teeth, the alterant: ones shorter; corolla small, white. Escaped from gardeni 

 into waste places. (Nat. from Eu.) 



28. O ALI-: 01' SIS, L. HEMP-NETTLE. 



Calyx tubular-bell-shaped, about 5-nerved, with 5 somewhat equal and spiny- 

 tipped teeth. Corolla dilated at the throat; the upper lip ovate, arched, entire; 

 the lower 3-cleft, spreading ; the lateral lobes ovate, the middle one inversely 

 heart-shaped ; palate with 2 teeth at the sinuses. Stamens 4, ascending- under 

 the upper lip : a////W-r t //.s tfmiMu'scly 2-valved; the inner valve of < ach cell bristly- 

 fringed, the outer one larger and naked. Annuals, with spreading branches, 

 and Several - many-flowered whorls in the axils of floral leaves which are nearly 

 like the lower ones. (Name composed of yaXer/, a uxasel. and o-^is, resem- 

 blance, from some likeness of the corolla to the head of a weasel.) 



1. Cr. TETRAHIT, L. (COMMON HEMP-NETTLE.) Stem swollen Mom t/>e 

 joints, bristly-hairy ; leaves ovate, coarsely serrate ; corolla purplish, or variegated, 

 about twice the- length of the calyx; or, in var. GRANDIFLORA, 3-4 times the 

 length of the calyx, often yellowish with a purple spot on the lower lip. 

 Waste places, rather common. Aug. (Nat. from Eu.) 



2. O. LADANUM, L. (RED HEMP-NETTLE.) Stein smooth or pubescent;

 united to form an upper lip. Corolla not dilated at the throat; the upper lip 

 erect or rather spreading, often arched, entire or nearly so ; the lower usually 

 longer and spreading, 3-lobed, with the middle lobe largest and nearly entire. 

 Stamens 4, ascending under the upper lip (often reflexed on the throat after 

 flowering): anthers approximate in pairs. Nutlets obtuse, not truncate. 

 Whorls 2 -many-flowered, approximate in a terminal raceme or spike (whence 

 the name, from erra^us, a spikt}. 



* Root annual : gtenw- decumbent, low.
