Type in Tonkin bamboo into the google search engine some time... you will see more listings for "Tonkin Cane" than you do Tonkin bamboo.
If that's the case Mike, Name them... The stuff doesn't grow big enough to be cost effective to make laminations.
There are many, many different species of bamboo.....Bamboo products are no different than many other hardwood products on the market today. Low quality products are often sold by small importers with one small shipment at a time as well as large corporations bringing in enormous shipments. Both have the objective of selling inferior bamboo cheaply. Always look for high quality bamboo products that are being sold by reputable specialized companies like Higuera Hardwoods.
Tonkin Bamboo or Tonkin Cane is the common name for the bamboo that is primary used for staking plants around the world. It is characterized by a thick wall and smooth nodes. The stakes are fairly straight and tan in color(color can vary slightly from pole to pole) and the nodes are fairly far apart. It tapers slightly from top to bottom(not uniform in diameter top to bottom). It only grows to a maximum diameter of about 2”. It is the ideal stake for staking plants although is has many other non agriculture or horticulture related uses. It is also used for building high quality fly fishing rods.
Moso Bamboo is characterized by it's thickness, minimum diameter is 2” and maximum diameter is 6”. It has a fairly thick wall. It is fairly straight (that doesn't mean perfectly straight) although it may have some slight bends to it. The nodes are closer together and more pronounced than Tonkin Bamboo. It is very strong and you cannot bend anything over 2” easily. It can be split in half. No two pieces are the same! The color is tan but the color may vary from pole to pole. The taper varies for pole to pole. It will have some scratches on the pole. At the nodes there is a thin membrane that sections off the bamboo. It is hollow between the nodes. Moso bamboo is the primary bamboo for making bamboo flooring....
