Diplandra Potamogeton. Bertero. This plant, the most inter- 
esting which | have met with, grows in the clear waters of the drains 
of Quinta, Corcolen and Taguatagua, and resembles a Potamogeton 
so closely that it can be distinguished only by its flower. It is dioe- 
cious ; the calyx tubular, very large, and the tube of the corolla more 
elongated, the anthers are twelve, and are inserted into the throat of 
the corolla, at the top of the tube. After fecundation, they are di- 
lated and take the form of a petaloid membrane. It is doubtless a 
new genus, and should be added to the family of the Naiades. 
Dipsacus Fullonum, LL. Carda, common on the banks of drains 
and in humid spots on the plain. ‘This plant has but little use at 
present, nor will it be an object of speculation until manufactories of 
cloth are established, which will not be until after the propagati 
the Merino sheep, which ought to do well in many parts of th 
tory of Chile. A 5 ae 
Dolichos biflorus, and D. sesquipedalis, L. are plants very little cul- 
tivated, The first should draw the particular attention of cultivators 
who would have another vegetable at their disposal in a country 
where this species of pulse is in general use.- Its legumes, when they 
are tender, form a delicate dish, and may be preserved throughout 
the year by salt, in well stopped jars, thus securing an excellent re- 
Source in winter. The plant which is cultivated in gardens under 
the name of ramilette—nosegay—is without doubt the D. lignosus, 
L.. Itis probable that Molina has described the same species, to 
Which he has given the name of D. funarius. The D. ruber, Jacq. 
(Dioclea Jacquiniana. D. C. Hymenospron rubrum. Spr.) is also 
Cultivated in some gardens, and is called enredadera, a 
g very vague 
appellation and applicable to an infinity of plants whose stalks inter- 
lace with the neighboring plants. The same use may be made of 
these two last species as was spoken of under the head of Convolvulus 
natia. Forst. Common on arid heights and on the sides of 
lotrents. ‘This very singular and pretty plant has no vulgar name. ' 
De Candolle places the Donatia in the family of the a age 
(Prodr. Vol. Ill, p. 351,) though he does not mention it’ among 
se he describes’ in that place. | Was it overlooked? 
Dothidea Spherioides. Fries. A very small moss common on 
the bark of the Populus dilatata, Ait. alamo, poplar, principally on 
the dead and half rotten branches. 
is Chilensis. D. C. This tree known by the name of Ca- 
nelo—cinnamon tree—is nearly related to the D. Winteri, Forst. 
and it appears to me difficult to separate it since the characters as-
