Tubers may be kept indoors over winter, or species 

 propagated by seeds sown in greenhouse in January. 



6. t6nera, Spreng. ( V. pulcMlla, Sw., not Hort.). 

 Herbaceous perennial: stems cespitose, decumbent, 

 rooting; branches slender, 4-angled, ascending, sparsely 

 hairy: Ivs. decurrent into the short petiole, 3-parted 

 and again pinnatifld into acute, linear, entire, subrevo- 

 lute divisions, sprinkled with short hairs: spikes ter- 

 minal pedunculate: calyx elongated, strigose pubescent 

 or hairy, sprinkled at angles with short stipitate patella- 

 form glands, twice as long as bracts; corolla rose-violet; 

 anther appendages barely exserted, claviculate, subre- 

 curved. Southern Brazil and LaPlata region. 



7. eriuoides, Lam. ( V. multifida, Ruiz and Pav. V. 

 pulchtlla, Hort., in part). Moss VERBENA. Annual 

 or perennial: stem strigose hairy or somewhat hirsute, 

 branching, decumbent, rooting: branches ascending: 

 Ivs. ovate in outline, cuneate base decurrent into the 

 petiole, deeply 3-parted and the divisions pinnatifid 

 into narrow linear acute lobes, subrevolute on mar- 

 gins, strigose especially on nerves: spikes terminal, 

 solitary, pedunculate, soon elongating and relaxing, 

 canescent hairy: bracts lanceolate, acuminate, spread- 

 ing, one-half as long to as long or longer than the calyx; 

 corolla rather small, shortly exserted, lilac, bearded 

 within; anther appendages exserted, rather short. 

 Said by Dr. Gillies to be "one of the commonest plants 

 on the Alps of Clile and Mendoza . . . varying ex- 

 tremely in color of flowers, in stature and in degree in 

 which the leaves are cut." In some individuals the fls. 

 are said to be scarlet, in others blue or purple. Forms 

 assignable to this species occur also in the southern 

 states of Brazil. The species is probably a composite 

 one as now recognized. B.R. 21:1766 (as V. multifida, 

 var. contracta). Variable but unique species character- 

 ized by distinct, finely cut foliage and rosy lilac to deep 

 purple fls., but the clusters and individual fls. are too 

 small to make it popular. 



2655. Verbena Aubletia (X 



8. bipinnatifida, Nutt. ( V.pulcMlla of some German 

 seedsmen. V. montdna, Hort., in part). Perennial, 

 prostrate and rooting at base; stems stout, upright, 

 branched, 6-18 in. high: Ivs. rather thick, petioled, 

 1-2% in. long, scabrous above, ovate in outline, bipin- 

 nately parted or 3-parted into numerous oblong, rather 

 acute lobes 1-3 lines broad : spikes solitary, dense to 

 rather lax, at first capitate, becoming 2-4 in. long in fr. : 

 corolla 5-8 lines long, purple or lilac, limb 4-5 lines 

 broad, lobes emarginate to obcordate; throat of corolla 

 provided with a palisade of short hairs; upper stamens 

 bearing each a small oval to oblong purplish gland. 

 Texas to Neb. and Col. Flowers become bluish purple 

 in drying.
