botanical name unknown (but most commonly it is Buxus sempervirens)
There are at least 88 species from 41 genera that have the word boxwood as all or part of one or more of their common names and I have no idea which of them are represented on this page except as specifically noted.
That said, I would add that "boxwood" generally means Buxus spp. (with Buxus sempervirens being the most common) but there are other woods, particularly castello boxwood (Calycophyllum multiflorum) that are commonly sold as boxwood in the USA. Buxus spp. species are generally very heavy/dense (60 to 70 lbs/cuft) and very stable and were long used for precise engineering rulers because of the stability. I went to an engineering college in the 60's and we all had triangular boxwood rulers. Buxus sempervirens grows as a shrub or small tree so is available only in very modest sizes.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
both sides of a sample plank of European boxwood / Buxus sempervirens --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site.

This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. This sample is segmented, edge-grain butt-joined but the two pieces are possibly even from the same plank, so I don't consider that a big deal for the sample quality.

all 4 sides of a sample plank of boxwood --- HUGE enlargements are present. This sample was contributed to the site by Martin (lonewolf) of Wood Barter, whom I thank for the contribution. I believe this is Buxus sempervirens.
both sides of a sample plank of boxwood / Phyllostylon brasiliensis --- HUGE enlargements are present. This sample was loaned to me by Mark Peet whom I thank for this and other contributions to the site. This species is normally called South American boxwood. The black streak seems to be clearly the result of an ambrosia beetle's having eaten into it.

NOT A RAW WOOD COLOR --- both faces of this sample have a light coat of clear paste wax both sides of a sample plank of boxwood / Buxus sempervirens --- HUGE enlargements are present. This sample was loaned to me by Mark Peet whom I thank for this and other contributions to the site. Mark tells me the "heartwood" and the dark lines in this are likely a response to harsh weather conditions, not actual heartwood.

both sides of a sample plank of figured Castello boxwood / Calycophyllum multiflorum --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. The "figure" in this is a curl that is so mild as to be nearly invisible.

both sides of two book matched planks of Castello boxwood / Calycophyllum multiflorum --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. For more detail, see the smaller sample directly below which was cut from one of these.

both sides of a sample plank of ivorywood / Calycophyllum multiflorum --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. Although the vendor of this sample has it legitimately designated as ivorywood, that name leads to confusion because it is used for a number of woods whereas the designation of Castello boxwood is unique.

both sides of a sample plank of boxwood. HUGE enlargements are present. This sample was contributed to the site by Tom King, whom I thank. When I got this, I thought it was olive but the end grain match with boxwood is excellent and that with olive not so much.
