Natural Order CRASSULACE. 
Genus Crassuna, Linn. 
C. quapriripa (Baker). Glabra robusta perennis carnosa pedalis- 
sesquipedalis, foliis oppositis decussatis horizontalibus cras- 
sissimis utrinque viridibus conspicue punctatis plerisque petio- 
latis oblongo-spathulatis supremis rotundatis subsessilibus, 
floribus quadrifidis thyrsoideo-paniculatis, petalis lanceolatis 
albis rubello tinctis flore expanso stellatis, calyce 5—6-plo 
longioribus, carpellis et filamentis albis petalis paulo bre- 
vioribus. 
A native of the Cape of Good Hope. 
Glabrous, perennial, a foot and a half to two feet high, very 
fleshy. Leaves opposite, decussate, horizontal, the lower ones 
oblong-spathulate, two to three inches long, entire, often emar- 
ginate at the point, narrowed suddenly into a flattened petiole, 
the upper surface apple-green, not at all glaucous, scattered over 
with numerous conspicuous pitted pustular dots, the lower 
surface paler; the uppermost leaves roundish, subsessile, placed 
some distance from the panicle. lowers 100 or more in a 
moderately close thyrsoid panicle with erecto-patent branches. 
Pedicels one to three lines long, with a pair of minute lanceolate 
bracts at the base. Calyx very minute, with four deltoid lobes. 
Corolla tetramerous, star-like when expanded, four and a half to 
five lines across; the petals lanceolate, white, tinged with red on 
the outside. Stamens and carpels four each, equal, rather shorter 
than the petals. 
This is a plant quite exceptional in the genus Crassula by its 
constantly tetramerous flowers. Of the quinquefid species, it has 
the leaves and general habit of C. cordata, Aiton, Hort. Kew, in. 
196, but differs in the inflorescence.

This pretty new Crassula, much resembling an allied species, 
cordata, I obtained from my friend the Rev. H. N. Ellacombe, of 
Bitton, so well known for his fine collection of hardy herbaceous 
and other plants. The plant is of easy culture, flowers freely, 
and continues for a long time in blossom, making it very useful 
for conservatory or greenhouse decoration.—W. W.S.
