 chemist; author of Viridarium Lusitanicum, Lisbon, 1661, 

 8vo. republished by Seguier in 1749. It is also in Ray's Syl- 

 loge stirpium exterarum). Lcefl. itin. p. 245. Lin. gen. no.

 and the 4 or 6 outer ones, or those produced from the sinuses, 

 horn-formed and smaller. Petals 4-6, oblong, unguiculate, in-

 puberulous on both surfaces, but paler beneath ; flowers usually 

 with 4 petals and 8 stamens. fj . S. Native of South America, 

 between Cumana and the Orinoco, and near Caraccas. Perhaps 

 the plant of Loofling, who says the leaves are glabrous, the 

 calyxes 4-toothed, and the flowers secund, is the same as that 

 of Humboldt, who says that the leaves are puberulous, the 

 flowers axillary, and calyx 8-toothed. Perhaps both plants 

 have 5 petals and 10 stamens in the flowers. Calyx greenish. 

 Petals hardly conspicuous, flesh-coloured. Stamens long, purple, 

 <5'ecttflrf-flowered Grislea. Clt. 1820. Shrub 4 to 6 feet.

 but smoothish above ; flowers 

 usually with 6 petals and 12 sta- 

 mens. T? . S. Native of the 

 north of Coromandel, on hills 

 (Roxb.), China (Lin.), and the 

 islands of Timor and Java. Ker.

 Tj . S. Native of the East Indies. Flowers red. Alabastra 

 turbinate. 



Dotted Grislea. Shrub.

 propagation is the same as that for Lansonia, p. 722.

 in important characters). D. C. mem. soc. hist. nat. gen. 3. pt. 



2. p. 70. Lobes of calyx exactly valvate in aestivation. Petals 

 numerous, alternating with the calycine lobes, and inserted at 

 the top of the calycine tube between its lobes. Stamens inserted 

 lower down in the calycine tube than the petals, and twice or 

 thrice their number. Seeds expanded into membranous wings. 

 Trees or shrubs. 



XXV. LAGERSTRCE'MIA (so named by Linnaus from 

 Magnus Lagerstrcem of Gottenburg, who procured many curiosi- 

 ties from China, and gave them to the public). Willd. spec. 2.

 tire. Peduncles axillary, usually constituting panicles or 

 racemes at the tops of the branches. Flowers purple, red or 

 white, showy.
