Order LXXI. VALERIANACE.E. 



Herbs (rarely suffrnticose) ; with opposite leaves, no stipules, hermaphrodite 

 or sometimes polygamo-dioccious flowers in cymose inflorescence, a 5-merous 

 somewhat irregular epigynous corolla, bearing fewer (1 to 3, rarely 4) stamens 

 on its tube, an ovary invested by the calyx-tube, and of one to three cells, but 

 only one ovuliferous, a solitary suspended seed with a straight embryo and no 

 albumen. Limb of calyx none, or of lobes or teeth, or evolved on the fruit into a 

 kind of pappus. Corolla either obscurely or manifestly irregular (bilabiately, §) ; 

 lobes imbricated in the bud. Filaments and style filiform : stigma undivided and 

 truncate, or minutely 3-cleft. Ovule anatropous. Fruit dry and indehiscent, a 

 kind of akene. 



1. VALERIANA. Calyx-limb of 5 to 15 setiform lobes, which arc inrolled and inconspicu- 

 ous until fruiting, when they .are evolute and form a kind of plumose pappus. Corolla from 

 campanulate-funnelform to salverform, the tube or body often gil)bou3 or slightly saccate 

 anteriorly. Stamens 3. Ovary 1 -celled, and with mere vestiges of two lateral cells, ripen- 

 ing into a flattened akene, which is mostly 1-nerved on one face, 3-nerved on the other, 

 and with a more or less evident nerve at each margin, which marks the position of a sup- 

 pressed empty cell. — Perenuials (with hardly an exception), the roots with a peculiar scent. 



2. VALERIANELLA. Calyx-limb not pappose, in all ours more or less obsolete. Corolla 

 from short-fuunelform to salverform, with or without gibbosity, or sometimes a sac or spur 

 at base ; limb 5-parted, from nearly regular to obscurely or plainly bilabiate, or 4-parted with 

 the posterior lobe notched or 2-cleft. Stamens 3, very rarely 2. Fruit various, the two 

 abortive cells sometimes obsolete and nerviform at the lateral angles, commonly enlarged, 

 sometimes converted into wings. Annuals, with entire or sparingly dentate or incised leaves ; 

 cauline sessile. 



1. VALERIANA, Tourn. (Old herbalist's name, from valeo, to be strong, 

 from use in medicine.) — Herbs (chiefly of northern temperate zone) ; with roots 

 of peculiar scent, various leaves, and white or rose-colored flowers, in terminal 

 cymes, produced in early summer. — L. Gen. 8, in part ; DC. Pi*odr. iv. 632 ; 

 Hoeck in Engler, Bot. Jahrb. iii. 2. 



PhyllActis obovAta, Nutt. Gen. i. 21, is omitted, having been described from a plant of 

 the Upper Missouri, not yet in flower, perhaps an undeveloped V. edulis. 



* Erect from a large fusiform perpendicular stock branching below into deep and thickened roots: 

 leaves thickish, nervosely veined, not serrate. 



V. 6dulis, NcTT. Glabi'ous or glabrate ; the nascent herbage often tomentulose-puberulent, 

 sometimes remaining so on the leaf-margins, a foot or at length 3 feet or more high : radical 

 leaves oblanceolate to spatnlate, tapering into a margined petiole, entire or some sparingly
