chinensis var. procumbens, Xo. 11. Under this 

 name apparently three different forms have been con- 

 fused; these are: 



chinensis var. japonica, Vilm. (J. japonica, Carr.). 

 A dwarf shrub with foliage mostly of the juvenile type; 

 of this two forms are in cult. : Var. japonica aurea, Bean 

 (J. chinensis var. procumbens aurea, Beiss.). Of more 

 spreading habit with a few long branches, the young 

 growth golden yellow. Var. japonica aureo-varie- 

 gata, Bean (J. chinensis var. procumbens aiureo- 

 i*aritg.aia, Beiss.). Of more compact and upright habit, 

 the young growth variegated with golden yellow. 



chinensis var. Sargentii, Henry. A prostrate form 

 with long spreading stems, the lateral branchlets 

 ascending, forming dense mats; Ivs. on young plants 

 almost all acicular and grass-green, on fruiting plants 

 all or nearly all scale-like and bluish green. Japan. 

 As a ground-cover this juniper is one of the most valua- 

 ble. Intro, in 1892 to the Arnold Arboretum by Sargent 

 and subsequently distributed as J. chinensis var. 

 procumbent. 



procumbens, Sieb. (J. chinensis var. proc&mbens, 

 Endl.). Low prostrate shrub with the branches ascend- 

 ing at the ends: Ivs. bluish green or glaucous, all acicu- 

 lar. in 3's. lanceolate, pungent, with a broad white 

 band above divided near the apex by the green midrib: 

 fr. not known. Japan. Closely related to J. squamata 

 from which it may be distinguished by the branchlets 

 being glaucous-white on the edges of the pulvini. 



LARIX. Page 1823. 



The hybrid between Larix decidua and L. leptolepis 

 mentioned under L. decidua has been named L. hybrida. 

 Its Ivs. are much like those of the L. leptolepis; the 

 mature branchlets are light brownish yellow and 

 slightly bloomy. 



LITHOCARPUS (literally stone fruit). Fagaceje. The 

 article Pasania (page 2479) is to be referred to this new 

 entry, as Lithocarpus is the older name and is the ten- 

 able one under the rules (see note in Sargent, PL Wil- 

 son. III. 205). Of Lithocarpus the following species are 

 known to be in cult: 



densiflfira, Rehd. (Pasania densiflora, Vol. V, p. 

 2479). 



cleistocarpa, Rehd. & Wilson (Quercus cleistocdrpa, 

 Vol. V, p. 2890). 



cornea, Rehd. (Pasania cornea, VoL V, p. 2479). 

 glabra, Rehd. (Pasania glabra, p. 2479). 

 Henryi, Rehd. & Wilson (Quercus Henryi, p. 2890). 

 thalassica, Rehd. (Pasania thalassica, p. 2479). 



LYSIMACHIA. Page 1935. 



japonica, Thunb. Annual : st . slender and decumbent, 

 simple, villous or pubescent, the apex erect: Ivs. oppo- 

 site, petiolate, roundish and subcordate to ovate, obtuse, 

 entire: fls. 1 or 2 in the axils, the peduncle shorter than 

 the Ivs. and reflexed in fr.; corolla J^in. or less across, 

 yellow, the gland-dotted segms. oblong. In moist 

 places and about fields, Japan, China, India, to the 

 Philippines. Whether the creeping yellow-fld. plant 

 listed under this name is the true L. japonica is appar- 

 ently }-et to be determined. 



NEPHROLEPIS. Page 2131. 



To supplement the original account of Nephrqlepis, 

 there are published herewith revised lists of varieties. 

 The first list (A) represents the forms now growing in the 

 living collection of the Brooklyn Botanic Garden (1916- 

 1917). It may be accepted as accurate as far as it con- 

 cerns the varieties of N. exaUata. With respect to the 

 varieties of species other than A". exaUata, no assurance 

 of accuracy can be given. The proper classification of the 

 wild forms of Nephrolepis is one of the most difficult 



Eroblems in fern taxonomy, and with the inclusion of 

 orticultural forms the difficulty is increased. The 

 second list of names represents those forms which 

 it has not yet been possible to secure for cultivation 

 at the Botanic Garden. They are listed here merely 

 to make the list of named forms as complete as pos- 

 sible. Most of the list was published in "Horticul- 

 ture," October 28, 1916, accompanied by names of 

 originators. 



Regarding the other forms, it may be said that for 

 American florists the Exaltata group includes practi- 

 cally all forms of commercial value. All these would be 

 classed as greenhouse forms. Most of the species and 

 varieties other than Exaltatas are stove forms. A few, 

 especially the forms of A", cordifolia (including A", tube- 

 rosa, a synonym), and N. pectinata, will stand as much 

 cold as the Exaltata varieties. Many of them are worth 

 a place in a collection, but in general they dp not make 

 the many-leaved bushy plants so much prized by the 

 American grower. 



It may be noted that a form of A*, cordifolia is appar- 

 ently invariably now being grown and offered in the 

 United States as N. exaUata. The true N. exaUata is 

 really a very different form, more like A*, bpstoniensis, 

 but easily distinguished by its greater stiffness and 

 fewer leaves. Another point of distinction between the 

 Exaltata group and the other is that, with the excep- 

 tion of N. exaUata itself, none of this group is spore- 

 fertile. Microscopic examination shows no fertile 

 spores, but does show apparently abortive sporangia. 

 It is practically useless, therefore, to attempt to raise 

 these from spores. Notwithstanding this statement, it 

 may be noted that several widely separated raisings 

 have been reported in which the sporelings showed 

 great variation, and it is not at all impossible that a 

 fertile variety might develop from any one of the 

 forms. Practically all the forms of other species (not 

 A*. exaUata) are spore-fertile, and may be readily 

 raised in this way. In fact most of the new horticultural 

 varieties in Group AA are reported as having originated 

 from spores. 



Finally, in Group AA, there are listed below a number 

 of names for which no plants have been yet secured. 

 They are probably mostly if not all of English origin, 

 and likely to fall in the group of varieties of species 

 other than N. exaUata.
