First 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 Red Cedar. The older wood in the centre is of a dark red colour, whilst the 

 newer and outer is white. It is very dry and splintery, but continues a long time undecayed, when 

 covered with earth. The trees grow large, straight, and tall, sending off their branches at 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, MSS. Perhaps Pinus taxifolia, Lamb, is not distinct. 

 ft.iAJ'f*** 1. " Pinus rigida?" 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 large 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, MSS.— Of this, we regret to say, no specimen exists in the Collection.

 longwnbus, tubo floris imberbis fmformi, capsula obtuse hexagona.— Marsh. Bieb. Fl 

 Tour. Caucas. 



The Californian specimens exactly accord with Caucasian ones we possess from Dr. Fischer, and from 

 Ehzabethgorod from Mr. Prescott. Perhaps I. verna, Pursh, is not distinct.

 floris imberbis subaequantibus. Spr.~Willd. Sp. PI. v. 1. p. 237. Pursh, Fl. Am. v. 1. p. 30.
