usque pinnatifidis v. 3-5-partitis laciniis omnibus linearibus obtusis rnarginibus recurvis supra glaberrimis 

 nitidis subtus sericeis, pedunculis villosis subscapiformibus parce foliosis, floribus plerisque in capitulum 

 globosum congestis, calyce liirsuto, petalis fusco-purpureis dorso sericeis, staminibus 2 filamentis brevibus, 

 stigmate depresso fimbriate, fructu tetragono glabriusculo supra medium spinis suberectis apice glochidiatis

Hab. Strait of Magalliaens ; Port Gregory ; Copt. King. 



Radix lignosa, descendens. Caules 2-3-unciales, vaginis pilosis foliorum tecti. Folia 3-5 unc. longa, petiolis 

 graeilibus subsericeis ; foliolis perplurimis, magnitudine variis, 2 lin. ad i unc. longis. Pedunculi pedales, validi, 

 erecti, foliis 2-3 abbreviatis instructi. Flores parvi. 



This species is so nearly allied in general habit to some states of A. pinnatifida, that I hesitated before sepa- 

 rating them. That plant I find to differ in having the surface of the fruit invariably armed with many and much 

 larger spines. The A. pinnatifida also is a native of Patagonia, having been found by Mi'. Darwin at Port Desire, in 

 fruit only, and his specimens are of a much smaller size than those from Chili, but not otherwise distinct. The pre- 

 sent species connects the Fuaccena with the Ancistrum group, and is, too, the most nearly allied to the following, 

 which, possessing no spines, seta;, or glochidise whatever, will not rank under either of those subgenera.

Hab. Falkland Islands ; very abundant on rocks near the sea. 



Caides elongati, 6 unc. ad pedalem, prostrati, curvati, crassitie pennae anserinae, vestigiis petiolorura delapso- 

 runi vaginati, apicibus ascendentibus. Folia ad apices ramorum conferta, 1-2-polliearia ; petiob basi late vaginantes, 

 vaginas margine ciliata ; foliola pro genere minima, 1 lin. longa, pallide viridia, ad basin in lacinias 3-4 fissa, plus

A plant long known in cultivation in England, but very imperfectly described. I am not aware by whom it 

 was first detected. Vahl describes it from a specimen in the Jussieuan herbarium, and states that he saw it growing 

 in Dr. Pitcaini's garden near London, where the fruit was unarmed ; this is always the case in native specimens, 

 though Vahl asserts the contrary. It is not improbable that some of the varieties of A. trifida, from Patagonia, 

 may have been mistaken for this.
