, and either scabrous or puberulous : the other, 

 Chwtotricha, having a pod of 2 joints, wrinkled, and bearing plumose sete. He even thinks the latter 

 ought to form a distinct genus. We, however, possess some that cannot be referred to either section, but are 

 intermediate ; nor do we think the arrangement otherwise a natural one : we prefer, therefore, the subjoined 

 division, and will notice some other species not in the collection, but which we have received from Chili.*
