air as possible in mild weather ; for they only require to be 

 protected from the frost, being tolerably hardy; but ought 

 not to be much watered in winter. If planted during sum- 

 mer in the full ground, they will grow prodigiously rank and 

 large; as they also will if permitted to root into the ground 

 through the holes at the bottom of the pots, which should be 

 frequently moved to prevent it. Their flowers have no great 

 beauty, but, as their whole appearance is singular, they may 

 be allowed a place in collections of plants, especially as they 

 need little attention. It may also be raised from seeds. 

 See the next species. 



2. Tetragonia Decumbens ; Trailing Tetrayonia. Shrub- 

 by, frosty: leaves obovate ; fruits winged. This has larger 

 stalks than the preceding species, but they branch out in the 

 same manner, with the branches trailing upon the ground : 

 the flowers also are larger, and appear from July to Sep- 

 tember. Native of the Cape. This, and the first species, 

 may be propagated by seeds, sown on a gentle hot-bed or 

 warm border of light fresh earth, where sometimes they will 

 remain a whole year before the plants come up. When 

 they are about four inches high, take them tip, and plant 

 them in pots; treating them in the same manner as has been 

 directed for the cuttings. 



3. Tetragonia Herbacea ; Herbaceous Tetragonia. Her- 

 baceous, even : leaves ovate, petioled ; fruits winged. This 

 has large fleshy roots : it is smooth, and succulent, with 

 many decumbent, branched, annual leafy stems, and scat- 

 tered, ovate, more or less acute, entire leaves; flowers yellow. 

 Native of the Cape. This species never produces seeds in 

 England, but will grow from cuttings planted early in the 

 spring, with the same facility as the others. 



4. Tetragonia Hirsuta; Hairy Tetragonia. Herbaceous, 

 hirsute, procumbent : leaves ovate, villose; flowers axillary, 

 tern, sessile. Native of the Cape. i 



5. Tetragonia Spicata; Spiked Tetragonia. Smooth, her- 

 baceous, erect: lower leaves ovate, uppermost lanceolate, 

 smooth ; flowers racemed. Native of the Cape. 



6. Tetragonia Echinata; Hedge-hog Tetragonia. Herba- 

 ceous: leaves rhomb-obovate; fruits echinate. Root biennial; 

 stem herbaceous, dividing into diffused branches, rendered 

 angular by the petioles running down them, scarcely a foot 

 long. It flowers from May till August: the flowers are pen- 

 dulous, purple-stalked, appearing as if frosted, clothed with 

 crystalline bladders. Native of the Cape. 



7. Tetragonia Expansa; Horned Tetragonia. Herbaceous: 

 leaves ovate-rhombed ; fruits four-horned. Root fibrous; 

 stem divided from the bottom into many irregular, round, leafy 

 branches. The whole plant is studded with very minute crys- 

 talline dots; flowers yellow. Biennial, Native of New Zea- 

 land, by the sides of woods, in bushy sandy places; also 

 within the tropics, on the shore of the island Tongataboo, 

 and in Japan: though not used by the inhabitants, it is a 

 very good pot-herb. Captain Cook ordered it to be served 

 up boiled for his sailors every day at breakfast and dinner, 

 while they remained in port. This is very tender, and must 

 be kept in a stove: it can only be propagated by the 

 seeds. 



8. Tetragonia Crystallina ; Diamond Tetragonia. Herba- 

 ceous, frosty : leaves ovate, sessile ; fruits unarmed. Root 

 annual; plant a span high, the whole covered with crystalline 

 papillse; stem nearly erect, branched from the bottom; leaves 

 about two inches long, bright green; flowers of a dull orange 

 or tawny yellow, axillary. Found in Peru. It will only live 

 hero in a stove. 



Tetranthvs; a genus of the class Syngenesia, order Poly- 

 gamia-Segrcgata. GENERIC CHARACTER. Calix : com- 



mon five-leaved, four-flowered ; leaflets linear, erect, ciliate 

 at the base of the florets; perianth proper one-leafed, tubu- 

 lous, attenuated at the base, compressed, oblique at the throat, 

 ciliate at the edge, one-flowered, many times longer than the 

 common calix. Corolla: compound uniform, equal; corollets 

 four, hermaphrodite : proper one-petalled, funnel-form ; tube 

 gradually widening; border five-cleft, unequal; the two upper 

 segments smaller, and less divided, the three lower more 

 spreading, oblong, obtuse. Stamina: filamenta five from the 

 base of the corollet, half the length of the tube ; antherse 

 tubulous. Pistil: germen from the bottom of the perianth, 

 under the filamenta, oblong ; style longer than the stamina 

 and corolla, filiform, divided beyond the middle; stigmas 

 reflexed, linear, obtuse. Pericarp : none ; perianth proper 

 unchanged, permanent, including. Seed : oblong, striated, 

 crowned with the membranaceous ciliate margin of the apex. 

 Receptacle: very small, naked. ESSENTIAL CHARACTER, 

 Calix: common four-flowered; perianth proper, one-leafed. 

 Seed: one, crowned. The only species is, 



1. Terranthus Littoralis. A small annual herb, flowering 

 in the spring; flowers small, white. Native of Hispaniola. 



Tetraphis; a genus of the class Gryptogamia, order Musci.

 ple, of four pyramidal, erect, unconnected teeth. The 



species are, 



1. Tetraphis Pellucida; Transparent Four-toothed Moss. 

 Capsule cylindrical ; leaves ovate, acute, single-ribbed. Root

 places, about the roots of trees, in various parts of Europe.

 resembles the third species, but the plant is smooth ; root

 Levant and of Apulia, in moist ground. Sow the seeds in 

 the spring, whre the plants are intended to remain; when 

 they come up, thin them where they are too close, and keep 

 them clean from weeds. They ripen their seeds in the first 

 year; but in a warm situation will live through the winter.
