RITIZIA (named in honour of Don Hippolite Ruiz, 

 author, in conjunction with Pavon, of " Florte Peruvian;^ 

 et Chilensis *'). Ord. StercuUace<T. A genus consisting 

 of only three species of stove shrubs, natives of Bourbon. 

 Calyx five-parted ; petals five, unequilateral, flat, per- 

 sistent ; staminal cup bearing twenty to thirty fertile 

 stamens ; peduncles axillary, cymosely many - flowered. 

 Leaves palmi-nerved, entire, lobed, or nearly dissected, 

 tomentose beneath. Two of the species have been intro- 

 duced, and are worth growing. They thrive in a com- 

 post of loam, peat, and sand. Propagated by cuttings, 

 which will root freely, if inserted in similar soil, under 

 a hand glass, in heat.

 Ord. Slerculiaceir. A genus comprising fifteen species

 or lobed. The species have no great beauty, the flowers 

 not exceeding \in. in diameter. Those described below 

 are from Australia, and thrive in a compost of loam, 

 peat, and sand. Ripened cuttings will root in either sand 

 or soil, if covered with a bell glass.

 late. April. I. very shortly petiolate, ovate or ovate-lanceolate,

 Ord. Polijgoaacea2. A large genus of perennial or rarely 

 annual herbs, sometimes sub-shrubs, rarely tall shrubs, 

 distributed thoughout all temperate climates. About 

 130 species have been enumerated, but the number 

 is estimated by some authors at less than lOU. Flowers 

 fasciculate in the nodes; fascicles axillary or disposed 

 in terminal racemes or panicles. Leaves sometimes all 

 radical, sometimes alternate on the stems and branches. 

 The species are mostly worthless, and, in some cases, 

 very troublesome, weeds. Eleven are natives of Britain, 

 among them may be mentioned R. Acetosa (Sorrel), the 

 leaves of which have been used as Spinach, and R. 

 Patient ia (Herb Patience).
