 {Hotrytxit'tidrum ShirUiirii. Hook.), the I'rKA, is one of 

 the rarest plants in New Zeal., but is considerably 

 planteil in the northern part where it makes a striking 

 round-headed evergreen tree to 2.') ft. high, with large 

 oblong or obovale shining Ivs. crowded near the ends 

 of the branches and tenninal stout panich-s of greenish

 It is intro. in England, and is well worth trying in Calif.

MESEMBRYANTHEMUM (Greek, midday flower; 

 the flowers usually opiii in sunshine and close in 

 shadow). 8ometuncs spelled Mcsctiihrianlhcmuni. 

 Aizoaces-. Fio-m.^kicold. Mostly low -growing .suc- 

 culents, grown as pot subjects under glass or in window- 

 gardens and sometimes planted out in .sununer; some 

 kinds are good bank-covers in mild climates. 



Annual or perennial i)rostrate or erect herbs, and 

 sometimes subshrubs, with thick fleshy usually ojjpo.site 

 Ivs. which are :i-angled, terete or flat, and with entire 

 or more or less spiny margins: fls. white, red or yellow, 

 mn,stly terminating the branches, usually opening in 

 full Sim but a few expanding in the evening; calyx 

 mostly o-parted, the lobes usually If .-like and unequid; 

 petals very many, linear, in 1 to man>' rows, united at 

 the base; stamens verj- numerous, also in many rows 

 and united at base; ovary mostly .3-celled (but variable) : 

 caps. 5- to many-celled, "stellately dehiscing at the sum- 

 mit, becoming baccate, hygroscopic; seeds very numer- 

 ous.— Mescmbrjanthemum inehides .some 300 and more 

 species, nearly all of which are S. African, according to 

 Sonder "abounding throughout the arid plains and 

 sands of the whole country to the south of the Orange 

 River and west of the Great Fish River." Four .species 

 are described by Bentham in Flora .Australicnsis. Two 

 (.1/. crygtaltinum and M. fquilalerali) are native in Galif. 

 Others occur in New Zeal., Canaries, Ar.ibia and the 

 Medit. region. They are allied botanically to the cacta- 

 ceous series, although lacking the spines of those plants 

 and bearing tme Ivs. Ilorticulturally, they are fanciers' 

 plants, and are clas.sed with "succulents." Very few arc 

 in the general trarie, although a number are adviTtised 

 in Calif, and others are in botanic gardens. As with 

 most succulents, the .species are not well understood 

 botanically, owing largely to the difficulty in luaking 

 herbarium .specimens. Many of them are" of odil and 

 grotesque form. One species, M. cryntfitHnuw, is a 

 common hou.s<;-plant, being known as ic(>-plant, but it 

 is one of the least showy in fl. It is grown for the thick 

 gli.stening foliage. It prop, readily by seed or division. 

 The best available account of the mesembrvanth(!iimms 

 is Sender's elaboration of the S. African "spcci(« (293 

 numbers; in Flora Capensis, Vol. II (18()l-2), from 

 which the following treatment has b{;en largely taken. 

 Sfmder writes th.'it "the caps, are tightly closed in dry 

 weather and open naturally after rain. If thrown into 

 water until it becomes thoroughly soakt'd an<l then 

 removed, an old caps, will open out its cajiillary valv(;s, 

 ra'liating from a center like a star; and will do.se tliem 

 again when dry. Thi.s experiment may be repeated 



several times without destroying their remarkable 

 hygronictric iirojierty." 



In s\nmy and semi-arid regions the fig-marigolds arc 

 very ajiiirojiriatc and attractive, covering the soil with 

 lilumji foliage and giving a display of brilliant colors. 

 Tlicy arc also used more or less in bedding-out on south 

 borders and exposures in cooler and moister climates. 



2364. Mesembiyanthemum f elinum. ( X H) 



M. edule has extensively run wild in many parts of the 

 world and is useful in covering banks and holding loose 

 sands. It withstands some frost. Any number of spe- 

 cies may be found in the collections of fanciers, and 

 riiany not described below arc mentioned in periodical 

 literature, but they need not be entered here as they 

 are really not horticulturally known. See Succulents. 



The cultivation of the fig-marigolds should consider 

 their natural conditions. They are found in their native 

 habitats growing most lux-uriantly on dry barren rocky 

 places and on dry sandy plains. They are succulent 

 plants with thick fleshy leaves, and are therefore able 

 to stand the severe drought they have to put up with in 

 those arid places. Knowing that these plants delight in 

 dry arid situations gives the key to their cultivation. 

 When gro\vn in pots, care should be taken that the pots 

 are well drained. A light sandy loam, mixed with 

 brick rubbish broken small, makes a good compost 

 for them. In summer they may be placed out-of-doors 

 in a slightly elevated and sunny position, where they 

 will ))roduce an abundance of their showy blossoms. 

 On the approach of cold weather in autumn they may 

 be placed in a cool greenhouse with a dry atmosphere 

 and plenty of air. Very little water is needed during the 

 dull months of winter. Some of the species make good 

 window plants. M. cordifolium var. variegatum is largely 

 grown for edgings for beds. M. ■pomeridianum and M. 

 Iricolorum are good showy annuals. Propagation is 

 effected either by cuttings or by seeds. Cuttings should 

 be dried in the sun for two or three days before they 

 are inserted in s.and. (Robert Cameron.) 



In the following account, the species are all South 

 African unless otherwise specified.
