as a greenliouse shrubby succulent plant, requiring tlie same 

 kind of soil and treatment as Eclieverias. It is easily increased 

 by cuttings, and seeds, which it ripens abundantly. 



When grown out of doors, though pretty, it is not a very 

 striking plant. It flowers in August. How it will look in a 

 greenhouse is not ascertained as yet. 



7. Gaura Lindheimeri. Engelmann, in Boston Journal of 

 Natural History, Vol. V. p. 217. Vilmorin, in Revue 

 Horticole, 3. ser. V. 41. t. 5. 



Raised from seeds received from M. Vilmorin in April, 

 1850. 



A branching herbaceous plant, growing from 3 to 4 feet high, 

 and producing an abundance of gay white and reddish flowers 

 during all the latter part of the year. The branches are long, rod- 

 like, naked except at the extremities where the flowers grow. 

 The lower leaves are deeply divided in a pinnatifid or sinuate 

 manner ; the upper are lanceolate and slightly toothed, the upper- 

 most of all are linear-lanceolate and entire. The flowers appear 

 in long virgate spikes, which frequently branch near the end. 

 The petals are pure white ; the flower-buds are long and slender, 

 green when young, a warm reddish brown just before expansion. 

 The seed-vessels are small sessile four-cornered nuts. 



A perennial, growing freely in any good garden soil, and 

 flowering from July to September. It is easily increased from 

 seeds, and is best treated as a half-hardy biennial. It will not 

 flower before the second season. Having been found in Texas or 

 provinces more to the southward, it cannot be regarded as per- 

 fectly hardy. It is really a showy although a straggling plant, 

 and well suited for decorating mixed beds of flowers, or the skirts 

 of a plantation in the autumn. 



8. Oncidium tenue. Lindley, supra, vol. iii. p. 76. 

 Var. grandifiorum. 



Received from G. U. Skinner, Esq., in April, 1849, from 

 Guatemala. 



This has so very much the structure of Oncidium tenue that it 

 can only be regarded as a variety ; but it is one of greater 

 beauty than the original. The panicle is much more branched ; 

 the flowers are larger, paler, with two distinct triangular spots at 

 the base of the lip instead of broken blotches. The wings of the 

 column are, moreover, strongly toothed, and the base of the lip 

 is wider. The singular thinness of the pseudo-bulbs and the
