Telo'pea. — Proteacece. — The 

 "Warratah, — The brilliant scarlet 

 flowers of this plant, which are con- 

 spicuous even at a great distance, are 

 j said to have been one cause why the 

 ! coast of New South Wales was dis- 

 ' tinguished by its first visitors as 

 I Botany Bay, in allusion to the great 

 ! accession to botany likely to be de- 

 I rived from a country where the plants 

 I appeared so diflerent to those of 

 j Europe. Theflowerof the Warratah 

 may be compared to a gigantic head 

 I of clover ; of the most intense and 

 ; brilliant scarlet ; but it is not com- 

 j mon in England, probably because it 

 I is a very difficult plant to manage. 

 I The first jjoint to be attended to is 

 I to have the pot in which it is grown 

 j thoroughly well drained ; and the 

 { next to allow it abundance of light 

 and air. It is generally kept in a 

 stove in England ; but it succeeds 

 better in a greenhouse, at least during 

 i the summer months ; as it is very apt 

 to become covered with insects if it is 

 kept all the year in a hothouse. It 

 is propagated by cuttings or suckers, 

 which it throws up in abundance ; 

 and it should be grown in heath- 

 mould, mixed with white sand and a 

 little loam. It should be regularly 

 watered in the flowering season ; but 

 it may be kept almost dry during the 

 winter months. 



Teno'ria. — UmhelUferce. —The 

 shrubby species of Hare's Ear. — See 

 Bupleu'rum. 



Tenthre'do. — See Saw-fly. 

 Tephri'tis. — A kind of leaf- 

 mining insect, which attacks celery 

 and chrysanthemums ; the perfect 

 insect is a fly which has a very 

 pecrdiar sideling motion in flying, 

 quite difi"erent to most other flies. 

 From the small size of these flies, it 

 is extremely difficult to catch them 

 by hand, and Mr. Westwood sug- 

 gests hanging lines of string covered 

 with birdlime over the rows of 



celery. The gi-ubs may also be 

 crushed by the hand in their pas- 

 sage through the leaf without de- 

 stroying the leaf, and if this be done 

 in the beginning of the summer, the 

 destruction of one grub at that pe- 

 riod will prevent the production of 

 a numerous progeny. 



Testudik a'ria. — Bioscoriece. — 

 Elephant' s-foot, or Hottentot Bread. 

 — A very singular plant, with au 

 enormous scaly root above ground, 

 from which issues a slender stem, 

 with small flowers. The plant is a 

 native of the Cape, from which 

 country the roots are frequently re- 

 ceived. It should have a season of 

 complete repose, without any water 

 being given to it when it is not in a 

 growing state, and it should be 

 grown in a mixture of equal parts 

 of turfy loam, peat, and sand ; the 

 large scaly root being placed on the 

 surface of the soil, and not buried 

 in it. The earth in the pot should 

 be then watered and kept moist till 

 the fibrous roots begin to appear, 

 after which less water should be 

 given till the slender stem appears, 

 when the soil in the pot should be 

 watered regularly and abundantly ; 

 but no water should ever be poured 

 on the scaly root. The flowers are 

 dioecious, and have never yet pro- 

 duced seed in England. The sub- 

 stance of the scaly root is farina- 

 ceous, and it is said to be used by 

 the Hottentots as food. The plant 

 has never been propagated in Eng- 

 land ; all the plants grown in this 

 country having been received in the 

 state of dry roots from the Cape. 



Tha'lia. — Cdnnece. — T. dealbata 

 is an aquatic plant, a native of South 

 Carolina, with very curiousblack and 

 white fragrant flowers. It is about 

 as hardy as Cdlla cethiopica, and 

 requires the same treatment. See
