I can find no characters by which to distinguish Grislea compacta 
Rusby (Smith 1875), which is an excellent match of Linden 10 from 
Caracas. Smith 1874, which Dr. Rusby has named G. secunda, 
appears to be merely a broad-leaved form of the same species. The 
genus Grislea is attributed by Koehne {ll. cc.) to “ Loefl. in Hort. 
Cliff. 146 (1737),” at which date Loefling was only eight years old. 
Apparently Koehne did not study the description in Hort. Cliff. : the 
sentence “ Racemus ramos terminans, simplex, extrorsum flexus, 
longitudine foliorum, cui a basi ad apicem insident numerosi flores 
pedicellis longitudine calycis, sursum uno versu flexi omnes ” is 
irreconcilable with the Lythraceous plant; the latter has axillary 
compound inflorescences much shorter than the leaves, and the 
flowers are not secund. 
FORSSKAL’S HERBARIUM. 
In his book Naturforskeren Fehr Forsskal (1918), of which a 
short notice appeared in this Jounal for that }^ear (p. 357), Dr. Carl 
Christensen promised to give an index to the Flora JEgyptiaco- 
arahicce (1775) ; this was delayed on account of the cost of printing, 
but is now published in Dansk Bot. Archiv. vol. iv. n. 3 ; 1922. 
In order to perform his task thoroughly, Dr. Christensen has 
examined Forsskal’s Herbarium at the University of Copenhagen. 
This is now kept separately, and contains about 1300 specimens ; of 
the total number of plants described or mentioned in the Flora, about 
500 are represented in the Herbarium, including about 400 of the 
700 new species there described, besides numerous types of species 
founded by other botanists, chiefly by Vahl (in liis Symbolce Fo- 
taniccE ) andRottboll, on plants collected by Forsskal. His specimens 
had many vicissitudes; some sent by him to Copenhagen never 
reached their destination ; a parcel from Suez and others from Con¬ 
stantinople were lost; the plants from Yemen were brought by 
Niebuhr to India, and sent thence to Copenhagen, where they were 
not unpacked until 1767: “in 1772 they were removed to the Uni¬ 
versity, and placed under the care of Professor Rottboll, who at once 
began to describe some of them, especially the Cyperacece, but the 
bulk of the plants was not determined.” In Y916 Dr. Christensen 
undertook the rearrangement of Forsskaks Herbarium, and discovered 
that numerous species redescribed by Vahl, including all the Com- 
positce and Fapilionaceee, were missing; most of these, however, 
were found in the General Herbarium of the University. It may 
be noted that the Department of Botany contains a large number of 
Forsskal plants, which formed part of the Banksian Herbarium. 
A memorandum by Robert Brown, dated March 26th, 1808, runs :— 
“ Forskael’s plants in Herb. Banks were received from Fabricius, 
then a professor at Copenhagen, and were laid in before Mr. Dryander 
came to England [1777]. Several of them have names not to be 
found in Forskael’s Flor., which Mr. Dryander supposes came with 
them as w r ell as the short descriptions which accompany a few of
