Appendix. By S. Polgár. 1. Solanum allanii n.sp. (There occur numerous forms of Solanum in New Zealand at present loosely lumped under S. nigrum, and there has long been doubt how far they are indigenous and how far introduced. In an attempt to straighten out the situation I have sent a series of specimens and seeds to Dr. Polgár, of Györ, for his critical examination. From his study of the herbarium material and of plants raised from the seed he has found that while S. nigrum, in several varieties, certainly occurs in New Zealand, there are several allied but distinct species as well. Prior to a complete revision of the group Dr. Polgár has kindly supplied the following diagnosis of two of the new species. H. H. A.) “Suffrutex, sed iam primo anno florens, metralis vel altior (primo anno), ab imo valde ramosus. Caulis basi (primo anno) c. 1 cm. diam., infra lenticellis instructus, interdum subdichotome ramosus rami erecti-patuli vel patentissimi, nonnumquam fere geniculatim flexuosi, subangulati, lineis decurrentibus valde sparse

(Herbarium of the Plant Research Station, Wellington, New Zealand, no. 8954.) Species ob crassitudinem styli, dehiscentiam anthemarum, structuram stigmatis notabilis. Habitus locum natalem aridum videtur indicare. Affines videntur: S. apopsilomenum Bitter e Nova Zelandia (Sol. Nova X, no. 208), quod tamen floribus multo majoribus, forma et dehiscentia antherarum etc. differt. S. depilatum Bitter e Madagascar austr. (loc. cit., no. 207) differt forma foliorum et styli.
