Hab. North-West Coast of America. Nelson in Herb. Banks, {Pursh,) Chamisso's Island and Island 

 of St. Lawrence. Chamisso. — I have placed this next to A. arctica, because, judging from Pnrsh's descrip- 

 tion, it must be nearly allied to it. Chamisso, however, keeps it distinct; but says, that in the Bay of St 

 Lawrence (on the Asiatic side of Behriug*s Straits) ho found a plftnt that Avas intermediate between 

 the two in question. The chief distinction from A. ajctica, appears to me to be in the capsule, which Pursh 

 says is thrice as long as the calyx. 



14. A, fasciculata ; Q) " glabriuscula, caespitosa, cauliculis stricto-erectis, foliis subii- 

 latis pungciitibus striatis, floribus dense fasclculatis, calyclbus subulatls striatis, petalis 

 brevissiniis." — Pursli, FL Am, v, 1. p, 319. 



Hab. Canada; in Mr. Lambert's Herbarium from Kew Gardens. {Pursk.) — This plant must be con- 

 sidered very doubtful. The true A. fasciculata of Gouan is perhaps one of the rarest of all plants. His 

 Herbarium in my possession proves it to be quite distinct from the plant so named and figured by Jacquin, 

 {Anstr.p. 182,) which is the A.fastigiata of Smitb. The Canadian plant Mr. Pursh alludes to, can scarcely 

 be the following, which indeed comes nearer to the true A. fasciculata than any other species, inhabiting, 

 however, a widely different part of America, which was a terra incognita at the time Mr. Pursh wrote. 



15. A, Franklinii; ramis erectis fastigiatis numcrosis fragilihus, foliis nitidissimis siibu- 

 lato-setaceis, floribus fasciculatis, sepalis subulatis scariosis late uninerviis petala lineari- 

 oblonga superaiitibus. (Tab. XXXV.) — A. Franklinii. Douglas^ MSS. 



Radix sublonga, descendens, perennis. Caules breves, foliorum vetustorum vestigiis obsiti, in raraos nu- 

 merosos, erectos, subpalmares, basin versus divisi. JRami valde fragiles, glabri. Folia opposita, basi connata, 

 vix unciam longa, subulato-setacea, erecta, nitidissima, albescentia, obscure uninervia, integerrima vel sub 

 summa lente minute ciliato-dentata. Flores terminales, dense fastigiati. Peduncull breves, foliosi seu bracteati. 

 Bracteoi foliis similes, sed paulo minores magisque scariosw. Sepala semiunciam longa, subulata seu lanceolato- 

 subulata, acuminatissima, membranacea, scariosa, albida, dorso nervo latiusculo obscure viridi notata, margin© 

 nunc integerrima, nunc, ut in foliis, minutissime ciliata. Petala oblonga, obtusissima, basi attenuata, calyce 

 breviora. Stam. 10, vix petala »quantia. Gennen ovale, Styli 3. Capsula ovali-rotundata, calyce multo 

 brevior, apice 3-valvis, valvis medio bihdis. 



Hab. Abundant on barren sandy plains and undulating grounds of the Columbia, from the " Grew/" to 

 the " Kettle Falls;" and south of that river as far as the source of the Missouri. J>om^^.— This is the most 

 beautiful, and, at the same tune, the most distinct of the genus, remarkable for ite fragile stems, and glossy 

 foliage and calyces. Its nearest affinity is assuredly the A. fasciculata of Gouan; but that is at once 

 recognized by its decidedly annual root, its coarser, rigid, and more opaque aspect, and, above all, by the 

 leaves and sepals being strongly 3- or 5-ribbed.
