Polygala.] POLYGALE^J. 51 



sepals petals and capsules not ciliate, large sepals oblong-obovate broader 

 than the capsule. Common; ascends to near 3,000 ft. ia the Highlands. — 

 Var. grandifio'ra, Bab.; upper leaves large, inner sepals oblong acute, 

 flowers large dark blue. Benbulben, Sligo. 



Sub-sp. P. oxyp'tera, Eeichb. ; branches flexuous, leaves linear, inner sepals 

 cuneate below shorter and narrower than the capsule, pedicels &c. glabrous. 

 — Sandy shores, limestones and chalky soils, from Perth southd. ; local. 



Sub-sp. P. dkprks'sa, Wend. ; stems flexuous, leaves somewhat opposite and 

 distichous, lower oblong spathulate, racemes fewer-flowered, bract shorter 

 than the flowering pedicel. P. serpylla'cea, Weihe.-- Common on heaths. — 

 Var. P. cilia'ta, Lebel ; branches prostrate tortuous, inner sepals broader 

 than the capsule, pedicels bracts sepals and capsule ciliate. Gogmagog 

 Hills. 



2. P. calca'rea, F. Schultz ; branches many rooting and proliferous 

 umbellately spreading from the root, radical leaves rosulate, cauline 

 oblong, inner sepals longer and broader than the obcordate capsule, central 

 nerve branching above the middle. P. ama'ra, Don, not L. 



Dry soil and rocks, S. and S.E. of England ; "Wiltshire to Kent, and Gloucester 

 to Berks ; Channel Islands ; fl. June-July. — Perhaps only a sub-species of 

 P. vulga'ris, approaching sub-sp. depres'sa, but the habit is entirely different, 

 and the nerves of the sepals scarcely anastomose. — Distrib. Central and S. 

 Europe. 



3. P. ama'ra, L. ; leaves rosulate spathulate, flowering branches 

 axillary, inner sepals narrower than the capsule, nerves simple or slightly 

 branched free, capsule orbicular notched. 



Very rare, margins of rills, in Teesdale, alt. 1,800 ft.; Wye Down, Kent; fl. 

 June-July. — Much smaller in all its parts than P. vulga'ris or calca'rea, and 

 readily distinguished by this character and the narrow inner sepals. The 

 Teesdale form (P. uligino'sa, Fries) is rather more fleshy and has rosy 

 flowers ; the Kent form (P. austri'aca, Crantz) is blue flowered. I find no 

 difference between their capsules. It is certainly the P. ama'ra of Linn. 

 Herb. — Distrib. Europe (Arctic) from Sweden southd. 



ORDER XI. FRANKENIACE2E. 



Perennial rarely annual herbs or small shrubs, with jointed branches. 

 Leaves small, opposite, exstipulate. Flowers small, regular, solitary, in 

 the forks of the branches. Calyx tubular, persistent ; lobes 4-6, in- 

 duplicate in bud. Petals 4-6, hypogynous, imbricate in bud, claw with 

 an adnate scale. Stamens 4 or more, separate or connate at the base ; 

 anthers versatile. Disk 0. Ovary free, sessile, 1-celled ; style slender, 

 stigma 2-5-lobed ; ovules many, in 2 series, on 2-5 parietal placentas, 

 amphitropous with the micropyle below ; funicle slender. Capsule en- 

 closed in the persistent calyx, 3-5-valved. Seeds oblong, raphe linear, 

 testa crustaceous, albumen mealy ; embryo axile, straight. — Distrib. 

 Temp, and warm regions, chiefly littoral ; species about 12. — Affinities 

 with Caryophyl'lece and Tamariscine'ce. — Properties none.
