760 ASCLEPIADE& (Brown). | Hustegia. 
Small tuberous-rooted perennials, branching at ground-level into many decum- 
bent or ascending stems ; leaves small, opposite, linear-filiform to linear-hastate ; 
flowers small, in pedunculate umbels, lateral at the nodes. 
Distris. Species 5, endemic. 
The 3-seriate corona readily distinguishes this genus from all except Emicocarpus. 
The species are difficult to discriminate and require to be studied in the living state 
to determine their limits of variation. 
Middle series of corona-lobes divided into 3 distinct 
8 ents : 
Leaves 2-5 lin. long, linear-hastate, acute ; lateral seg- 
ments of the middle corona-lobes with an (often 
inflexed) auricle near the base : 
Middle corona-lobes divided 4-3 of the way down 
into segments 4-4 lin. long, distinctly shorter 
than the style i ... (1) fraterna. 
Middle corona-lobes divided almost to the base and 
rising as high as the top of the style... ... (2) minuta, 
Leaves or most of them 4-14 in. long, filiform or 
filiform-hastate, rarely linear-hastate : 
Corolla-lobes 13-12 lin. long; middle series of 
corona-lobes without distinct auricles to their 
lateral segments ... «1. se ves es» (3) ffiliformis. 
Corolla-lobes 33 lin. long ; middle series of corona- 
lobes with rounded auricles to their lateral 
segments ... ue : Ae eis ... (4) macropetala. 
Middle series of corona-lobes with inflexed triangular 
auricles at their base, but scarcely 3-lobed ; leaves 
filiform, rarely filiform-hastate os ... (5) plicata, 
1. E. fraterna (N. E. Br.) ; plant in habit, size and form of leaves, 
arrangement and size of flowers exactly as in E. minuta, differing as 
follows :—corona-lobes of the outer and middle series about } lin. 
long, shorter than the style; outer series entire, 4 lin. broad, 
linear-oblong, rounded at the apex, with a large gibbosity on the 
inner face near the top ; middle series divided }—} of the way down 
into 3 linear segments about 1-1 lin. broad, with the middle one 
much longer than the lateral and having a large gibbosity on its 
inner face at the base, and the base of the lateral segments or 
margin of the united part more or less dilated into inflexed auricles ; 
inner series entire, 4 lin. long, linear or linear-oblong, obtuse, 
scarcely exceeding the anther-appendages; style exserted } lin. 
beyond the anther-appendages, } lin. thick and oblong or sometimes 
nearly as thick as long, very obtuse. E. hastata, Spreng. Neue 
Entdeck. i. 268, t. 1, fig. 5-10, and Syst. Veg. i. 854, not of R. Br. 
Var. 8: pubescens (N. E. Br.); rather densely pubescent on the stems, 
leaves, peduncles and pedicels ; outer corona-lobes spathulate, suborbicular and 
twice as broad at the apex as at the base, otherwise as in the type.
