Nipaul Gouania. Fl. June, Oct. Shrub cl. 



Cult. Gouania is a genus of insignificant shrubs, not worth 

 cultivating, except in general collections. They will all grow 

 freely in a mixture of loam and peat ; and ripened cuttings 

 will soon strike root if planted in a pot of sand plunged in heat, 

 with a hand-glass placed over them. 



XXVII. CRUMENA'RIA (from cruniena, a purse ; in allu- 

 sion to the thin, papery capsule). Mart. nov. gen. bras. 2. p. 

 68. t. 160. Brogn. mem. rhamn. p. 73. 



LIN. SYST. Pentandria, Monogynia. Calyx campanulas, 

 5-cleft, coloured above, with the tube connate to the ovary 

 below. Petals hood-formed. Stamens with inclosed, 2-lobed 

 anthers. Style 1. Stigmas 3. Capsule covered by the adnate 

 calyx, papyraceous, tricoccous ; coccula with winged margins, 

 1 -seeded, fixed to the central, 3-parted, filiform receptacle. A 

 small, annual plant, with decumbent branches, alternate, stalked, 

 cordate, quite entire leaves, furnished with twin stipulas at 

 their base. Peduncles axillary, jointed, solitary, or twin. Flowers 

 small, white. 



1 C. DECU'MBENS (Mart. 1. c. t. 160.). 0. S. Native of 

 Brazil, in grassy places by the sides of woods. This genus 

 does not differ from Gouania, unless in the calyx being campa- 

 nulate, and in its tube being free at the apex, as well as in the 

 disk being defective. However, it differs from every plant in 

 the present order in the stems being annual. 



Decumbent Crumenaria. PI. decumbent. 



Cult. This plant is not worth cultivating, unless in the 

 gardens of the curious. The seeds should be sown in a pot of 

 mould about the beginning of April, and placed in a hot-bed, 

 and when the plants are of sufficient size, some may be planted 

 in separate pots, others may be planted in the open border, 

 where they will probably ripen their seed. 



f Genera allied to Rhamnece, but are not sufficiently known. 



XXVIII. COUTIA (Couepi is the Guiana name of one of 

 the species). Aubl. guian. 1. p. 296. D. C. prod. 2. p. 29. 

 Cupia, Jaum. exp. Glossopetalum, Schreb. gen. no. 526. 



LIN. SYST. Pentandria, Telra-Pentagynia. Calyx small, 

 5-toothed, permanent, adhering to the base of the ovary. Petals 

 5, oblong, appendiculate inside. Stamens 5, very short. Ovary 

 roundish, crowned by 4 or 5 sessile stigmas. Berry pea-shaped, 

 4-5-celled, 4-5-seeded. Trees with alternate, feather-nerved, 

 somewhat unequal stipulate leaves, axillary peduncles, bearing 

 numerous, umbellate pedicels and small flowers. This genus 

 should probably be placed in Rutaceee. 



1 G. GLA'BRA (Aubl. guian. 1. t. 116.) leaves quite smooth. 

 Tj . S. Native of Guiana, in the woods of Sinemari. Glosso- 

 petalum glabrum, Willd. spec. 2. p. 1521. Flowers yellow. 

 Berries black. The natives of Guiana make canoes of the trunk 

 of this tree. 



Smooth Coupia. Tree 60 feet. 



2 G. TOMENTOSA (Aubl. 1. c.) leaves hairy on both surfaces. 

 Fj . S. Native of Guiana, in woods. Glossopetalum tomen- 



tosum, Willd. spec. 2. p. 1521. The bark and leaves are bitter. 

 The latter are used by the inhabitants of Guiana against inflam- 

 mation of the eyes. 



Downy Coupia. Tree 25 feet. 



Cult. Loam, peat, and sand is a good mixture for this genus, 

 and ripened cuttings will root if planted in sand under a hand- 

 glass, in heat.
