TAG 



^achiade'nus. From Tachia, a genus of the 

 same order, and aden, a gland ; tlie ovary is 

 surrounded by a ring of glands as in Tachia. 

 Nat. Ord. Gentianacece. 



A genus ot herbaceous or somewhat shrubby 

 plants, natives of Madagascar. T. carinatus 

 is a pretty, green-house annual, closely re- 

 lated to Chironia, Liaianthus and Exacum, and 

 was introduced by the Rev. William Ellis in 

 1858, who brought seeds from Madagascar. 

 It grows freely, branches naturally at the 

 base, and attains the height of a foot or more. 

 The llowers are white, with the lobes of the 

 corolla bright-purple, produced freely in au- 

 tumn, and lasting over a month before fading. 

 Seeds should be sown in February and treated 

 like Gloxinias. 



Tacso'nia. From Tacso, the name of one of the 

 species in Peru. Nat. Ord. Pasaifioracets. 



A genus of very beautiful climbing plants, 

 closely related to Pasaiflora, having the same 

 general appearance, and the same structure 

 of stamens, pistils and fruit, but differing in 

 the usually long, cylindrical tube of the calyx, 

 which is furnished with two crowns, one at 

 the throat, and the other near its base. In 

 T. manicata, however, a very handsome 

 species, the tube scarcely exceeds in length 

 that of a Passion Flower. The species are 

 natives of Central America and the West 

 Indies. The fruits of several of them, as T. 

 molliaaima, T. tripartita and T. speciosa. are 

 edible. T. Buchanani is Paaaiflora vitifolia, 

 and is one of the most beautiful plants of the 

 order. The Tacsonias are all beautiful plants 

 and worthy a place in any collection. They 

 require the same general treatment a5 Passi- 

 Aora, and are propagated in the same way. 



Taeni'tis. From tainia, a fillet or ribbon ; allud- 

 ing to the linear pinnse. A small genus of 

 interesting stove ferns, all tropical, but not 

 very closely allied. They differ principally 

 from Tceniopsis and Viltaria in their fronds 

 being all net-veined. 



Tage'tes. Marigold. From the beauty of its 

 flowers, this genus was named after Tagea, a 

 Tuscan divinity. Nat. Ord Compoaitm. 



Marigolds are old favorites in our gardens, 

 particularly those known as African and 

 French Marigolds. The former (T. ered,a) 

 have uniformly large yellow or orange-colored 

 flowers, and usually attain a couple of feet in 

 height ; the latter (T. patula) are more dwarf, 

 and have their flower's striped of a deep 

 brown-purple and yellow. They are all showy, 

 .especially in masses, and are effective for dis- 

 tant groups. There is, however, another 

 species, T. aignata pumila (syn. T. tenuifoUa), 

 preferable for bedding ; it is more compact in 

 habit ; and though its flowers do not boast the 

 "Vivid coloring of the French Marigolds (being 

 entirely yellow), yet they are produced in 

 such long succession as to amply compensate 

 for the deficiency ; besides which, the scent, 

 so frequently complained of in the others, 

 is in this so much reduced as to be no longer 

 unpleasant. T. lucida, the sweet-scented, 

 Mexican Marigold, is also occasionally grown 

 in gardens and is very showy. These com- 

 prise all that are worth cultivating as orna- 

 mental plants, and require precisely the same 

 treatment as other hardy annuals. 

 Talau'ma. The native name of the South 

 American species. Nat. Ord. Magnoliacex. 



TAM 



A genus of trees or shrubs remarkable for 

 their fine, fragrant flowers. There are about 

 fifteen species, four of which are natives of 

 tropical America and the rest of Asia and 

 Japan. Six or more species are in cultivation, 

 but are found only in large collections. Prop- 

 agated principally by layers. 



Taliga'lea. Said to be the native name in 

 Guiana. Nat. Ord. Verbenacece. 



Amaaonia is now the correct name of this 

 genus. (See Amasonia.) 



Tali'jiuta. Supposed to be from thalia, a green 

 branch ; referring to its durable verdure. 

 Nat. Ord. PortulacacecB. 



A genus of annual and biennial, succulent 

 plants, inhabiting the warmer parts of both 

 hemispheres, but chiefly conflnedto sub-tropi- 

 cal America. T. patena, and its variety with 

 variegated foliage, a native of Brazil, is a 

 desirable plant for the border, or as a basket 

 or vase plant, being well adapted to stand hot, 

 dry weather, and does not suffer badly if 

 neglected. The variegated variety is often 

 used as a white line for ribbon borders. This 

 species is used in Brazil as a pot-herb, and 

 is readily propagated by seeds or cuttings. 

 Introduced in 1776. 



Talipot Palm. See Corypha umbraculifera. 



TallQ-w Shrub. A common name for Myrica 

 cerifera. 



Tallow Tree. See Stillingia. 



Tamarack. American or Black Larch, Hack- 

 matack. See Larix Americana. 



Tamarica'ceae. A natural order of shrubs or 

 undershrubs, found chiefly in maritime sands 

 or gravelly places near rivers, in the 

 temperate and warmer regions of the north- 

 ern hemisphere, and also in South Africa. 

 The two principal Asiatic and European gen- 

 era, Tamarix and Reaumuria, are regarded by 

 some botanists as types of distinct orders ; 

 and the splendid Mexican genus, Fouquiera, 

 differing chiefly in the large petals, united 

 into a tubular corolla, has only lately been 

 associated with the TamaricacecB as a third 

 tribe. 



Tamarind. See Tamarindua. 



Tamari'ndus. Tamarind Tree. Tamar, in Ara- 

 bic, is the name of the Date, and Indua, In- 

 dian, literally Indian Date. Nat. Ord. Papi- 

 lionaceoB. 



The tree that furnishes the Tamarinds lor 

 preserves is a native of the East and West 

 Indies, Egypt and Arabia. It is a large, 

 spreading and beautiful tree, and its grace- 

 ful, pinnated foliage, and racemes of fragrant 

 flowers, which are yellow striped with red, 

 and its purple stamens, give it an elegant ap- 

 pearance. T. Indica is the only known spe- 

 cies, and this varies but little in the different 

 countries in which it abounds. Propagated 

 frcrr- "iuttines and by seeds. Introduced in 

 1633. 



Ta'marisk. See Tamarix. 



Ta'marix. Tamarisk. From Tamaria, novr 

 Tambro. the name of a river where it grows, 

 on the borders of the Pyrenees. Nat. Ord. 

 TamaricacecB. 



Tall-growmg shrubs, mostly natives of Eu- 

 rope. A great many species are enumerated, 

 but two only are usually met in collections of 

 ornamental shrubs. These are T. Oallica,
