It is a native of the Cape, and appears to have been long possessed by the Dutch, as its Generic Character taken from D. V. ROYEN, is printed in the Genera Plantarum of LINNAEUS in 1764. There are only two known species, and they vary in the number of their Stamina, and divisions of the Corolla. [148] PELARGONIUM BETULINUM. BIRCH-LEAV'D CRANE'S-BILL. _Class and Order._ MONADELPHIA HEPTANDRIA. _Generic Character._ _Cal._ 5-partitus: lacinia suprema definente in tubulum capillarem nectariferum, secus pedunculum decurrentem. _Cor._ 5-petala, irregularis. _Filamenta_ 10, inaequalia: quorum 3 (raro 5) castrata. _Fructus_ 5-coccus, rostratus: rostra spiralia, introrsum barbata. _L'Herit. Geran._ _Specific Character and Synonyms._ PELARGONIUM _betulinum_ umbellis paucifloris, foliis ovatis inaequaliter serratis laevigatis. _L'Herit. n. 84._ GERANIUM _betulinum_ calycibus monophyllis, foliis ovatis inaequaliter serratis planis, caule fruticoso. _Linn. Sp. Pl. p. 946._ _Burm. Ger. 38._ GERANIUM fruticosum, betulae folio, africanum. _Raii Suppl. 513._ [Illustration: No 148] Though long since described, we have been in possession of this species of Crane's-Bill but a few years; it is one of the many new ones introduced by Mr. MASSON from the Cape, and at the same time one of the most desirable, as its blossoms which are ornamental, are freely produced during most of the summer, and the plant itself is readily propagated by cuttings. The flowers vary considerably, both in size, and colour; its foliage is different from that of most others, and, as its name imports, like that of the Birch-Tree. It requires the same treatment as most other Green-House Plants. [149] ZINNIA MULTIFLORA. MANY-FLOWERED ZINNIA. _Class and Order._ SYNGENESIA POLYGAMIA SUPERFLUA. _Generic Character._ _Recept._ paleaceum. _Pappus_ aristis 2 erectis. _Cal._ ovato-cylindricus, imbricatus. _Flosculi_ radii 5-10, persistentes, integri. _Specific Character and Synonyms._ ZINNIA _multiflora_ floribus pedunculatis. _Linn. Syst. Veg. ed. 14. Murr. p. 777._ [Illustration: No 149] The _Zinnia, multiflora_, a native of Louisania, is a plant of more modern introduction, but requires the same treatment, and flowers at the same time, as the _Tagetes patula_, with which, though far inferior in brilliancy of colour, it contributes to decorate the borders of the flower-garden from June to September. There is a variety of it with yellow flowers, nearly as common in our gardens as the present plant. LINNAEUS gave to this genus the name of ZINNIA, in honour of JOH. GOTTFR. ZINN, the pupil of HALLER, and his successor at the University of Gottingen. The plant we have figured, answers to the name and to the specific description of LINNAEUS'S _multiflora_; having never seen his _pauciflora_, we cannot say whether there be any just cause for suspecting them to be varieties of each other.
