35. PARONYCHIACE^E. 
pulp with a fine raspberry -like flavour : that of P. Loved Heer 
(which as a sp. seems too nearly related to P. serratistipula 
DC.), called also Maracuja, being larger (about 4 in. long) 
and elliptic-oval, having a thinner softer or more yielding rind 
of a y. or when fully ripe bright orange-y. or red-lead coL, 
with mostly a strong pruinose or glaucous bloom, and with a 
pale bluisli-gr. and very juicy pulp like a gooseberry, is much 
the best fr. of the three. Its seeds were first sent to me from 
Tenerife by the Hon. C. E. C. Norton and Miss Young in 
1836-7 ; but it seems now to be altogether lost there. P. edulis 
Sims was introduced from England by the late Mrs. Penfold 
and myself in 1828 or 1830.
