Orper LXXXVIII. ASCLEPIADEZ. 
(By N. E. Brown.) 
Flowers regular, hermaphrodite. Calyx of 5 free sepals or rarely 
5-lobed, persistent; segments imbricate, usually with minute pro- 
cesses at their base within. Corolla hypogynous, gamopetalous, 
5-lobed, vary variable in shape and size, the lobes imbricate, con- 
torted or valvate in eestivation, often recurved or reflexed, sometimes 
with the sides folded backwards (replicate), in a few genera connate 
at the tips, rarely connate into a column at the middle then free and 
again connate at the tips, the sinuses between them sometimes 
produced into teeth, with 1-3 series of free or connate lobes, processes, . 
keels, tubercles or flaps arising from the corolla or the staminal 
whorl, forming the corona, sometimes absent. Stamens 5, inserted 
at or near the base, rarely at the middle or mouth of the corolla- 
tube, alternating with the corolla-lobes ; filaments sometimes free, but 
usually connate at their base or throughout into a staminal column, 
the apex often united to the dilated part of the style; anthers not 
connate or only by their appendages, free or united to the dilated 
part of style, 2-celled, opening by apical, longitudinal or transverse 
slits; margins of the cells or their basal prolongations more or less 
horny and wing-like (anther-wings), usually projecting outwards ; 
adjacent wings of each pair of anthers nearly meeting, leaving very 
narrow fissures leading to the stigmatic cavities; connectives often 
produced into membranous or rarely fleshy or inflated terminal 
appendages or apiculate or unappendaged ; appendages free or connate. 
Pollen granular or united into 1 or 2 waxy masses, attached in pairs 
or in fours, sometimes direetly, but more usually by means of arm-like 
processes (caudicles) to each of the 5 small or minute, horny or rarely 
soft bodies (pollen-carriers) at each angle of the dilated part of the 
style; when granular, each granule consists of 4 pollen-grains or of 
3-5 grains in a row, and then held in horny pollen-carriers with a 
spoon-, trumpet- or trowel-shaped entire or bifid blade, tapering 
downwards into a short or long stalk attached to a soft adhesive 
gland. Pistil superior, formed of 2 one-celled carpels, free below, 
but their styles united above and dilated at the middle or apex into 
a pentagonal disk ; style-apex flat or depressed in the centre, with or 
without a central simple or bilobed apiculus, or convex, pyramidal 
or prolonged into a long beak of variable form, which is entire, 
bifid or dilated, rarely there arises from the disk 2, 5 or 7 style-like
