Shows that bees fertilize the flowers.

W: T. (2427) 
Henslow,G: Note on the structure of genista 
tinctoria, as apparently affording facilities 
for the intercrossing of distinct flowers. 
(Journ. Linn. soc., Bot., 16 Apr. 1868, v. 
10, p. 468, 15 cm.) 
Shows that the flowers are self sterile; but had no 
opportunity to observe the insects which fertilize them. 
W:; T. (2428) 
Henslow. G: Note on the structure of zvdz- 
gofera, as apparently offering facilities for 
the intercrossing of distinct flowers. With 
additional notice of Dr. Hildebrand’s paper 
on medicago, tndigofera and cytisus, in the 
Botanische Zeitung, March 1866; and a 
communication from Mr. Darwin on the 
‘common broom, cyfésus scoparius. (Journ. 
Linn. soc., Bot., 19 Apr. 1866, v. 9, p. 355- 
358.) 
Describes the actions of bees while visiting the last- 
named species, and shows their probable influence in 
crossing the others. W: T. (2429) 
Henslow, G: Note on the structure of 
medicago sativa, as apparently affording 
facilities for the intercrossing of distinct 
flowers. (Journ. Linn. soc., Bot., 16 Noy. 
1865, V. 9. p- 327-329.) 
Only observed apis mel/ifica on the flowers, and these 
insects did not have power to set free the staminal tube. 
: W: T. (2430) 
Hepworth, J. Notes on the rhododendron. 
(Science gossip, 1878, p. 177-178.) 
Describes the flowers of rhododendron and shows 
their adaptation to bees, as pollinating agents, which 
have been observed to visit them, WOT. (24am) 
Hildebrand, Friedrich, see HENsLow, G:, Note on the 
structnre of izdigofera ... [Rec., 2429]. 
Hildebrand, Friedrich. Ueber die Befruch- 
tung von aristolochia clematitis und einiger 
anderer Aristolochiaarten. (Pringsheim’s 
Jahrbiicher fiir wiss. Botanik, 1866, v. 5, 
P- 343-358; pl. 43-) 
Describes the attraction of small flies into the flowers 
of artstolochia and their detention there while the flower 
changes functionally from pistillate to staminate, when 
they are released, pollen-laden, to enter another newly 
opened pistillate flower, where they go through the same 
performance. W: T. (2432) 
Hildebrand, Friedrich. Ueber die Befruch- 
tung von asclepias cornuti. (Bot. Zeitung, 
30 Nov. 1866, v. 24, p. 376-378.) 
Shows how the flowers are fertilized by apzs mellifica 
and bombus; notes the occasional capture of the former 
by the flowers. W: T. (2433)

Hildebrand, Friedrich. Ueber die Befruch- 
tung der Salviaarten mit Hulfe von Insek- 
ten. (Pringsheim’s Jahrbiicher fiir wiss. 
Botanik, 1865, v. 4, p. 451-478, pl. 33.) 
Describes the flowers of 14 species, taken from most 
of the large groups into which the genus salvia is 
divided. The species studied show a very interesting 
gradation between species capable of self-fertilization, or 
of close-fertilization by insects, and such as are self- 
sterile, and adapted to crossing by insects [and birds].

Hildebrand, Friedrich. Ueber die Bestiiu- 
bungsvorrichtungen bei den Fumariaceen. 
(Pringsheim’s Jahrbucher ftir wiss. Botan- 
ik, 1869, v. 7, p. 423-471, pl. 29-31.) 
Describes the structure of the flowers of fumartaceae, 
and the pollination of many by insects.

Hildebrand, Friedrich. Die Geschlechter-

setz der vermiedenen und unvortheilhaften 
stetigen Selbstbefruchtung. Mit 62 Figuren

Rev., by F. Delpino, entitled “Sull’ op- 
era "La distribuzione dei sessi nelle piante 
e la legge che osta alla perennita della 
fecondazione consanguinea’... Note cri- 
tiche.” (Atti della soc. ital. di sci. nat. 
[Milano], 1867, v. 10, p. 271-303.) 
Shows the adaptation of many flowers to cross-fertil- 
ization by insect agency. W: T. (2436)

wendigkeit der Insektenhiilfe bei der Be- 
fruchtung von corydalis cava. (Jahrb. 
wiss. Botanik, 1866, v. 5, p. 359-363.) 
Shows that although the stigma of a given flower is 
well covered with pollen which emits its tubes, no fruit 
is produced unless pollen is brought from another flower. 
This is effected by bees. W: T. (2437) 
Hildebrand. Friedrich. Ueber die Vorrich- 
tungen an einigen Bliithen zur Befruchtung 
durch Insektenhiilfe. (Bot. Zeitung, 9 Mar. 
1866, v. 24, p. 73-78, pl. 4.) 
Describes the adaptztion of pedicularts sylvatica, 
indigofera, medicago, cytisus, lopezia coronata, schiz- 
anthus pinnatus and siphocampylus bicolor to cross- 
fertilization by the aid of insects. We Te, (2aa8)

of aristolochia grandifiora. (Amer. nat., 
May 1877, Vv. 11, p. 303-304.) 
A record of observations in Jamaica. Finds this— 
like other species of the genus —an admirable fly-trap, 
detaining insects which enter the flowers in the first ( @ ) 
stage of development until after the stigmas have with- 
ercd and the stamens matured, when they are allowed 
to escape, pollen-laden, to effect the fertilization of 
other and younger flowers. W: T. (2439)
