ON THE BOTANY OF THE LIZARD PENINSULA. 335 



perhaps, have been a more natviral northern boundary for our list than 

 the one we liave taken. North of tlie creek, the space between the eastera 

 and western shore of the promontory is not less than ten miles, and there 

 is in the centre a tract of undulated s;ranite-country that stretches from 

 Constantine and Helston beyond our bounds into the centre of the county, 

 and on the east of this, stretching down to the shore of Falmouth, ex- 

 tends a tract of still more decidedly sylvan and sheltered Devonian country 

 wliich furnishes a marked contrast with the Serpentine. Here are situated, 

 on the sloping banks of a small stream, opening out towards the south- 

 east to the mouth of Falmouth harbour, the garden and grounds of Pen- 

 gerrick, the residence of K. W. Fox, Esq., F.R.S., in which are cultivated 

 in the open air a large number of trees and shrubs of delicate constitution, 

 that cannot be grown without winter-shelter round Loudon. We saw 

 here a llhododendron, measuring ISO feet in circumference, and well- 

 established trees or bushes, grown without shelter, of Erica arborea, 

 Laiirun Camphora, various species of Eucalyptus, Mctrosuleros, and Mela- 

 leuca, several of the long-leaved Mexican Pines and Sikkim Rhododen- 

 drons, ChaiiKerops humUis, Beutltamia, Arhntas, and Pernttlya with ripe 

 fruit, a tree of Pruiins Laurocerasns, 40-.50 feet high, with a trunk as 

 thick as a man's body, flowering tufts of I*liorm'mm ieiiax, bushes of blue- 

 flowered Ilydrangi-as growing by dozens like Willows by the stream-siile, 

 Aponoijelon diduchymn producing copious flowers and fruit, acclimatized 

 I'leris crelica, and IFoodwnrdia radicans, S(dnrj'mc;lla KruHssin)ia making 

 itself quite at home amongst the grass of the lawn mixed with indigenous 

 llypmim and PtagwcJiila, EcJwveria glauca growing out permanently in 

 beds with Canarian ScmpervicHm and Cape Mesembryanlhemuvis, and many 

 other interesting indications of what horticulture may accomplish in a 

 climate where the thermometer seldom sinks below freezing-point, and 

 bedding Geraniums {Pdanjoniam zonale) hist sometimes through winter 

 witliout drooping their leaves. 



In the following catalogue we have noted only those species which we 

 saw ourselves in an excursion of four days' duration, during which we 

 directed our attent ion specially to the dispersion of the mass of species, in 

 preference to spending our time in searching minutely for rarities already 

 recorded. At the time of our visit, of course some of the early-flowering 

 plants were no longer recognizai)le. For instance, we could not make out at 

 Caerthilian the three rare Trefoils {Buccoiil, atrictum, and Molh/erii) which 

 grow there in company on an exposed sandy bank, and are in perfection 

 in June. I liave noted also in their regular sequence several jilants which 

 we expected, i)ut failed to see, as many conunon species fall under this 

 head, and there can be no doubt that the desiderata of this Lizard flora 

 furnish one of its most remarkable characteristics. It is likely that the 

 plants which we failed to see are at most comparative rarities, but I hope 

 that those who follow us into the district will take our catalogue as a 

 basis, and place their additions to it upon record, aiul that botanists of 

 the P(Miinsula, residents and visitors, will bear in memory that an interest- 

 ing question in English botanical- geography, about which as yet very 

 little has been said, in addition to what Mr. Watson has summarized by 

 gathering together the plants of a strikingly eastern plan of dispersion 

 under his Cicrmanic type of distriijiition, is how many plants common 

 enough all through the centre of England run out more or less decidedly 

 in the south-west.
