2. S. asper, Villars. T.ikn tlio preceding or tailor : leaves more strongly and 

 rigi<lly spiny-tcjotlied, and the auricles of the clasping base rounded : pedicels more 

 commonly glandidar-bristly : akenes sharp-edged, smooth. 



Waste places, not only around towns but also far in the interior. 



3. S. tenerrimus, r>inn. Slender : leaves pitmately parted, mainly into linear 

 or narrowly lanceolate divisions, merely 8[»inulose dcnticnlato along the margins : 

 heads rather few: akenes narrow and thickish, rugose scabrous. — Ton. & Gray,

Order LII. LOBELIACE^. 



Herbs, mostly with milky juice, alternate simple leaves, and scattered or race- 



raose flowers, tho calyx adnato to the whole or tho lower half of the ovary, and 



Rtamojia usually free from tho corolla; distinguished from Campanulacfrv (to Avhich 



tho order is now commonly reduced) by tho irregular corolla and both monadol- 



phous and (usually) syngenesious stamens. — Flowers perfect. Limb of tho calyx 



divided down to the ovary into 5 lobes. Corolla inserted just where the calyx 



separates from the ovary, variously lobcd or cleft ; the lobes valvate or lightly 



imbricated in the bud, two of them usually different from the others in size or 



shape and union, so that the limb appears bilabiate. Stamens 5, alternate with the 



lobes of the corolla : filaments united into a tube above the base and commonly to 



the top ; anthers 2-celled, introrsely dehiscent, firmly united into a ring, e.xcept in 



the anomalous Nemacladus. Ovary 2-celled with axile, or 1-celled with parietal 



placentae : ovules numerous, anatropous : style entire : stigma commonly 2-lobed 



and girt with a ring of hairs. Fruit in ours a many-seeded capsule. Embryo small 



in the axis of fleshy albumen. Juico more or less acrid. 



The large and widely distributed penus Lohrlia (of almnt 200 sporics) is strangely absent from

TuiBK I. LOBEIJE/E. Anthers ns well as filaments united around the style. Corolla as it 

 were 2-lippcd, two of the lobes smaller and more separated from the other united three, 

 erect or divergent. 



1. Laurentia. Corolla with a rather long entire tube. Capsule 2-vnlved across the top. 



2. Downingla. Corolla with very short entire tube. Capsule linear and elongated, opening 



down the sides by one to three long fissures, one-celled. 



TninE II. CYPHIE/E. Anthers separate, and filaments jiartly so. 



3. Nemacladus. Corolla narrow : one lip of two almost distinct jK-tals, the other of three more 



united ones. Capsule 2-vnlved at tho top. 



1. LAURENTIA, Micheli. 

 Calyx-tube and adnate ovary top-shaped or oblong ; the T) lubes nnrmw. Corolla 

 with tube as long as the limb, not split down ; its lai-ger nud 3-cleft lip widely 

 spreading; tho smaller of 2 moro erect or diverging divisions. Filaments and 

 anthers completely united ; two of tho latter miinitoly bristle-tufted at tho oi)CX, 

 nearly included. Stigma moro or less 2-lobed. Capside 2-valved across tho pro- 

 jerting free apex, 2-celled. Seeds oblong or almost fusifnrm. — Low and dilTusc or
