 Lime-trees of Europe.

l.GREWIA, Linn. ; Fl. Brit. Ind. i. 383. 



Trees or shrubs, more or less stellate-pubescent. Inflorescence 

 usually axillary. Sepals 5, distinct. Petals 6, rarely 0, smaller than 

 the sepals, with usually a glandular scale within at the base. 

 Stamens and ovart/ usually on a raised torus or gynophore. 

 Stamens many, distinct. Stamhiodes 0. Ovary 2-4-celIed, with 2 

 or more ovules in each cell ; style subulate ; stigma shortly lobed. 

 Drujpe fleshy or crustaceous, entire or 2-4-lobed, containing 4 bony- 

 stones, which are often divided into 2 or more false cells and 1-6- 

 seeded. /S'eeoJ^ ascending ; albumen fleshy, rarely 0. — Species about 

 90, confined chiefly to Tropical Asia and Africa, a few also occurring 

 in the islands of the Malay Archipelago and ia N. Australia. 



There is usually at the base of each petal a conspicuous! gland,' and this 

 is correlated with a distinct gynophore. In some species,lhowever,*the 

 petals have no thickened gland at the base, and there is no gynophore. 

 As both forms of petals sometimes occur in the same species , the diifer- 

 ence in character must be interpreted as representing a kind of sexual 

 dimorphism. Petals with no thickened basal glands have been found 

 by the writer in the following species : — 6r. orbiculata, Q. tilimfolia, 

 G. vestiia and G. elastica, and in the last-mentioned species the gland- 

 less condition almost invariably occurs. In G. asiatica, which is abund- 

 ant within 'the area, the petals are always provided with a conspicuous 

 gland and an obvious gynophore. Sir Dietrich Brandis, who first drew 

 the writer's attention to the occasional absence of these basal glands, 

 has informed him that he has found them wanting also in G. elatostem- 

 woides, Coll. and Hemsl., in G^.eriocarpa, Juss., and in a few other 

 extra-Indian species. 



The following key has been prepared mainly with a view to the pre- 

 sentation of characters which are more obvious than such as should be 

 used in a strictly natural classification. Of the 18 species occurring 

 within the area of the Upper Gangetic Plain, eight are endemic in India.
