F irst detected by Mr. Menzies; and if we are correct in referring the plant to the M, Xalapensis, it is a
native of Mexico also.

“ The native name is R e d Cedar. The older wood in the centre is of a dark red colour, whilst the
newer and outer is white. I t is very dry and splintery, but continues a long time undecayed, wheu
covered with earth. The trees grow larçe, straight, and tall, sending off their branches a t right angles.
They decorate the valleys and tops of the mountains, and are the most general trees on the shores of the
Bay of San Francisco. I was informed that there are trees of this species in the vallies between Santa Clara
and Santa Cruz, 150 feet high, one of which was 25 feet in circumference. When young, the wood is so
full of sap, as to make it sink in salt water.”—Collie, M S S . Perhaps Pinus taxifolia. Lamb, is not distinct.
1. “ Pinus r ig i d a r Mill.
“ Black or pitch pine.—Abundant on the granite hills close to the sea, on the South East side of the
Bay of Monterrey, giving the name of Pine Point to the southern part of the bay. The trees grow to
the height of 60 or 80 feet, are very straight, and of laigfe diameter, rendering them very fit for masts.
They are also used for rafters, but decay very soon when covered with earth. They contain much resin!”
Collie, M S S .—Of this, we regret to say, no specimen exists in the Collection.

The Californian specimens exactly accord with Caucasian ones we possess from Dr. Fischer, and from
Elizabethgorod from Mr. Prescott. Perhaps I. vema, Pursh, is not distinct.

Of this there appears to have been only one specimen gathered. The locality from which the specimens
figured in the Botanical Magazine were derived, is unknown ; Mr. Ker having merely supposed it to be
Virginia and Carolina, from confounding it with Michaux’s plant.

Of this, there is only one specimen, but quite agreeing w ith the character.

1. Phalaris Californica; panicula subspiciformi oblonga, glumis patentibus concavis
ovato-lanceolatis ü'inervosis, glumellis pubescentibus, rudimentis duobus oppositis gluniellulæ-
formibus pilosis e basi callosa subpediceUatis, vaginis foliorum arctis, ligula oblonga
elongata.
This, as far as regards the panicle and habit of the plant, is intermediate between the true species of
Phalaris, and Digraphis of Trinius. In character, it approaches most to the latter, especially by the shape
of the rudimentary florets. The pauicle is about the size and form of that of Phalaris Canariensis, or Ph.
bulbosa, hut it is not nearly so compact.

The greater breadth of the fronds and of the segments, and the oval sori, readily distinguish this from
P. migare.
