NOMENCLAtUIlE. 



3. ^stivatio induplicativa, when the parts of the corolla 

 are bent inwards, and touch each other with the folds of their 

 margins, as the margins of the valves in the capsules of Vio- 

 lets. We observe this estivation in some of the Clematidae. 



4. j^stivatio alternativa^ when the parts of the corolla 

 stand in two or more rows, in such a manner that the interior 

 row is cohered partially and alternately by the exterior. This 

 is observed in most of the Liliaceae. 



5. JEstivatio quincuncmlis^ when, of five parts, two are ex- 

 terior, and two interior, and the fifth covers the interior with 

 one of its sides, and is again partially covered by the exterior, 

 as we observe in the calyces of roses. 



6. ^stivatio vexillaris. This takes place in the papilion- 

 aceous flowers ; the standard covers the three other parts. 



7. ^stivdtio cocJdcaris, when one part is larger than the 

 others, and, bending itself into a spoon-shape, it incloses them, 

 ^his is the case in Aconitum, in some of the Personatae, and 

 in Antholyza. 



8. JEstivatio imbricativa, when the parts stand in several 

 rows, and the exterior and shorter parts cover only the base 

 of the interior, as we observe in the common calyces of the 

 compound flowers. 



9. ^stivatio convolutiva, when the exterior part is bent^ 

 and incloses the interior, this again the following, and so 

 "forth, as we observe particularly in the cruciform flowers. 



10. jEstivatio plicativa, when all the parts are folded into 

 'one another, without any particular order, as we observe in 

 the Poppy, and in the Needhamia of Br. 



And, lastly, we must observe, what seems to make an es- 

 sential difference between the corolla and the calyx, that their 

 "estivation is completely different ; for example, the astivatio 

 of the calyx of the Garden Pink belongs to No. 5., and that 

 of its corolla to No. ^.

We must yet further notice, with respect to the corolla, its 

 time of full blow (anthesis). We mean by this, the point of 

 time when the parts of the corolla, as being the organs of
