progressed in their growth, and yet these differences so uniform, 

 that I felt satisfied that some special purpose was to be effected by 

 them. Taking therefore the larger species, L. Jlavescens, I have 

 examined very carefully, and without removing them from the 

 plants, a great number of flowers ; taking notes in almost every in- 

 stance for comparison with each other. I have also examined a great 

 many flowers at home microscopically ; perhaps therefore I cannot 

 do better than to read two or three of these notes. I have selected 

 those that will best shew the progressive stages through which the 

 organs of fertilisation of the plant pass. As in these notes I make 

 use of the word, cup, I may explain, that in this genus, the calyx- 

 tube is adnate with the ovary, but rising somewhat above it, while 

 the top of the ovary is itself a little depressed, a hollow cone or 

 cup is formed ; round the edges of which, but on the margin of 

 the disk, the stamens are arranged, with the style rising from the 

 depression in its centre. I may also say, that the whole of my 

 notes could be arranged in groups similar to that I now read. 



Note No. 1. — Stamens all perfect and bent over the stigma, 

 Anthers not yet open. Stigma scarcely formed; being a mere speck 

 sessile upon the ovary. 



No. 2. — Stamens perfect. Anthers fully developed and 

 apparently ready to open ; all bent over the stigma. Style scarcely 

 a quarter of a line high. Stigma very small, not the tenth of a 

 line wide. 



No. 3. — Stamens perfect ; bent over the stigma. Anthers seem 

 almost bursting. Style half a line high. . Stigma wider than in 

 number two, but far from maturity. 



No. 4. — Stamens all perfect, but much more erect than in 

 number three. Anthers open, but retaining their pollen. Style 

 a line high. Stigma still small ; but becoming somewhat peltate. 



No. - r >, Stamens perfect ; all erect but five, which are still bent 

 over the stigma. The anthers of the erect stamens open ; those of 

 the bent ones still closed. Style one and a-half lines high. 

 Stigma broad and peltate, but not mature. Some loose pollen in 

 the cup, round the base of the style.
