Karl Gustav Sanio
Prussian botanist (1832-1891)
Karl Gustav Sanio (5 December 1832 – 3 February 1891) was a Prussian botanist and served as a professor of botany at the University of Königsberg. He observed patterns in the growth of plant vasculature and wrote several articles on the organization of wood and cambium. He examined patterns in the size distribution of the xylem vessels in five statements known as Sanio's laws was also among the first to describe the formation of compression wood by conifers.
Life
Sanio was born in Lyck in a wealthy family and became interested in nature in the vast family estate. He studied botany under Ernst Meyer at the University of Königsberg and then moved to study medicine. He published his first note at the age of 24 on the spores of Equisetum. Unhappy with medical studies, he moved back to study botany at Berlin under Alexander Braun and Nathanael Pringsheim. He received a doctorate in 1858 and then taught botany after moving back to Königsberg. He suffered from a stroke on January 28, 1891 and was unconscious until his death on February 3.
Sanio's laws
In 1872 he published a series of observations on a pattern in the size of xylem tracheids, increasing in size from the top of a tree to a certain height after which they decrease again to the base of the tree.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 12, 2025. The linked authority identifier is Q3813045. The first chronological checks are 1832, 1891, 1858 and 1872.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
