Hazen, Jacob and Willem van, florists of Leyden

"Extracts from the literary and scientific correspondence 
of Richard Richardson", ed. by D. Turrer (Yarmouth, 
1835), contains letters from Gronovius referring
to a gardener named "Haze" or "Van Hasen". On July 22d,
1738 (p.365), he writes that he has seen Jacob Haze about
bulbous roots wanted by Richardson, also about getting
Haze to supply him with a camphor tree. On July 29th
(p.374) he says "Van Hasen hath collected all the roots
which you want", mentioning various bulbs and tuberous
plants, and on Sept. 2d (p.375) says "Haze" is sending
layers of Laurus Aldini. Altho no connection is indicated, 
it would seem as if Jacob must belong to the same florist 
family as Willem van Hazen, who is probably the subject 
of the later notes in the same work on a certain "Wm.
Van Haren" of Leyden. They occur in letters to Richardson
from Thomas Khowlton, who was a poor speller, hence the
substitution of an "r" for a "z" in the surname may have
been due either to Knowlton’s own spelling or to illegible
writing or careless transcription of the name. On Nov.
13th, 1750 (p.406) Khowlton writes of sending a Hernandia
of his own raising to "Van Haren at Leyden", and on March
8th following (p.409) he says: "Mr. Van Haren of Leyden
has lately published a Catalogue of his garden, stove- and
green-house plants ... named, after Dr. Boerhaave and Van
Royen, Flora Leidensis". Khowlton says this catalog is
said to contain nearly 850 sorts of plants. (MFW)
