Nature to advance from the raore diffuse vegetable life, to the more 

 collected, concentrated animal life, and thus to consciousness." 



" Examen Organographique des Nectaires, par M. L. Bravais. — 

 Linnaeus designated as nectaries those parts of the flower which se- 

 crete a sweet fluid ; but he not only included many parts in which no 

 such secretion can be perceived, but also described as nectaries 

 whatsoever was neither calyx, flower, stamen, pistil nor ovary. Sci- 

 ence is in want of an expression, says the author, to distinguish a 

 portion of the male apparatus (andraeceum) or even a circle of parts, 

 which may or may not secrete a nectareous fluid. Most of the ex- 

 pressions employed do not answer their purpose. In the absence of 

 better the author chooses the terras nectary and disc ; the first ac- 

 cording to the Linnaean definition, the second in the case where the 

 nectaries form a circle, or ring (Wirtel). Then follow the divisions 

 of the nectaries, according to situations where they occur. 



"1. Calyx-nectaries. To this division belong the glands of the 

 calyx in many Malpighiacese, some Euphorbiaceae, the spur on Im- 

 patiens Balsamina, also the nectary which occurs at the base and 

 within the sepals of the Malvaceae, as in many kinds of Malva, in La- 

 vatera trimestris, &c. It forms a whitish and rough swelling (bour- 

 relet). 



" 2. Hypopetalous nectaries. Only one example is known to the 

 author ; externally, and at the base of the flower of Chironia decus- 

 sata is found a yellow, notched ring, which produces honey. 



" 3. Corolla-nectaries. They occur in most flowers, especially in 

 the lower portions of the petals, in the form of pits, channels, spurs, 

 &c. 



" 4. Hypostaminal nectaries (Hypostemone Nektarien), between 

 the corolla and the stamens. The author observed them in sixteen 

 natural orders : Capparideae, Resedaceae, Hippocastaneae, Ampelideae, 

 Geraniaceae, Oxalidaceae, Sapindaceae, Terebinth aceae, Passifloreae, 

 where they constitute numerous filaments and cavities secreting ho- 

 ney ; Loaseae (in which I have called them ' Parastaminal '), Cucnrbi- 

 taceae, Asclepiadese, the corona of which they form (which I have 

 named Paracorolla) . 



" 5, Staminal nectaries. The author describes here many such : 

 e. gr. in a double columbine, in the violet, Fumaria, Corydalis, Dia- 

 nella, the Laurineae, Vinca, Phaseolus, Alsine media. 



" 6. Nectaries inserted between the stamens, as in Melianthus ma- 

 jor and minor, Tropaeolum, several Cruciferae, Sibbaldia procumbens.
