 1. E. cicutarium. UHerit. — Geranium cicutarium. Linn. 



Hab. Conception. — This and the two Gerania above-mentioned were prohahly introduced with the seeds 

 of European vegetables, and have now become naturalized, We have specimens of them from Mr. Cruck- 

 shanks, Mr. Macrae, and Mr. Bridges. — Nearly allied to this order, and connecting- it with the Oxalidea, 

 but which Mr. Don has referred to Caryophyllece, next to Mollugo, is the genus Viviania of Cavanilles, 

 " Ann. de Cienc. Nat. v. 7. p. 211. t. 49." At the time the account of it was published in the Botanical 

 Miscellany, v. 1. p. 174, under the name of Macrcea, given to it by Mr. Lindley in Brande's Journal of 

 Science, v. 5. p. 104, we were not aware of its being identical with that of Cavanilles, whose name must, of 

 course, be preferred. The same has also been described by Cambessedes, (Mem. du Mus. v. 18. p. 3C9. t. 

 18,) as a new Brazilian genus, and called Casarea. We regret to say that it does not appear to have been 

 gathered by the Naturalists of the Expedition, but we possess specimens of three species from Mr. Cruck- 

 shanks, Mr. Macrae, and Dr. Gillies, from various parts of Chili. A fourth species from Chili ( V. parvi- 

 flora), we have not received : it has, however, been found by Mr. Macrae.

1. OXALIS. Linn. 



1. O. ? glomerata ; acaulis, foliis trifoliolatis, foliolis linearibus, scapo petiolis elongatis 

 duplo longiore, umbella multiflora capitata. 



Hab. Coquimbo. — We have not been able to find more than three calyciue segments to each flower, of 

 an oblong shape, somewhat 3-toothed at the top ; but it must be observed that the specimens are in a very 

 imperfect state. There are 5 yellow petals, about the length of the calyx. The pedicels are bracteated at 

 the base. Stamens 10: Stigmas 5. Pistil as in the genus. 



2. O. carnosa ; herbacea glabra, caule perbrevi dentibus cicatricato, foliolis ternis longe 

 petiolatis obcordatis carnosis subtus punetato-chrystallinis, scapo trifloro, calycis foliolis 

 duobus exterioribus majoribus planis, radice tuberosa. " Molina." — Lindl. in Bot. Reg. 

 t. 1063. Hook, in Bot. Mag. t. 2S66. 



Hab. Conception. — Mr. Collie notices this as a very succulent, acid, and powerfully antiscorbutic plant. 



3. O. laxa ; caule simplici folioso brevi, foliolis 3 late obcordatis supra pauce inferne 

 densius pilosis ciliatis, petiolis pilosis, pedunculis folio duplo longioribus pilosis apice 

 paniculam laxam gerentibus, sepalis pilosis angustissime lanceolatis. 



Hab. Conception. — A small species, with numerous leaves and panicles, which latter exceed the foliage 

 in length. 



4. O. parvifolia ; caulibus ramosis repentibus glabris, ramulis foliosis, pedunculis 

 1-floris, foliolis subrotundo-obovatis emarginato-bilobis ciliatis utrinque adpresso-pilosis, 

 petiolis calycibusque pubescentibus, stylis longissimis. DC. — Humb. et Kunth, Nov. Gen. 

 v. 5. p. 245. De Cancl. Prodr. v. 1. p. 693. 



Hab. Conception. — This is very nearly allied to O. filiformis of Humboldt, if it be not the same. 



5. O. rosea; caule erecto carnoso folioso, pedunculis axillaribus longissimis apice 

 corymboso-racemosis, foliolis obcordatis.
