10 GLEANINGS AND ORIGINAL MEMORANDA. 
those specimens are some with glabrous flowers, which have considerable affinity with Impatiens levigata 
Wall., but from which the present appears y distinct. Stem erect, ree to four feet high, rather stout 
succulent, semipellucid, striated, often red at the setting on of the leaves, very thick and much branched and rooting 
below. Leaves alternate, large, sometimes nearly a span long, ovate, acuminated, penninerved, pale beneath ; petiole 
long, and nearly a line broad, semiterete, margined, the margin bent, with more or less numerous long, soft, distant 
fimbrize tipped with a gland. Peduncles aggregate, axillary, single-flowered, much shorter than the petiole, a little 
enlarged upwards, and curved down with the weight of the flower. The size of the flower is about equal to those of 
Impatiens balsamina, and the colour is yellowish, much suffused with pink. The upper sepal (two united) is remarkable 
for a large green horn-like projection from the back ; the lower for being downy, and for the short, much-curved, 
green spur. This, like other tropical species of the genus, requires to be treated as a tender annual. If potted in 
light rich soil, and kept in a stove and well supplied with water, it attains a considerable size, producing thick side- 
branches, which in time assume a hard woody appearance. When placed in a favourable situation as regards shade 
en 
materially assist in supplying nourishment to the plant. As it flowers late, we fear it will not ripen seeds ; but it may 
be increased by cuttings, which root readily in the summer, but require much care in the winter, as they are liable to 
damp off.— Bot. Mag., t. 4623. 
471. SoPHRONITE, THE SPECIES OF. 
illustrated by the accompanying woodcut, may be useful both to cultivators and botanists. The genus was first proposed 
at fol. 1129 of the Botanical Register, under the name of Sophronia, afterwards at t. 1147 of the same work changed 
to Sophronitis. The original species named S. cernua, imported from Botofogo, a place in the neighbourhood of Rio 
Janeiro, was for a long time the only kind known in gardens, and appears to have since given rise to three other names, 
viz., S. isopetala, Hoffmannseggii, and mutans, the plants bearing which are not in any way distinguishable by the 
accounts their authors have published of them. A second species was added in the Sertwm Orchidaceum, with large 
scarlet flowers, under the name of S. grandiflora ; then in 1840 came a third with violet flowers, called S. violacea ; and a 
fourth, S. pterocarpa, has long lain buried in herbaria. A good generic character not having been yet published, we offer 
the following as one applicable to all the four species now known :— 
Perianthium explanatum, subæquale. Sepala et Petala imbricata, libera. Zabellum integrum, 
cucullatum, linguiforme, basi cum columna connatum, sæpiùs crist simplici transverså in medio 
lamellisque 2 axialibus. Columna libera, apice utrinque alata: alis integris conniventibus super 
cristam labelli. Stigma concavum, rostello obtuso. Anthera terminalis, opercularis, 8-locularis, 
cardine crasso inarticulato. ^ Pollinia 8, antice et posticé parallela, caudiculáà duplici pulvereà. 
— Herbe epiphyte (Brasilienses) monophylle, pseudobulbose, racemis axillaribus effusis paucifioris, 
floribus coccineis v. violaceis. : 
Of this the following are the species with their distinctive characters :— 
472, SOPHRONITIS CERNUA Lindley in Botanical Register, t. 1129; (alids 8. isopetala 
Hoffmannsegg in Botan. Zeitung, Y. 834; alias S. Hoffmannseggii Reichenbach Jil in Linnea Litt. 
Ber., XVI. 236; aliàs S. nutans Id. Ibid. 3) folio ovato-oblongo, racemo corymboso paucifloro, 
sepalis petalisque ovatis acutis, labello repando acuto, columnæ alis brevibus obtusissimis, ovario sex- 
costato. (Fig. 236; 8, a lip; 9, pollen masses ; 10, an end view of the ovary.) 
This plant has small brilliant scarlet flowers, with a yellow lip. 
The sepals and petals are of the same size. There 
not seem to be any essential difference in the plants now referre 
d here. The species is common in gardens, 
473. SopHRONITIS GRANDIFLORA Lindley Sertum Orchidaceum, t. 5, g. 2; (alias Cattleya 
coccinea Bot. Reg., fol. 1919;) folio oblongo acuto pseudobulbo ovali tereti longiore, floribus solitariis, 
spathá nulla, sepalis lineari-oblongis obtusis rectis, petalis triplo latioribus, labello ovato basi cucullato 
indiviso apice plano sepalis breviore. (Fig. 237.) 
Found by Deseourtilz, upon the high mountains that separate the province of Bananal from that of Ilha Grande ; by 
ardner, on trees near Rio Janeiro, on mountain heights, where rime frost is seen in the morning (659 and 5878 of his 
Herbarium). The finest of the genus. Flowers bright scarlet or cinnabar, three inches across ; lip yellow.
