1. ALTH.&3A, L. Marsh-Mallow. 



Calyx surrounded by a 6 - 9-cleft involucel. Otherwise as in Malva. (Name 

 from ciXdco, to cure, in allusion to its healing properties.)

2. MALVA, L. Mallow. 



Calyx with a 3-leaved involucel at the base, like an outer calyx. Petals ob- 

 cordate. Styles numerous, stigmatic down the inner side. Fruit depressed, 

 separating at maturity into as many 1-seeded and indehiscent round kidney- 

 shaped blunt carpels as there are styles. Radicle pointing downwards. (An 

 old Latin name, from /xa\a^?j, soft, alluding to the emollient leaves.) 



1. M. rotundifolia, L. (Common Mallow.) Stems procumbent from a 

 deep biennial root ; leaves round-heart-shaped, on very long petioles, crenate, 

 obseurely-lobed ; petals twice the length of the calyx, whitish; carpels pubescent, 

 even. — Waysides and cultivated grounds : common. (Nat. from Eu.) 



2. M. sylvestris, L. (High M.) Biennial; stem erect, branched (2° -3° 

 high) ; leaves sharply 5-7-lobed; petals thrice the length of the calyx, large, 

 purple and rose-color; carpels wrinkled-veiny. — Waysides. (Adv. from Eu.) 



3. M. cnfsPA. (Curled M.) A tall, erect annual, with round and angled 

 toothed and crisped leaves, and small sessile flowers crowded in the axils, — spar-

4. M. moschata, L. (Musk M.) A low perennial; with the stem-leaves 5- 

 parted, and the divisions once or twice parted or cleft into linear lobes, faintly
