Cattleya Portia, or Porcia? For a while I thought they were the same thing — just two different spellings. The mystery is solved:
Cattleya bowringiana’s contributions to hybridization, however, go well beyond the coerulea. Its two most famous contributions are Cattleya Portia, its hybrid with the autumn-flowering, large-flowered species Cattleya labiata, and Cattleya Porcia, its cross with Cattleya Armstrongiae (Hardyana x loddigesii). Both C. Portia and C. Porcia are intermediate in size between their parents. They are beautifully colored, vigorous growers with tall heads of flowers and they make an impressive display. They are considered by many Cattleya experts to be among the finest and most spectacular Cattleya hybrids ever bred.
Cattleya Portia was registered by James Veitch & Son in 1897 and C. Porcia by H.G. Alexander in 1927. Both have received many awards from the RHS and AOS. Cattleya Porcia ‘Cannizaro,’ which received AMs from the RHS in 1936 and the AOS in 1951, actually received an FCC/AOS as late as 1988 in recognition of its excellence.
