Dr. Maximowicz, of St. Petersburg, in his recent " Adnotationes de Spirteaceis" (Act. Hort. 

 Petrop. vi. 105-261), separates from the order Rosacece the tribes Spirccca; and Quillajrie, of 

 which together with the Pomcte he forms an order Poinacece, intermediate between the llosaccui 

 proper and the Saxifragacece-. This new order is distinguished from the first chieHy by the dehis- 

 cent carpels or by the carpels connate with the calyx, and from the last bj' the indefinite stamens 

 in alternating whorls, the outer the longest. The genus Spircca itself, as ordinarily understood, 

 is resolved by him into several distinct genera, and the American species whicli have been referred 

 to Ncillia are also made to constitute a new genus, Physocarpus. While not jjrepared to adopt 

 all of the proposed changes, some of them at least appear judicious. The following synopsis shows 

 the alterations made by him in the ai'rangement of our species. 



* Carpels alternate with the calyx-lobes when of tlie .same number. 



-f- Seeds with membranaceous testa and no albumen : stipules none. 



++ Calyx persistent in fruit : stamens perigynous : carpels several-seeded. 



3. Spiraea, Linn. Carpels cartilaginous, 1-valved, distinct. Flowers perfect, rarely polyga- 



mous. Leaves simple, serrate or incised. — S. betul^folia, S. Douglasii, and S. 



C^SPITOSA. 



3^ Eriogynia, Hook. Cai-pels membranaceous, 2-valved, distinct. Flowers perfect. Leaves 

 biternately parted. — E. PECTINATA, Hook. (Spirceapedmata, Torr. & Gray). Collected 

 on Mount Shasta, Hooker k Gray. 

 ++ ++ Calyx marcescent in fruit : stamens hypogynous : carpels few-seeded. 



S^ Aruncus, Linn. Carpels cartilaginous, 1-valved, distinct. Flowers dioecious. Leaves re- 

 peatedly ternately divided. — A. sylvester, Kost. {Spiroia Aruncus, Linn.) 



-i- -i- Seeds with shining stony testa : albumen very distinct : stipules membranaceous, caducous. 



4. Physocarpus, Maxim. Follicles membranaceous, inflated, 2-valved, distinct, often stiiti- 



tate. Flowers perfect, corymbose. Leaves lobed. — P. opul(FOLIA, Maxim., P. ToR- 

 REYi, Maxim. {Neillia opuUfolia, Benth. & Hook., and N. Torrcyi, Watson.) 

 * * Carpels opposite to the calyx-lobes when of the same number, 



4*, Chamaebatiaria, Maxim. Follicles coriaceous, 1-valved, connate at base, several-seeded. 

 Albumen distinct. Flowers perfect. Leaves small, coriaceous, stipulate, bipinnately 

 dissected. — C. Millefolium, Maxim. (Spira:a JUillefolium, Torr.) 

 * * * Carpel becoming an akene. ( Excluded from Pomwcaf. ) 



4''. Holodiscus, Maxim. Carpels alternate with the calyx-lobes, with densely silky styles, 

 and 2 collateral pendulous ovules. Akenes membranaceous, woolly, 1-seeded. Leaves 

 lobed, without stijiules. — H. discoi,or, Maxim. (Spirtea discolor, Pursh.) Maxi- 

 mowicz considers this genus to be most nearly allied to Cercocarpus, etc.
