GLEANINGS AND ORIGINAL MEMORANDA. 



Citrus trifoliata. Sir J. D. Hooker. This is a free flowering, handsome shrub, 

 evergreen, but annually casts its leaves. It comes from Japan, and has been grown in 

 a sheltered border at Kew for a good many years uninjured by frost ; it is not so well 

 known as it deserves to be. It blooms in spring, at which time its pure white flowers 

 are very effective. Like most others of the Citrus family, it will, no doubt, thrive in 

 any ordinary free soil, such as a mixture of free loam and peat. 



A glabrous shrub with stout spreading terete smooth green shining branches, and straight thorns an inch 

 long and upwards. Leaves appearing after the flowers, three-foliate ; petiole about half an inch long, flattened ; 

 leaflets elliptic, sessile, crenulate, obtuse, emarginate, coriaceous, dotted with pellucid oil glands ; lateral often 

 oblique, about an inch, the terminal one and a half inch long. Flower solitary in the axils of the spines, shortly 

 pedicelled, about an inch in diameter. Sepals four or five, small, oblong, concave, deciduous. Petals four or five, 

 two-thirds of an inch long, obovate, almost clawed, concave, incurved, snow-white. Stamens eight or ten, inserted 

 in a thick annular pubescent disk ; filaments flattened, connate at the base, reddish below the middle. Anthers 

 oblong. Ovary globose ; stigma short, crenate ; ovules one to each cell. — Botanical Magazine, 6513. 



Sagenia Lawrenciana. Moore. A very fine Fern from Madagascar, where it grows 

 in the shade of dense forests in a humid atmosphere. Mr. L. Humblot, who discovered 

 it, describes it as " a splendid Fern, with a trunk or caudex three to four inches in height, 

 the fronds attaining a length of two feet or more, and spreading gracefully from the crown/' 

 The country it comes from, although it is found at a considerable elevation, points to its 

 requiring a moderately warm house to grow it properly ; in other respects it will, no doubt, 

 succeed with ordinary treatment. 



Fronds very large, ovate acuminate, glabrous, pinnate below, pinnatifid above ; pinnae all somewhat falcate, 

 and distinctly acuminate, the lower ones obliquely deltoid, much enlarged on the posterior side, deeply pinnatifid 

 near the base, becoming sinuately lobed upwards ; upper ones oblong-acuminate, the larger entire on the upper, 

 sinuately lobed on the lower margin, confhient, with a narrow sinus, gradually smaller upwards, entire ; racbides 

 and costse glossy black, very distinctly marked on the under surface, strigose above ; veins compoundly anasto- 

 mosing, the primary ones pinnately disposed, parallel-curved in an upward direction, running out into the 

 reticulations of the margin, somewhat flexuose, about half an inch apart in the middle entire segments, more 

 widely separated (one inch) in the middle parts of the lower pinnae ; secondary veins in three to four irregular 

 series between the primaries ; tertiary veins forming a close network with numerous free divaricate veinlets in the 

 ultimate areoles ; sori large, mostly confined to a row on each side the primary veins, within or on the border 

 of the primary areoles, compital ; indusium broad cordate -reniform.— Gardener's Chronicle, N.S., vol. xv., p. 9. 



Crinum purpurascens. /. G. Baker. A tender stove Amaryllid from the west coast 

 of Africa, requiring heat to grow it. It would appear to be found in both Fernando Po 

 and Old Calabar. It belongs to the C. amcenum and C. Americanum section of the family,
