360 BORHAGINACEiE. (BORAGE FAMILY.) 



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

 Greek name, of uncertain origin. ) 



1. B. nigra, L. (Black Horehound.) More or less hairy, but green, 

 erect ; the root perennial ; leaves ovate, toothed ; whorls 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 

 ■Sorolla 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. : anther- 

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

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

 Bhaped, hairy; upper lip of the purple corolla densely bearded with white hairs 

 on the inside. — Shore of Lake Ontario near Rochester. June, July. (Adv. 

 from Eu.) 



Order 72. BOHRAGIMCEJ1. (Borage Family.) 



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

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

 in No. 1), 5 stamens inserted on its tube, a single style and a deeply 4,-lobed 

 ovary (as in Labiatse), which 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 seorpioid), 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. BORRAGE1]. Ovary deeply 4-parted, forming as many separate 1-seeded 

 nutlets in fruit 5 the style rising from the centre between them. (Root frequently red.) 



# Corolla naked aud open (without scales) in the throat, somewhat irregular ! Nutlets erect 



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



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



2. Lycopsis. Corolla funnel-form, slightly curved and oblique : scales blunt and hairy. 



3. Sy cm pliy turn. Corolla tubular, and enlarged at the summit : scales awl-shaped. 



*# * Corolla open, with folds rather than scales in the throat. Nutlets smooth, erect ; scar small 

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



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



6. Litliosuernium. Nutlets stony, smooth. Lobes of the corolla spreading, rounds*-
