the corolla, approximate in pairs. Otherwise much as in Marrubium. (The 

 Greek name, of uncertain origin. ) 



1. B. NIGRA, L. (Black Hoeehound.) More or less hairy, but green, 

 erect ; the root perennial ; leaves ovate, toothed ; vi'horls many-flowered, dense ; 

 calyx-teeth 5, longer than the tube of the purplish corolla. — Waste places, Mas- 

 sachusetts and Connecticut : scarce. (Adv. from Eu.) 



33. PHLOMIS, L. Jerusalem Sage. 



Calyx tubular, 5- 10-ribbed, truncate or equally 5-toothed. Upper lip of the 

 corolla arched ; the lower spreading, 3-cleft. Stamens 4, ascending and approx- 

 imate in pairs under the upper lip ; the filaments of the upper pair with an awl- 

 shaped appendage at the base, longer than the others in P. tuberosa, &c. ; auther- 

 cells divergent and confluent. — Leaves rugose. Whorls dense and many-flow- 

 ered, axillary, remote, bracted. (An old Greek name of a woolly species, of 

 obscure derivation.) 



1. P. tueer6sa, L. Tall perennial (3°-5°high), nearly smooth; leaves 

 ovate-heart-shaped, crenate, petioled ; the floral oblong-lanceolate ; bracts awl-

Order 72. BORRAGHNACEjE. (Borage Family.) 



Chiefly rough-hairy herbs (not aromatic'), with alternate entire leaves, and 

 symmetrical flowers with a 5-parted calyx, a regular 5-lobed corolla (except 

 in No. 1), 5 stamens inserted on its tube, a single style and a deeply i-lobed 

 ovary (as in Labi'ataa), lohich forms in fruit 4 seed-like nutlets, each with a 

 single seed. — Albumen none. Cotyledons plano-convex : radicle pointing 

 to the apex of the fruit. Stigmas 1 or 2. Calyx valvate, the corolla im- 

 bricated (in Myosotis convolute) in the bud. Flowers mostly on one side 

 of the branches of a reduced cyme, imitating a spike or raceme, which is 

 rolled up from the end, and straightens as the blossoms expand (circinate 

 or scorpioid), often bractless. (A rather large family of innocent, muci- 

 laginous, and slightly bitter plants; the roots of some species yielding a 

 red dye.) 



Tribe I. BORRAGE^. Ovary deeply 4-parted, fonning as many Beparate 1-seeded 



nutlets in fruit ; the style rising from the centre between them. (Root frequently red.) 



* Corolla naked and open (mthout scales) in the throat, somewhat irregular ! Nutlets erect 



1. Bchiuiu. Corolla funnel-form, unequally 5-lobed. Stamens protruded. 



» « Corolla with 5 scales closing the throat. Nutlets not prickly, erect ; the scar broad. 



2. liycopsls. Corolla tunnel-form, slightly curved and oblique : scales blunt and hairy. 



3. Symphytum. Corolla tubular, and enlarged at the summit ; scales awl-shapetl. 



* » » Corolla open, with folds rather than scales in the throat 'Nutlets smooth, erect ; soar small. 

 ^- Lobes of the tubular corolla imbricated in the bud. 



4. Onosmodlum. Nutlets stony, smooth. Lobes of the corolla acute and erect. 



6. L.ltli08permum. Nutlets stony, smooth. Lobes of the corolla spreading, rounded.
