18 Notes on Pollen. By Worthington G. Snuith. 
from the pollen in this instance, for it agrees with the Caprifoliacez 
in its resemblance to Sambucus, Fig. 48 (but differs in the Snow- 
berry, Fig. 47, and the Honeysuckle, Fig. 5); and it agrees with 
Araliacez in resembling the Ivy, Fig. 73, and with the Saxifrages 
in being very much like the typical pollens found in this genus. 
Saxifraga umbrosa (which is characteristic) is shown at Fig. 49. 
Fig. 50 belongs to the Cedar of Lebanon, Cedrus Lnbany, 
Fig. 51 to Hcheveria secunda, Fig. 52 Arundinaria falcata (or, ac- 
cording to the ‘Gardeners’ Chronicle, June 24, 1876, p. 826, the 
plant in view is more correctly named Thamnocalamus Falconer), 
Fig. 53 Passiflora coelestina, Fig. 54 the Nettle, Urteca wrens. 
Turning now to the Gourd family, the pollen of the Melon 
(Cucumis melo) is illustrated at Fig. 55, and the Cucumber 
(C. sativus), Fig. 56. Judging from the plants themselves, and 
the great similarity in the form and size of the pollen, it would 
appear quite possible to get a hybrid between the Melon and the 
Cucumber ; and a well-known instance is on record of a supposed 
intermediate fruit produced naturally in Mr. Watson’s nursery at 
St. Albans. For an illustration and description of this fruit, 
engraved by the writer, see ‘Gardeners’ Chronicle,’ Oct. 4, 1873, 
p. 1335. The fruit was genuine, and was neither grafted or 
inarched, but whether or not it was a true hybrid, it certamly was 
a natural growth from the Cucumber plant. We believe the fruit 
illustrated damped off and rotted, and that no seeds were found 
inside. Before leaving the Gourds we may say the pollen of the 
Vegetable Marrow, Cucurbita ovifera, is totally different in 
character from the two last named, being two or three times larger 
in diameter, spherical in shape, and densely covered with spines. 
The Bryony of our hedges is again different from all three, but as 
large in size as the pollen of the Cucumber. 
The common Bitter-sweet, Solanwm dulcamara, bears very 
small pollen-grains, Fig. 57. The outline here engraved is a 
common form in the Solanum family. 
The Polemonium family is remarkable for its truly handsome 
pollen, that belonging to Phlow decussata is illustrated at Fig. 58 ; 
Cobxa scandens, belonging to the same family, has a pollen about 
ten times the bulk of Phlox, and with similar elegant hexagonal 
reticulations. 
Fig. 59 is a typical representative of the Amaryllis family in 
Crinum pratense, whilst Fig. 60 belongs to the common Snowdrop, 
Galanthus nivalis, and is the only departure from the typical form 
known to us in this family. Very little or nothing can be learned 
from a study of the pollens found in the genus Narcissus. The 
plants placed under this genus have been so often hybridized and 
have been so long cultivated, that the pollens (like the plants them- 
selves) vary exceedingly. One anther belonging to a Narcissus will
