II. PRIMULA, PRIMROSE. 



Calyx tubular, decidedly angled, 6-cleft. Corolla more or 

 less salver-shaped, with the tube widened above the insertion 

 of the stamens (Fig. 157) ; the 6 lobes of the limb often 

 notched or cleft. Stamens 5, not protruding outside the 

 corolla-tube. Capsule egg-shaped, splitting at the top into 

 5 valves, each of which may divide in halves. Low perennial 

 herbs, with much veined root-leaves ; scapes each bearing an 

 umbel of flowers, which are often showy. 



(P. GRANDiFLOK.i), Trde Primrose. Leaves spatulate or 

 obovate-oblong. Flowers rising on separate slender pedicels from 

 the leaf-axils, corolla originally pale yellow, liut varying to white, 

 red, and many intermediate shades, with a broad, flat limb. Culti- 

 vated from Europe. 



in. LYSIMACHIA, LOOSESTRIFE. 



Calyx 5-6-parted. Corolla wheel-shaped, with its divisions 

 commonly nearly separate. Stamens generally somewhat 

 monadelphous at the base. Perennials with opposite or 

 whorled entire leaves, which are often dotted. 



a. (L. quadrifolia), Four-leaa'ed Loosestrife. Stem erect 

 and simple, 1-2 ft. high, hairy ; leaves whorled, most frequently in 

 fours, broadly lanceolate ; flowers small, axillary, and solitary, on 

 long and slender peduncles. 



b. (L. stricta), Bulb-bearixg Loosestrife. Stems 1-2 ft. 

 high, finally branching, frequently producing bulblets in the leaf-axils 

 after flowering ; leaves abundant, generally opposite, narrowly lance- 

 olate ; the small flowers pedicelled, in a long terminal raceme. 



BORRAGINACEJE, BOR.VGE FASIILY. 



Mostly herbs, with stems and foliage roughened with stiff 

 hairs, with leaves alternate and entire, and symmetrical 

 flowers, generally in a coiled inflorescence. Calyx 5-parted.

 on the corolla-tube. Style one; ovary commonly 4-lobed,
