NATURAL HISTORY OF PLANTS.

inserted at a variable height in the tube of the corolla and alternate 

 with the lobes. In each cell is a descending anatropous ovule, with 

 the micropyle directed outwards and inwards, and the fruit has a thick 



putamen, hollowed in 

 Gaettarcia speciosa. ^ells oach Containing one 



descending seed. The 

 embryo is fleshy, sur- 

 rounded by an albumen 

 of little thickness, often 

 reduced to a simple 

 membrane. There are 

 Guettardas with only five, 

 four or three lobes to the 

 corolla, as many stamens 

 and as many ovarian 

 cells or less, two, for 

 example, with as many 

 stigmatiferous divisions 

 at the top of the style. 

 The calyx is caducous, 

 or persistent, as in An- 

 tirrhcea, Rohea, &:c. In other species the number of cells may become 

 very considerable, and then the cavities of the putamen may be 



disposed either without apparent order, or 

 in rayed series, double or simple, with 

 great regularity. This is the case especially 

 in Timonms^ species from tropical Asia and 

 Oceania and Madagascar, in which the 

 divisions of the corolla very shghtly over- 

 lap or are completely valvate, and in the 

 American Guettardas named Chomelia and 

 Malanea. This genus comprises, there- 

 fore, a great number of plants from the 

 tropical regions of the two worlds. The 

 leaves are opposite or verticillate, and the 

 flowers are in compound, often racemiform 

 and very frequently also uniparous cymes (fig. 289). They may be 

 solitary, and this is not unfrequently the case in the female specimens 

 of species whose male inflorescences are many-flowered. Hodgkinsonia
