Nat. Ord. TropmoLex2®.—Ocranpria Monoeynia. 
Gen. Char. (Vide supra, ‘Tas. 4097.) 
TropxoLum crenatiflorum ; glaberrimum, scandens, foliis peltatis semiorbiculatis 
5-lobis, lobis obtusis v. retusis cum mucronulo, petalis calyeem attenuato- 
calcaratum subsuperantibus, obovatis patentibus subsequalibus apicibus 
truncatis subbicrenatis, 2 superioribus sanguineo-lineatis. 
This is another new Peruvian Jndian-Cress introduced by 
Mr. Veitch, through his collector, Mr. W. Lobb, from Pillao and 
Chagula, Peru; and may be treated like the other well-known 
species of the same genus, that is as hardy during the summer 
months. Its nearest affinity is perhaps with 7: Loddianum (Bot. 
Mag. t. 4097), but the foliage, the colour of the flowers, the 
edge of the petals, and the relative length of those petals, as 
compared with the spur, at once distinguish it. | 
Descr. A long, straggling and climbing plant, glabrous in 
every part. eaves alternate, petioled, generally small, semi- 
orbicular or nearly orbicular, with a broad truncate base, peltate, 
but the point of attachment of the pediole is nearer the base than 
the middle ; five-lobed, the lobes rounded, very obtuse, or more 
generally retuse, with a very small soft mucro. Peduncles axil- 
lary, slender, single-flowered, flexuose or even cirrhose, longer 
than the petioles. Calyz deeply cleft into five, appressed, lan- 
ceolate, rather obtuse segments, at the base above extended into 
a rather alternated spur, suddenly ending in a narrow curved 
point or mucro, scarcely twice the length of the calyx : segments 
and spur yellow, tipped with green. Petals about twice as long 
as the segments of the calyx, obovate, retuse, nearly equal, the 
apex truncate or retuse with generally two notches and three 
obtuse teeth: all yellow, the two upper petals only with a few 
black purple streaks. Stamens eight, unequal, much shorter 
than the petals. Style shorter than the stamens.
