PITTOSPORE. 
Lanceolate-leaved Senacia. Shrub 10 feet. 
4 S. ELLIPTICA (Lam. ill. no. 2711.) leaves elliptical, obtuse ; 
flowers axillary, disposed in something like fascicles. h. S. 
Native of the Antilles. Like Rhdmnus sarcomphalus. A very 
doubtful species. Perhaps referable to Celdstrus or Mayténus. 
Flowers white. 
Elliptical-leaved Senacia. Shrub. 
Cult. All the species of Sendcia will grow well in a mixture 
of loam and peat, or any rich light soil; and ripened cuttings 
planted in a pot of sand under a hand-glass, placed in heat, 
will root freely.

Frankénia in many important particulars.) St. Hil. mem, plac. 
cent. p. 39. and mem. mus. 12. p. 77. D. C. prod. 1. p. 349. 
Calyx of 4-5 erect (f. 74. b.) or spreading (f. 77. a. f. 76. a.) 
sepals, united at the base into a furrowed tube (f. 74. a.), 
or cleft to the base (f. 76. a. f. 77. a.), permanent, equal, 
rarely unequal, lanceolate or linear acute. Petals hypogynous, 
equal in number to the sepals, and alternating with them, 
sometimes unguiculate (f. 74. b.). Claws length of calyx, 
with a spreading limb (f. 74. b.) in this case the throat is usually 
crowned with petal-like scales as in Carophyllee, sometimes 
sessile, spreading (f. 76. b.), sometimes with a 5-petalled (f. 76. 
d.) or 5-toothed urceolus (f. 77. d.) between the petals and the 
Stamens. Stamens hypogynous, sometimes equal in number 
with the petals (f. 74. d.), in this case they are alternate with 
them; or double that number, when this is the case the alternate 
ones are opposite the petals, but sometimes multiple that 
number; filaments filiform (f. 74. d.) or very short. Anthers 
roundish, linear or elliptical, bursting laterally by 2 pores at the 
apex, seldom at the base. Ovary 1 (f. 74. g. f. 77. e. f. 76. e.), 
free. Style filiform (f. 74. e.), simple (f. 77. d.). bifid or trifid 
(E 74. f). Capsule ovate-oblong (f. 77. e.), somewhat tri- 
gonal, 2-3-valved (f. 74. g. f. 75. d.), 1-celled or incom- 
pletely 3-celled from the valves being bent inwards at the 
edges; valves bearing seminiferous placentas at the margins 
on both sides (f. 74. g.), many-seeded. Seeds small. Em- 
bryo straight in the middle of the albumen, with a short 
radicle pointing towards the umbilicus, and flat leafy cotyle- 
dons. This order is composed of elegant little herbs, subshrubs 
or shrubs, with simple and branching stems, and opposite alter- 
nate whorled or crowded, entire, ciliated or toothed leaves, 
stipulate or exstipulate, when this last is the case the base is 
produced into stem-clasping membranes, usually furnished with 
glands; the stipulas when present are usually fringed. The 
flowers are either white, rose-coloured, or yellow, axillary or 
terminal, when they are axillary the peduncles are 1-flowered, 
when they are terminal they are either disposed in corymbs or 
loose racemes. Pedicels always propped by a leaf or bractea. 
This order differs from Violarite and Caryophillee as well 
as from all the neighbouring orders, in the seeds being fixed to 
the Margins of the valves, to marginal parietal nerves or dissepi- 
ments, not to intervalvular placentas, as in Violarié@, nor to cen- 
tral placentas as in Caryophillee. The medicinal virtues of the 
Plants contained in this order are very slight. The seeds of all 
are truly difficult to preserve in a living state for more than a
