THE

THE 



two supposed species, T. Bohea and T. viridis, 

 are nothing more than varieties of one species, 

 for which Linneeus' name T. chinensis is adopt- 

 ed, and of which the Assam tea plant, sometimes 

 called Thea asswmica, is merely a third variety, 

 or perhaps, indeed, the wild type. The black 

 and green teas are, however, mainly the growth 

 of different districts of China, but the two kinds 

 may be produced in either district, the differ- 

 ence being caused solely by the diverse methods 

 of preparation. " 



Dr. Edward Smith, the most recent investiga- 

 tor of the action of tea, sums up its action thus : 

 — "It increases the assimilation of food, both 

 of the flesh and heat-forming kinds ; and with 

 abundance of food it must promote nutrition, 

 whilst in the absence of sufficient food it in- 

 creases the waste of the body."

Thelebolus, Tode. From thele, a, nipple, and 

 boleo, to eject. Linn. 24, Or. 9, Nat. Or. 

 Lycoperddcece. This species is found on cow- 

 dung, after rain, in June and July — stercdreus. 



Thelephora, Ehrhart. From theU; a nipple, 

 and phoreo, to bear ; in allusion to the papil- 

 lose surface of all the species. Linn. 24, 

 Or. 9, Nat. Or. Agaricacece. The species of 

 Thelephora are common upon old roots and 

 branches of trees. Synonymes : 1, Simdntia,

Thelotrema, Acharius. From thele, a nipple, 

 and trema, orifice ; the protuberances of the 

 thallus are perforated. Linn. 24, Or. 8, Nat. 

 Or. Graphidctcece. These plants are found on 

 the bark of trees — exanthem&ticwn, Sutchln-

 larioides, v. agelcewm. 



Thelygonum, from thelys, woman, and gonu, a 

 knee ; supposed resemblance in the joints.

 Common garden soil suits this species ; seeds 

 — cynocrdmbe. 



Theltmitra. Forster, who named the genus, 

 is said to have derived it from thelys, wo- 

 man, and mitra, a cap. Linn. 20, Or. 1, Nat. 

 Or. Orchidaeece. This is a tuberous-rooted 



genus, requiring precisely the same treatment 

 as Disa.

Theobr6ma, Linn. From theos, god, and broma, 

 food ; celestial food. Linn. 18, Or. 1, Nat. 



' Or. Sterculictcew. The species of Theobroma, 

 or chocolate-nut, grow well in a mixture oi 

 loam and peat ; and cuttings root readily in 

 sand, under a glass, in heat. Seeds do not 

 retain their vegetative power for a great length 

 of time. The seeds of T. OacAo furnish the 

 chocolate of the shops. The seeds are very 

 nourishing and agreeable to most people, and 

 are, therefore, kept in the majority of the 

 houses in America as a necessary part of the 

 provisions of the family. See Quaz&nia.

Theofbrasta, Linn. Named after Theophras- 

 tus, the father of natural history. Linn. 5, 

 Or. 1, Nat. Or. Myrsinaceee. A small, hand- 

 some tree, with a tuft of long, evergreen 

 branches at the top of its simple stem, some- 

 thing like a palm-tree. It is well worth cul- 

 tivating, on account of its long, holly-like 

 leaves. A mixture of peat, loam, and sand, 

 suits it best ; and cuttings, with the leaves 

 entire, root readily in sand, under a glass, in 

 heat. Bread is said to be prepared from the 

 pounded seeds of this tree in St. Domingo, 

 where it is. called Le Petit Coco. See Olavlja.

Therm6psis, E. Brown. From thermos, a lupine, 

 and opsis, resemblance ; because of the resem- 

 blance of the species to lupines. Linn. 10, 

 Or. 1, Nat. Or. Fabacece. The species of 

 Thermopsis are very elegant, but rather diffi- 

 cult to preserve. They succeed best in a light, 

 rich soil ; and the safest way of increasing 

 them is by seed ; for when the plants are sepa- 

 rated at the roots they are very liable to suffer.
