TANGELO 



dreds of additional hybrids between 

 all the mandarin types of orange 

 (Citrus nobilis) such as the tanger- 

 ine, willow-leaf mandarin, King, 

 Satsuma, and the like, and the 

 better sorts of grapefruit and pum- 

 melo (Citrus grandis). These fruits 

 in general resemble round oranges 

 (Citrus sinensis) more than either 

 of their parents and are exceedingly 

 variable, sister fruits from seeds of 

 a single cross-pollinated fruit often 

 being very unlike. Among the 

 tangelos there are some of much 

 promise because of their superior 

 flavor and juiciness. 



The spread of citrus canker (a 

 bacteria] disease caused by Pseudo- 

 monas citri) to many of the hot 

 moist orange-growing regions of the 

 world makes it desirable to breed 

 new types of tangelos by hybri- 

 dizing the canker-resistant man- 

 darin oranges with canker-resis- 

 tant pummelos such as can be 

 found in the Orient. Such tan- 

 gelos, if canker-resistant, could 

 perhaps be grown in place of 

 the more susceptible round 

 oranges, just as limequats can 

 be grown in place of the com- 

 mon lime, which is very suscep- 

 tible to canker.

TANSY (Tanacetum vulgar e, 

 Linn.). A coarse-growing her- 

 baceous perennial naturalized 

 from middle Europe, and a famil- 

 iar occupant of old gardens, 

 waste places, and roadsides. Its 

 common name is said to be 

 derived from athanasia, immor- 

 tality, an idea suggested to the 

 ancient Greeks by the character- 

 istic permanent possession it 

 takes of the soil. Its annual 

 upright usually unbranched 

 stems, which rise about 3 feet 

 from the perennial root, bear 

 greatly divided deeply cut com- 

 pound bitter aromatic leaves 

 and rather dense corymbs of 

 numerous small yellow flower- 

 heads which appear in mid- 

 summer. The seed, which is 

 small, is marked by five rather 

 prominent grayish ribs and 

 retains its vitality for about 

 two years. Formerly its leaves 

 were in great favor as 

 a seasoning for various 

 culinary preparations, 

 especially puddings 

 and omelettes, uses 

 now almost obsolete. 

 By the medical profes- 

 sion, its tonic 'and 

 stimulant properties 

 and its efficacy in 

 hysterical and dropsi- 

 cal disorders are still 

 recognized, although 

 other medicines are

TAPISCIA 



more popular. In domestic practice 

 it played an early r61e as an anthel- 

 mintic and stomachic and is still 

 somewhat popular as a local agent 

 to relieve the pain of muscular 

 rheumatism, bruises, and chronic 

 ulcers. The wild plants usually 

 satisfy all demands, but when no 

 wild supply is at hand seed may be 

 used to start the half-dozen speci- 

 mens that a family should need. 

 Easily started, readily transplanted 

 or divided, tansy requires no special 

 care in cultivation except to keep 

 it clear of weeds and to prevent 

 its spreading and thus becoming 

 troublesome. It will thrive in 

 almost all soils and situations that 

 are not too wet. For botanical 

 account, see Tanacetum.

TAPEINOTES (from the 

 Greek, referring to its low 

 stature). Gesneriacese. Under this 

 generic name, one species is listed 

 abroad, T. Carollnse, Wawra. 

 The genus is now included in 

 Sinningia and the current name 

 is S. Carolina, Benth. & Hook. 

 (S. barbdta, Nichols.). It is a 

 Brazilian plant, adapted to the 

 warmhouse: decumbent or as- 

 cending, with oblong to lanceo- 

 late crenate-serrate Ivs. 1 ft. or 

 less long and red beneath: fls. 

 white, red-marked inside, with a 

 contracted and hairy throat and 

 tube swollen at base. B.M. 5623, 

 which represents a striking plant 

 with Ivs. brilliant red-purple 

 beneath and curved hairy 

 deflexed white corollas 13/2 in. 

 long: described as a small under- 

 shrub. 



TAPIOCA: Manihot. 



TAPIRIRA (from a native 

 name in Guiana). Also spelled 

 Tajnria. Anacardiacese. A name 

 of disputed application. The 

 plant likely to interest horticul- 

 turists in this relationship is 

 Cyrtocarpa procera, from Mex., 

 described on p. 945, Vol. II. 

 Of Tapirira itself, distinguished 

 by 4-5 styles, those in the 

 pistillate fls. short, none is 

 probably regularly in cult. As 

 formerly denned, the species 

 are S. American, with a few 

 in Afr. and Asia, 8 or 10 in 

 number. Later authors restrict 

 the genus to S. Amer., 

 mostly to Brazil. Under 

 any definition, the 

 genus is probably 

 adapted to cult, only 

 on our southernmost 

 borders. 



TAPISCIA (anagram 

 of Pistacia, to which 

 it bears a strong re- 

 semblance, though 

 not closely related).
