Sanion.

/ˈsanɪəʊ/

Etymology: < the name of Gustav Sanio (1832–91), German botanist.

Botany.

†a. [First designated, as Sanio'sche balken, by C. Müller 1890, in Ber. d. Deutsch. Bot. Ges. VIII. 23.] Used in the possessive and with of to designate a thickening of the primary wall or medial lamella separating or enclosing pits in wood, esp. of the radial walls of tracheides in gymnosperms. Obsolete.

Sanio1891

1891 Jrnl. Royal Microsc. Soc. 488 ‘Sanio's Bands’ in the Coniferæ.—By this term (Sanioische Balken) Herr C. Müller proposes to designate the beams or thickenings commonly found in the xylem-elements, chiefly in the tracheids of Coniferæ.

1915 Jrnl. Linn. Soc.: Bot. 41 462 All the Indian species of Pinus show Sanio's rims.

1916 Ann. Bot. 30 425 Sanio's bars are small rods crossing the tracheides, cambium, and phloem elements in many conifers.

1920 Bot. Gaz. 70 431 Considerable importance was attached for some years to the presence or absence of ‘bars’ or ‘rims’ of Sanio.

1935 C. J. Chamberlain Gymnosperms xi. 245 A cytological study of the origin and development of the bordered pit and the bars and rims of Sanio would be interesting.

b. Sanio's law: any of a set of empirical results that describe the growth of tracheides in conifers.

Sanio's law1903

1903 Mudge & Maslen Class-bk. Bot. ii. 51 It follows from Sanio's law that the elements of the phloem and xylem, unless subjected to subsequent disturbances, should be arranged in radial rows.

1915 Bailey & Shepard in Bot. Gaz. 60 66 (heading) Sanio's laws for the variation in size of coniferous tracheids.

1915 Bailey & Shepard in Bot. Gaz. 60 70 It is evident from Table V that Sanio's second law is applicable to Picea rubens as well as to Pinus sylvestris.

1961 Forestry XXXIV. 125 The foundation of the study of tracheid and fibre-length variation was laid by Sanio (1872) who presented his results of studies on Scots pine (Pinus sylvestris) in a set of five conclusions which, for some time now, have been regarded as ‘Sanio's Laws’.

1975 S. Carlquist Ecol. Strategies of Xylem Evol. 5 The variations noted in Sanio's laws have been confirmed for a number of conifers and dicotyledons.
