TRELEASE — A REVISION OF N. AM. LINACE.E. I3 



the inner scarious-margined, sometimes erose but not ciliate, more or 

 less 3-5-keeIed below; petals 15-20 mm. long, thrice the length of the 

 calyx; stamens equal to or twice as long as the sepals, appendages slen- 

 der; pistil once to twice the length of the stamens ; stigmas short, not 

 more than twice as long as broad; capsule 2 or 3 times as long as the 

 caljx, ovoid, obtuse, incompletely lo-celled and lo-valved, the valves 

 dehiscing widely above and separating through the partitions nearly to 

 the center below, the septa ciliate. — Alaska to Saskatchewan and the 

 Great Plains, south to Arkansas and Texas. 



The aspect of this species is subject to much variation, the shorter, 

 more cespitose plants usually having more crowded and narrower leaves 

 than the taller forms. If the Siberian form oi L. fere?i?ie agrees with the 

 European in having heterogone flowers, our plant must stand as distinct, 

 otherwise it may bear Eaton and Wright's name. The Asiatic material 

 at my command is too limited to decide this point. 



* * Estipulate or with stipular glands ; pedicels usually short; flowers small or medium 

 sized, yellow; sepals more or less glandular-ciliate or serrulate, persistent or 

 deciduous: filaments without intervening appendages ; carpels J, sometimes with 

 cartilaginous insertions at base ; styles distinct or united; stigmas capitate; capsule 

 witli firm septa, the false septa sometimes membranous toward the inner margin or 

 incomplete and ciliate. — § Linastrum . 



2. L. Flokidanum. L. Vtrgi'nianum, var. } Floridanum, Planch. I.e. 

 vii. 480. L. Virgin I'a/ium, in part, of Chapman. — Perennial, glabrous, 

 ii-2 feet high ; stems several from the same root, erect, simple below, 

 terete and striate or the branches slightly angled ; leaves remote or some- 

 what approximated, the lowest pair or two usually opposite, oblong or 

 oblong-lanceolate, mostly acute, i-nerved (1-5 X 10-20 mm.), without 

 stipular glands ; flowering branches mostly few, ascending or recurving, 

 with rather few sometimes secund flowers, not very leafy ; sepals ovate, 

 taper-pointed, keeled, the inner edges glanduliferous ; petals spatulate- 

 obovate, 5-6 mm. long, about twice the length of the calyx; stamens and 

 pistil about equal to the calyx, intervening appendages reduced to mere 

 thickenings of the membrane; capsule ovoid, about 3 mm. long, equaling 

 or exceeding the calyx, essentially lo-celled, with firm septa. — Florida to 

 Louisiana. Well represented in Curtiss's North American Plants, No. 

 412, from the dry pine barrens of Duval Co., Florida. I also refer here a 

 large-fruited plant labeled from Illinois, in Hb. Gray, without date or 

 name of collector. 



3. L. ViRGiNiANUM, L. Spec. 279. — Similar to the last, but more loosely 

 branched, the flowering branches recurved- spreading or corymbose; 

 capsule depressed-globose, very obtuse, about 2 mm. long. — Dr ysoil 

 from Canada to Texas. A variable plant, of which Planchon recognizes 

 several varieties.
