9. MODIOLA, Moeuch. (The fruit of the form of a modiolus, which is 

 either a small measure or the nave of a wheel.) _ — Low and diffuse chiefly sub- 

 perennial herbs, of the warmer parts of America, hirsute with simple or geminate 

 hairs ; with rounded palmately lobed and incised green leaves, small flowers soli- 

 tary on axillary peduncles, a persistent involucel of 3 foliaceous bractlets, small 

 dull-red petals, a depressed fruit of 15 to 30 thin-coriaceous carpels ; these reni- 

 form, much compressed, the back at summit bearing a bipartible cusp, at length 

 falling free from the axis, and tardily 2-valved from the top. — Meth. 619 ; St. 

 Hil. Fl. Bras. Merid. i. 210, t. 43 ; Gray, Gen. 111. ii. 71, t. 128. — Several forms, 

 probably all of one species. 



M. multiflda, Miench, l. c. 620. Stems a span to a foot or two long : peduncles commonly 

 filiform and equalling or surpassing the petiole : petals 2 or 3 lines long, little surpassing 

 the calyx : carpels hirsute, at least when young. —Torr. & Gray, Fl. i. 229. M. Caroliniana, 

 Don, Syst. i. 466; Gray, Gen. 111. ii. 72, t. 128. Malva Caroliniana, L. Spec. ii. 688 (Dill.

10. H0RSF6RDIA, Gray. (Frederick Hinsdale Horsford, of Vermont, 



associate of C. G. Pringle in the collection of rare N. American plants.) — 



Densely and somewhat roughly stellular-tomentose shrubby or suffruticose plants, 



with much the habit of Ahutilon or Sphteralcea, with carpels rather of the latter 



but seed of the former ; the leaves cordate to lanceolate and barely denticulate, 



thickish ; the chiefly axillary peduncles 1-flowered. — Proc. Am. Acad. xxii. 296, 



— Two species.* 



H. alata., Gray, 1. c. 297. Frutescent, 3 to 6 feet high : leaves subcordate and ovate-lanceo- 

 late (1 to 3 inches long) : petals purple, half inch long, much surpassing the ovate-acuminate 

 calyx-lobes: carpels 10 or 12, with upper pair of ovules abortive ; upper empty portion de- 

 hiscent long before maturity into a pair of narrowly oblong obtuse erect scarious wings of 

 thrice the length of the basal seminiferous body. — Sida alata, "Wats. Proc. Am. Acad. xx. 

 356. — Along water-courses in mountains of N. "W. Sonora, below the boundary of Arizona, 

 Pringle. (Therefore Mex.) 



H. Newberryi, Gray, 1. c. More shrubby : lower leaves more cordate : petals bright 

 yellow (according to Orcutt's note), quarter inch long, nearly twice the length of the acutish 

 calyx-lobes : carpels 8 or 9, 2-3-seeded ; the scarious upper 2-valved portion obliquely and 

 broadly oval, somewhat divergent, hardly twice the length of the reticulated basal body. — 

 Ahutilon Newberryi, Wats. Proc. Am. Acad. xi. 125 ; Brew. & Wats. Bot. Calif, i. 87, excl.

11. ANODA, Cav. (Ceylonese name of an Abutilon, recorded by Bur- 

 mann, taken up for this American genus by Cavanilles.) — Annuals, chiefly 

 Mexican, with variable hastate or deltoid or cordate leaves (sometimes 3-5-cleft) 

 and single flowers on slender axillary or at summit racemose peduncles. — Diss.
