last year ; and it is weil deserving of culture by all persons possessing a 
stove. 
Callistachys linearis , Benth.; C. sordida , Graham (t. 3882). Great 
expectations were raised of this plant before it flowered, from the name 
of the crimson Callistachys having been inscribed on the paper of its 
seeds, when they were first received from Mr. Drummond, from the 
Swan River. The flowers, however, are not of a rich crimson, but 
partly yellow and partly red, neither colour being particularly bright or 
clear. It is a greenhouse plant, which may be planted out into the open 
ground during summer. 
Stylidium ciliatum , Lindl.; S. setigerum , : Dec. (t. 3883). A Swan 
River plant, with small, pale yellow flowers, which are more curious 
than beautiful. It is a new greenhouse perennial, but it is not worth the 
trouble of cultivating. The specific name alludes to the knobbed hairs 
which cover the whole of the flower-stalk and flowers, but which are so 
small that their curious construction cannot be seen without the aid of a 
microscope. There are said to be forty or fifty distinct species of 
Stylidium , all natives of the settlement of the Swan River. 
Pentstemon campanulatus , Willd.; Chelone campanulata , Cav.; C. an- 
gusiifolia , Humb. et Kunth. (t. 3884). An old plant, which, under the 
name of Chelone, was formerly well known in British greenhouses. The 
flowers are of a pale purple, tinged with yellow below. It is a native of 
Mexico. 
Epidendrum Grahami (t. 3885). A new Mexican orchideous epiphyte, 
belonging to the group Encyclium. The flowers are pretty, and the plate 
is very well executed. 
The Botanical Register for July contains— 
Angraecum bilobum (t. 35). A very pretty epiphyte, a native of the 
shore near Cape Coast Castle. “ The flowers grow in pendulous simple 
racemes, and are slightly but sweetly perfumed ; their colour is white, with 
a slight tinge of black.” It should be grown constantly in a moist heat, on 
a block of wood hung from the rafters of the house. Very little moss should 
be used, as too much is apt to make the tender part of the plant rot. 
Ipomoea batatoides (t. 36). Botanists have long been puzzled to decide 
what plant produces the purgative drug called Jalap. It has long been 
well known that the drug takes its name from the Mexican town Xalapa, 
and that it was the root of a plant; but the difficulty was to find what 
plant it was. At first it was thought to be the upright Marvel of Peru; 
then a species of Exogonium ; and lastly an Ipomoea, but of what species 
could not be exactly discovered. The fact is apparently that the roots of
