LABIATE 375 



The ovary is usually stipitate in Scutellaria as is the shortly 

 lobed ovary in the tribes Prostanthereae and AjugoideaB. 



The nutlet is depresso-globose in Salazaria and Scutellaria, 

 fleshy in Gomphostemma and subdrupaceous in other members 

 of the tribe Prasieae. The radicle is long and incurved in 

 Catopheria, with accumbent cotyledons. The seed is trans- 

 verse to the axis in Salazaria and Scutellaria with an incurved 

 radicle and incumbent cotyledons. 



About five more or less distinct types of seeds have come 

 under my notice differing chiefly in shape, dependent upon 

 that of the nutlet containing them. One of the simplest 

 forms is that represented by Salvia Sclarea (fig. 589) which 

 has small obovoid seeds with a straight embryo conforming 

 to the interior. The cotyledons are oval, plano-convex, and 

 slightly auricled at the base to accommodate the radicle. 

 There is a thin film of endosperm in the seed, but so small as 

 to be practically of no importance. The seed of Thymus 

 Mastichina differs in being very much smaller and globose 

 with suborbicular cotyledons. 



A second type is that shown by Salvia argentea. The 

 nutlet and seed are broadly oblong-oval. The cotyledons 

 are similar in outline, plano-convex and rather deeply auricled 

 at the base. The transverse section of the nutlet, seed and 

 .embryo is elliptic, or slightly trigonous. Teucrium multi- 

 florum conforms pretty closely to this type, but the nutlets 

 are muricate or covered with little tubercles. 



Salvia verbenacoides has a smooth nutlet, broadly oval in 

 transverse section, but otherwise conforming to S. argentea. 



The nutlet of Ocimum Basilicum is oblong-ovate with 

 rather a notable constriction about the middle. The coty- 

 ledons conform to this outline and are shortly auricled at 

 the base. In transverse section the nutlets are broadly 

 oval. 



The nutlets of Nepeta nuda (fig. 593) are notably trigonous 

 in transverse section, broadly oblong-oval in outline, and 

 scabrid or muricate all over the surface. The cotyledons in 

 conforming to this characteristic shape are of different forms 

 or differently disposed while yet in the seed. That on the 

 ventral aspect is convexo-concave, with a blunt angle next
