NORTH AMERICAN GERANIACEAE. 77 



foliage of Carolinianum. I have seen only a few plants, of a single collection, and have 

 looked in vain for other characters by which this form can be separated, althongh the 

 seeds indicate more than a varietal difference. — PL 12, fijr- 8. 



Var. LOXGiPES, "Watson, King's Eep., v, 50, of the monntains of Colorado and Utah, 

 differs from the type in being of looser growth, with longer spreading peduncles and 

 pedicels. 



Bentham, in some instructive remarks on this species in Flora Australiensis, i, 296 

 regards it as only a form of the next, with which it certainly has much in common. "While 

 our plant is sepai-atcd from the European dissectuin without much difficulty, it must be 

 admitted that Australian specimens are identical with those from the United States, with 

 the exception that their clusters of fruit are mostly less dense and their roots perennial. 

 Baron von Mueller, who for a time agreed with Bentham in referring the Australian 

 form to dissectum, and oncc^ called it Caroliuiamuu, writes me that he has now adoiJted 

 the name G. jn^osimi for it. 



G. DissECTUM, L. Amoen., iv, 282. G. Carolinianum, Gray, Proc. Am. Acad., vrri, 

 378. Very similar to the preceding, but the leaves rather more remote below, and, like 

 the small i)ale flowers, clustered at the ends of the branches, their lobes longer and nar- 

 rower; seed closely and rather deeply pitted. — Introduced into various places from 

 Europe. I have seen specimens only from Oregon {Hall, 72) and "Washington Terri- 

 tory (SnJcsdoiif), but it is reported from various localities. Most of what has passed in 

 America for this species is G. Carolinianum. Small specimens, like those of Hall, have 

 much the habit of G. j^usillum, but are distinguished by the seed. — PI. 9, fig. 15. 



G. KOTUNDiFOLiUM, L. Spcc, G83, from Europe, resembling G. Carolialanum in its 

 fruit and seed, and of nearly the habit of G. jmsilhtm, but with the leaves short-lobed 

 and the stem, etc., villous with long white hairs tijiped with purple glands, has been 

 collected in Michigan (Farwell) and on ballast about New York city (Brown). — PI. 9 

 fig. 16; 10, fig. 9; 12, fig. 4. 



9. G. PUSiLLUM, L. Spec, 2 ed., 957. Slender-stemmed, spreading, soft-pubescent, or 

 the calyx, etc., villous and usually glandular; branches leafy; leaves small, round-reni- 

 form or the cauline truncate at base, equally cleft into nine oblong or linear lobes each 

 more or less regularly 3-toothed at apex; peduncles frequently opposite the leaves, short, 

 like the pedicels; sepals ovate, acute or acuminate, not awned; petals pale purple, about 

 equalling the calyx; fruit very small; beak about 10mm. long, short-pointed, puberulent* 

 styles free for about 1 mm.; divisions of ovary 1 x 2mm., finely canescent, keeled, not 

 wrinkled; seeds 5 x 1.4mm., smooth. — Open places, New Yoi-k and Pennsylvania to 

 Ohio; also reported from Canada (Macoun, Cat. irr, 502) ; introduced fi-om Europe. 

 Five of the filaments are said to be constantly without anthers, as in Erodiiim. — PI. 9 

 fig. 14; 10, fig. 3; 12, fig. 10. 



G. MOLLE, L. Spec, 682, a very similar European plant, but readily distinguished by 

 its dark flowers with ten antheriferous stamens, glabrous transversely wrinkled carpels, 

 slightly striate seed, and longer soft pubescence, has been introduced in New York 

 {Saiiwell, Kniesl-ern) , Ohio (Werner), "Washington Territory (Suksdorf) and Van- 

 couver Island (Macoun) ; it is also reported in Ontario {Macoun, Cat., m, 502), and has
