(Ammannia humlUSy Mir hx.) — Low or wot groun*!, M;iss. to Fla., west to 

 Ind., Kau., and Tex. — With Ammaiinia-like hahit, an exception in the genus. 



3. AMMANNIA, llou.su.n. 



Flowers in 3 - many-flowered axillary cy ines. Calyx globular or hell-shaped, 

 4-angled, 4-to()thed, usually with a little horn-shaped a])pendage at each sinus. 

 Petals 4 (purplish), small and deciduous, sonu'times wanting. Stamens 4-8. 

 Capsule globular, 2-4-celled, bursting irregularly. — Low and inc(jnspicuous 

 smooth herbs, with opposite narrow leaves, and small flowers in their axils, 

 proauced all summer. (Named after Paul Ammann, a German botanist ante- 

 rior to Linnanis.) 



1. A. eoccinea, liottb. Leaves linear-lanceolate (2-3' long), with a 

 broad auricled sessile base ; cymes subsessile, dense ; petals purplish ; stamens 

 more or less exserted ; style usually slender; capsule included. (A. latifolia, 

 (jiay. Manual, not L.) — N. J, to Fla., west to vS. Ind., Kan., and Tex. The 

 style varies uiuch in length, sometimes in the same specimen. Apparently 

 the more developed form of the southern A. latifolia, Linn., which, as limited 

 by Koehne, has apetalous flowers, with included stamens and short style. 



4. LYTHRXJM, L. Loosestrife. 



Calyx cylindrical, striate, 5-7-toothed, with as many little processes in the 

 sinuses. Petals .5 - 7. Stamens as many as the petals or twice the number, 

 insei'ted low down on the calyx, commonly nearly equal. Capsule oblong, 2- 

 celled. — Slender herbs, with opposite or scattered mostly sessile leaves, and 

 purple (rarely white) flowers; produced in summer. (Name from Kvdpov, 

 blood ; perhaps from the styptic properties of some species.) 



* Stamens and petals 5-7 ; floicers small, solitari/ and nearly sessile in the axils 



of the mostly scattered upper leaves ; proper calyx-teeth often shorter than the 

 intermediate processes ; plants smooth. 



1. L. Hyssopifolia, L. Low annual (6-1 0' high), pale; leaves oblong- 

 linear, obtuse, longer than the inconspicuous flowers ; petals pale-purple ; sta- 

 mens usually 4-G, included. — Marslies, near the coast, Maine to N. J. (Ku.) 



2. L. lineare, L. Stem slender and tall (3-4° high), bushy at top, trilh 

 2 margined am/les ; leaves linear, chiefly opposite ; petals whitish ; flowers with 

 6 included stamens and a short style, or the stamens exserted and style short ; 

 ovary on a thick short stalk; no fleshy hypofjynous ring. — Brackish marshes, 

 N. J. to Fla. and Tex. 



3. L. al^tum, Pursh. Tall and wand-like perennial ; branches irith mar- 

 gined angles; leaves ohiong-ovate to linear-lanreolate, acute, icith a cordate or 

 rounded base, the upper mostly alternate ; calyx 2 - 4" long ; petals rather large, 

 deep-purple; stamens of the short-styled flowers exserted; fleshy hypogyuuus 

 ring prominent. — Ont. to Minn., south to Ga., Ark., and Col. ; also near Boston. 



* * Stamens 12 {rarely 8 or 10), tivice the nund>er of the petals, 6 longer and 6 



shorter; floxvers large, croioded and whorled in an inteirupted spike. 



L. SalicXria, L. (Spiked Tvoosestrife.) More or less downV and tall ; 

 leaves lanceolate, heart-shaped at base, sometimes whorled in threes; rit)wer.s 

 ])urple, trimor])hous in the relative lengths of the stamens and style. — Wet
