RUIZIA (named in honour of Don Hippolite Ruiz, 
author, in conjunction with Pavon, of * Flore Peruvianæ 
et Chilensis”). ORD. Sterculiacee. A genus consisting

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. Sterculiacew. A genus comprising fifteen species 
of greenhouse, stellate-tomentose shrubs or under-shrubs ; 
one is a native of Madagascar, and the rest are Aus- 
tralian. Flowers usually white, small, cymose; calyx five- 
fid; petals five, broadly concave at base, ligulate above ; 
stamens shortly connate at base; cymes axillary or oppo- 
site the leaves, rarely terminal. Leaves entire, toothed, 
or lobed. The species have no great beauty, the flowers 
not exceeding jin. 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. i

or pubescent beneath. h. 2ft. 1824. (B. M. 182.) : 
R. hermannicefolia (Hermannia-leaved), fl. in shortly pedun- 
culate cymes, April. Z usually narrow-oblong, jin. long, in 
luxuriant specimens often ovate-lanceolate, or with short, broad 
basal lobes, always obtuse, crenate, much wrinkled, white- 
tomentose beneath. h. 2ft. or more. 1818. (L. B. C. 1564, under 
name of Lasiopetalum d )

three to five-lobed. h. 2ft. 1819. (B. M. 2191; A. B. R. 603, 
under name of Commersonia dasyphylla.) ® 
parviflora (small-flowered). fl. small ; cymes shortly peduncu- 
late. April. Z. very shortly petiolate, ovate or ovate-lanceolate, 
obtuse, rarely lin. long, deeply crenate, and mostly lobed, with 
undulated, often crisped margins, glabrous or nearly so above, 
hirsute beneath. Branches prostrate or ascending, 6in. to 18in,

: ORD. Polygonacew. 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 sdme authors at less than 100. 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. 
Patientia (Herb Patience). 
RUMINATED. Pierced by irregular passages, as 
if chewed; e.g., the albumen of a nutmeg. 
RUNCINATE. Saw-toothed, or sharply incised, the 
teeth or incisions retrorse. 
RUNNER. A prostrate, filiform branch or stem, 
rooting at its extremity or elsewhere; e.g., the Straw- 
berry.

RUPPIA (named after H. B. Ruppius, a botanical 
author). ORD. Naiadacee. A genus consisting of one 
or more species of hardy, tufted, aquatic herbs, inhabiting 
the shores of temperate and tropical regions. R. maritima 
and its sub-species rostellata are natives of Britain ; the 
have no horticultural value. `
