Names Of Plants: Sense and Sound - Part Five
Theo Smid
Hayward, California
This series, "Names of Plants: Sense and Sound", continues with Part Five, a listing of rhododendron and other ericaceous genera beginning with G, H, I, J and K. The first installment was in the ARS Journal , Vol.42:1, Winter 1988. It will continue in future issues.
Mispronunciation of plant names is not uncommon. Generally mispronounced are words that end in the Greek -ides "likeness or resemblance," common in botany, biochemistry and medicine, e.g. hippophaeoides , in which o creates the combining form of the basic word: -o-eye-des or -o-i-des. This construction is not to be confused with the dipthong in a word like android or adenoid .
Some species are named for persons of various nationalities. The sound of ch , in particular, varies. It is gutteral ch in German, e.g. R. bachii ; sh in French, e.g. R. chevalieri ; k in Italian, e.g. R. scortechinii . Rhododendron stresemannii , German, begins with shtr . The hs in R. chihsianum is pronounced approximately as sh .

In 1924-25 he was commissioned by Prof. Charles S. Sargent, creator of Arnold Arboretum, and the Harvard Mus. of Comparative Zool. to explore two little-known ranges on the Chinese-Tibetan border. In 1928-29 he collected in Yunnan for garden owners in Britain and the U.S. and explored for the National Geographic Society. In 1926 he sent to the Arnold Arbor, seeds of the magnificent
Paeonia suffrutticosa
'Rock's Variety,' which had been cultivated at the lamasery of Choni. In 1938 the lamasery was burned to the ground during a Moslem uprising. The lamas were killed and the peonies destroyed. After the lamasery was rebuilt Rock obtained seeds from the arboretum. The Rock Rhododendrons are listed in

Flora Fennica
.) Before starting out from Philadelphia, he was "seized with terror at the thought of ranging so many new and unknown parts of natural history," even though John Bartram had given him much advice and encouragement. From the Delaware Water Gap he traveled to Quebec and Montreal. The governor of Canada had received orders from France to assist Kalm in every way possible; Dr. Gaulthier made botanical excursions with him. Later he explored the country of the Iroquois. During his stay in America he sent seeds to England and saw the resulting plants when he stopped off there on his return. He brought back to Sweden a herbarium of c. 325 spp., many of which Linnaeus later described in the
Species Plantarum
, and a wife, a pastor's widow. In commemorating
Kalmia

Rhododendron leachianum
, but Rehder reclassified it as
Kalmiopsis leachiana
. It was introduced in 1933. In 1960 Marcel le Piniec found a second form about 100 miles away. The Leach form is named for the Rogue River and the other for the Umpqua River. 'M. le Piniec' is a clone of the latter.
