the larger proportion of the original fat retained, while 

 the so-called "Cocoa" preparations are the same ma- 

 terial in fine powder, sweetened or unsweetened, but 

 with the greater proportion of ^lie Cacao fat extracted. 

 This fat, when clarified, is a pure white substance, 

 almost as hard as beeswax, and is used in many phar- 

 maceutical preparations. Chocolate and Cocoa are Ijnth 

 made from the beans or seeds of Theobroma Cacao ami 

 T. pentarjoiia, and only differ in the method of prepara- 

 tion. 



The word "Cocoa" is a market corruption of the 

 original Spanish "Cacao," which was adopted by Tournc- 

 fnrt as a generic name but has since been disphiced 

 by the Limia-au Theobroma. j. H. Hart. 



THEOPHRASTA {Tlieo|-.lirastus was a Greek natural- 

 ist an.l plulosopber, :{7U-:Jy.'') B.C.}. Myrsiiutcecf. Ac- 

 cording to Benthain A: Honker, this genus has but a 

 single species, T. Juss/mi, of San Domingo. J. De- 

 caisne, in Annalcs (k-s Sciences Naturelles for 187G 

 (ser. G, Bot. :i) contrasts three species. Pax, in Engler 

 6c Prantl's "Ptianzenfamilien," written later than either 

 of the above, recognizes four species- Five names 

 occur in the American trade, only one of which is a 

 true Theophrasta according to either of the above 

 autliorities. This is T. JnssieuL Three of them an.; 

 to be referred to the related genus Clavija, and one {T. 

 hnperialis] is now regarded as a species of Chryso- 

 phyllum (of the family Sapotacefe). The chief technical 

 differences between Theophrasta and Clavija are in the 

 flowers and fruits. In Theophrasta the corolla is cyl- 

 indrical and shallowly 5-lobed; staminodia attached on 

 the base of the corolla: fr. large and many-seeded. In 

 Clavija the corolla is subrotate and deeply 5-cleft; 

 staminodia attached on the tube of the corolla; fr. 1- 

 many-seeded. Theophrasta itself includes a glabrous 

 shrub with erect, nearly simple stem, the simple Ivs. 

 crowded at the ends of tlie branches, the fls. large, 

 wliite, in racemes. The fls. are perfect and gamopeta- 

 lous; calyx and corolla with 5 divisions that are imljri- 

 cated in estivation, the corolla bearing a corona in the 

 throat; stamens 5, fixed at the bottom of the corolla- 

 tube; pistil one, with short style and capitate stigma. 

 Fr. fleshy and apple-like, many-seeded. The species 

 referred to Theophrasta in the American trade are 

 handsome large foliage plants for warmhouse culture. 

 An allied genus is Jacquinia, wliich see. 



The following cultural note is probably applicable to 

 the various species cultivated under the name of Theo- 

 phrasta: According to T. Baines in Gn. l:;-:9."». T. im- 

 perialis is of easy cultnre, enduring a winter tempera- 

 ture of i')'^ without injury but making the best growtli 

 with 70° night temperature and 10° rise during the day. 

 It has the objection of being almost impossible to ro(;t 

 from cuttings. A plant that has become too large may 

 have part of the top cut off and all the buds removed from 

 the stem down to within a few inches of the groun<l, 

 wliich operation causes the plant to sprout from the 

 base. One only of the sprouts should be left; when it 

 is well started the old stem may be cut down and after 

 waiting until a little more growth has been nuide the 

 plant should be taken from the pot, and be cleaned of 

 soil and dead roots and repotted.

L. H. B. 



Tn^nUdFSlS {Greek, lupine-Ul-e). Legumindscp. A 

 genus of al)Out 15 species of perennial herbs native to 

 North America and northern and eastern Asia. They 

 are erect plants with large. 3-foliolate, stipulate leaves 

 and showy yellow or purple flowers in terminal or axil- 

 lary racemes. The following species are all handsome 

 hardy perennials bearing yellow flowers in early to late 

 summer. They are not particular as to soil or position, 

 but do best in a deep, light, well-drained soil. They 

 are generally deep-rooted plants and endure drought 

 very well. 



Propagation may be effected by division, especially 

 in T. montana, T. fabacea and T. rhomhifiilia, which 

 spread extensively by the root, but in general tlie better 

 way is by seed, although the seed is rather slow to ger- 

 minate and should be sown as soon as ripe or in the 

 spring with some heat.
