LABIATE. 321 



LABIAT/E. 



Herbs with opposite leaves and cymes of flowers 



usually in very dense whorls at the leaf-axils or condensed 



into dense spikes of such whorls, and like BORAGE.E 



with fruit consisting always of four separate one-seeded 



nutlets. Corolla monopetalous, subequally five-lobed or 



strongly two-lipped. Stamens four, in two pairs, attached 



to the corolla-tube differing in position and relative 



length. Ovary superior seated on a conspicuous disc, 



of two carpels, but four-celled. Nutlets varying in the 



position of their attachment to the central axis. 



Species 2,000 or more, native mostly of the north temperate 

 regions, especially round the Mediterranean and in Asia Minor 

 and Syria. 



This large family is divided into a number of tribes of which the follow- 

 ing occur here wild or are common in gardens : — 



1. OCIMOIDE^ : perfect stamens four bent down ; anther cells 

 confluent (apparently one only to each anther). Basal scar of nutlet small, 

 e.g., LAVENDULA Lavender, coleus. 



2. SA TUREINE^ : perfect stamens four, the upper (middle) 

 pair longer, or two only straight and diverging. Corolla two-lipped or not, 

 e.g., MENTHA Mint, thymus Thyme, calamintha Catmint, 



3. MONARDE^ : perfect stamens two, anther cells of a stamen 

 separated by a short or long filament, and often one sterile or absent, e.g., 



SALVIA. 



4. S7 ACHYDE/E. : perfect stamens four, lower (outer) pair longest. 

 Upper lip of corolla hooded, lower lip spreading, three-fid, e.g., 

 SCUTELLARIA Skullcap, BRUNELLA Self-Heal, stachys Botony, etc. 

 LAMIUM Dead-Nettie, LEUt:AS. 



5. AJUGOIDEM : nutlets with a particularly large oblique or lateral 

 areola by which attached to the cen.ral axis, e.g., teucrium Wood 

 Germander, ajuga Bugle. 



PLECTRANTHUS. f.b.i. 112 viii. 



Cockspur Flower. 

 Herbs or undershrubs with flowers in loose cymes not 

 dense whorls, otherwise having the characteristics of the 

 family and tribe I OCIMOIDEM (p. 321), and remarkable 

 for the small calyx and much larger corolla, with upper 

 lip of three or four teeth, and lower very concave and 

 boat-shaped, in which lie the stamens,
