Dr Graham's List of Rare Plants. 1 51 
rolla subringent ; tube pale red, 
secreting a large quantity of ho- 
ney, dilated at the base, mouth 
compressed, oblique ; limb bright 
red, 5-cleft, segments obtuse, 
closely reflexed upon the tube 
and outer calyx. Stamens in- 
cluded, 4 fertile, didynamous, 1 
abortive, varying in length, and 
adnate towards its base with 
the tube of the corolla behind 
the style ; filaments inserted in- 
to the corolla where it begins to 
dilate at the base, stout, red, 
compressed ; anthers large, yel- 
low, ciliated, mucronate at the 
base, mucros red, smooth. Ger- 
men yellow, urceolate, beaked, 
beak green. Style rather slen- 
der, longer than the filaments, 
white, compressed, bent to a 
right angle near the top ; stigma 
white, cleft, sub-exserted. 
This species, as well as some of 
those lately published, shews 
that the form of the corolla va- 
ries greatly, and seems to indi- 
cate the propriety of striking it 
cut of the essential generic cha- 
racter. This species also shews 
that in the genus there is a want 
of uniformity of calyx. 
Tulbagia alliacea. 
Valisneria spiralis (foem.) 
This most desirable plant was in- 
troduced into the garden from 
the St Lawrence, in the neigh- 
bourhood of Sorell, 160 miles 
above Quebec, by the kindness 
of the Countess of Dalhousie.

JL HE journal, from which the following monthly results are 
extracted, is kept about SO feet above the level of the sea, 
and a few hundred yards distant from it. The Thermometer 
is registered at 9 a. m. and 9 p. m. ; the Barometer at 9 a. m. 
Noon, 4 p. m. and 9 p. m. ; the Bain-Gauge and Wind-Vane at 
Noon. The Hygrometrical observations are made by means of 
two Thermometers, one of which has its bulb covered with silk, 
and moistened with water ; their indications are registered at 
noon.
