GENERA FUMARIA AND RUPICAPNOS, 329 
characters, but in shade-grown plants of some species it does not always 
attain its normal development. So far as can be judged from the limited 
material examined, the corolla is more uniform in the species of this genus 
than in Fumaria, and shows little tendency to cleistogamy. 
CONSPECTUS OF SPECIES. 
Secrion I. MURICARIA. 
Suberect annual plants with cauline leaves and few-flowered racemes. Flowers small or 
rather so, 4-8 mm. long, white; outer petals rarely dilated apically into a spreading, sub- 
orbicular limb, little longer than the inner petals, which are tipped with dark purple. Fruit 
very large, or at least of moderate size. | 
* Leaves 2-trisect.  Racemes subsessile. 
l. R. muricaria. Flowers 7-8 mm. long ; lower petal spathulate. Fruit very large, sub- 
rotund, marginally muricate, with long, large beak, 
** Leaves 2-pinnatisect, Racemes peduncled. 
2. R. delicatula, Leaves with multifid leaflets. Flowers 4 mm. long; outer petals 
apically dilated. Fruit subglobose, muricate, apiculate. 
8. R. longipes. Leaves deltoid. Flowers 6-8 mm. long; lower petal dilated into a 
suborbicular limb. Fruit very large, subrhomboid, muricate, with 
large, broad beak. Pedicels very long. 
4. R. pretermissa. Leaves deltoid. Flowers 6-7 mm. long; lower petal spathulate. 
Fruit rather large, ovate-elliptical, finely rugose, with compressed 
beak. 
5. R. sublevis. Leaves oval, with closer leaflets, Flowers... Fruit of moderate 
size, narrowly obovate, finely rugose, with small beak. 
SrcrtIon II. SARCOCAPNOIDES. 
Decumbent perennial plants with quinate-pinnate, mostly subradical leaves and many- 
flowered racemes. Flowers small or rather so, 4-10 mm, long; outer petals each apically 
dilated into a spreading, suborbicular limb, distinctly longer and broader than the inner 
petals, which are tipped with dark purple. Fruit small. 
6. R. sarcocapnoides. Lobes of leaflets elliptical, Flowers 4-5 mm. long, white; lower 
petal not saccate. i 
7. R. Heboudiana. Lobes of leaflets cuneiform. Flowers 9-10 mm. long, rosy-white 
lower petal saccate. 
Secrion III. TRIPTERYX. 
Decumbent perennial plants with 2-3-pinnatisect, mostly subradical leaves and many- 
flowered racemes. Flowers small or rather so, 4-10 mm. long, whitish and more or less 
tinted with yellow; outer petals more or less apically dilated into spreading, suborbicular 
limbs, little longer than the inner petals, which are conspicuously winged and at most 
obscurely tipped with dark purple. Fruit small to rather large. 
* Flowers 4-5 mm. long; lower petal not saccate. 
! Lower petal gradually dilated apically. 
8. R. numidica. Leaves subdeltoid with remote leaflets, Spur of upper petal very 
small, straight. Fruit oblong-obovate.
