60 EXTRACTS. 



1 hey, therefore, should be kept in winter in a cool airy place, where a perfect 

 command of ventilation is possessed ; and the temperature should not be 

 allowed to rise much above 40 or 45 degrees in the winter months. Upon 

 the above plan, Mr. Knight manages the young plants obtained from the 

 collections formed by Mr. Baxter, and with such success that no doubt cau 

 be entertained of its excellence. Increased by cuttings or seeds; soil, sandy 

 peat. Gompholobium, from Gomphos, wedge; and lobus, pod. Shape of 

 seed, pod. 



4. Clarkia elegans, Californian Clarkia, Octandria, Monogynia. Onagrariae. 

 The name of Clarkia, like that of Rose, carries a charm with it, fur it is im- 

 possible not to associate with it, the idea of that sweet North American flower, 

 which is now the ornament of every flower market from London and Paris, 

 to Moscow and Stockliolm. The present very beautiful species was found in 

 California, by Mr. Douglas, and was raised in 1832, in the Garden of the 

 Horticultural Society, and blossomed from Jul}' to October. Flowers, of a 

 fine rosy purple, not quite as large as C. pCilchella. The plant grows two 

 feet high. Culture. Increased annually by seeds, or kept perennial by slips 

 taken off early in September, and placed in a greenhouse during winter; soil, 

 rich loam. Clarkia, so called after Captain Clark, who accompanied Captain 

 Lewis, to Rocky Mountains. 



5. Calceolaria Hcrberlicina ; var. parviflora. Mr. W. Herbert's Calceolaria, 

 small flowered variety. Diaudria, Monogynia. Scrophularincae. The present 

 variety was raised from seeds found by Mr. Cuming, near Valparaiso. The 

 plant flowered in the Garden of the Comte de ^'andes, in May, 1832. The 

 flowers are smaller than C. Herberliana, more densely corymbose and numer- 

 ous, and the tip, which is less inflated, has three distinct projections, which 

 give it a sort of plaited appearance. Colour, yellow, streaked with orange. 

 Culture. The same as C. chiloensis, integrifolia, &c. that is to say an open 

 border in a dry sheltered place in summer, and a greenhouse in winter. 

 Calceolaria, from Calceolus, a slipper form of corolla. 



6. atendctis speciusa, shewy Stenactis ; Syngenesia, Polygamia Superflua. 

 Compositae. A hardy perennial, native of California, sent from thence by 

 Mr. Douglas, to the London Horticultural Society. The flowers are very 

 handsome and shewy. A bed of it would have a splendid appearance. It 

 grows two feet high, and flowers from July to October. Although a perennial, 

 seedlings flower very freely the first year; and so eai'ly as to perfect abun- 

 dance of seeds, and may be thus treated as an annual. Flowers, from tKO to 

 three inches across; the colour of the ligulate petals of the Ray, are dark 

 violet, and the Disk is a deep yellow. Culture. Increased by seeds, or divi- 

 sion of the plaut ; soil, rich loam. Stenactis, apparently from Stena to sigh, 

 the application we do not know. 



7. PhnclJa hhp'ida, long stalked Pimelea. Diandria, Monogynia. Thy- 

 melea. A beautiful greenhouse shrub, native of New Holland, discovered by 

 Dr. Bkown. It is nearly allied to the Pimelea rosea, to which it is superior 

 in beautv, and from which it is readily kuowu by its broader leaves, larger 

 flower heads, and especially by the long slifBsb hairs that clothe the base of 

 the calyx densely, and the apex sparingly, so as to give the flowers the aspect 

 of delicate feathers. These hairs are long, very transparent tubes, with a con- 

 siderable number of minute particles within their cavity; they are doubtless 

 extremely well adapted to shew distinctly that curious motion in the fluids of 

 plants, which forms so singular a species of circulation in their system, and 

 which seems to be universal in hairs, so long as they are alive. Flowers, rose 

 coloured. Culture. Increased by cuttings, struck in sand ; soil, sandy peat, 

 ijee No. 3. Pimelea, from Pimele, fat.
