    siuiilar, bydrocatarrhophicus, raeranaestheticus, spoH- dylexarthreticus; such words as these are inconvenient from <heir mere length.] 296. The specific character ought not to be embellished with the flowers of rhetoric, but natural and faithful. 207. The specific character admits neither comparatives nor superlatives. 298. The specific character must be expressed in positive terms, not in negative. Privatives are often unavoidable, although in some measure objectionable. Indivisum, inerme, enerve, avenium, acaulis are allowable; non papposum, non asperum, non bifidum, bad. [CuUen observes that distinctions deduced from the absence of symptoms are not good, but sometimes unavoidable. Synops- proleg. p. xxxvi.] 299. Resemblances, if ever employed for specific characters, must be striking and well known. As the ear, the finger, or the eye. 301. Adjectives must immediately follow their substantives. 303. Conjunctive particles are to be excluded from specific characters, except where they are necessary to the sense. 304. Successive adjectives are not to be separated by com- mas. We use a comma for separating the parts which are men- tioned, a colon for a subdivision of any part: thus, Bauhinia inermis, foliis cordatis semibifidis: laciniis acumiuatoovatis erectodehiscentibus. 305. A specific character must never contain a parenthesis, whether distinguished or not by the appropriate mark. A parenthesis is bad, as implying a defect of order. CHAPTER IX. Of varieties. S- 306. To the generic name and specific character the dis- tinction of a variety may be added, where it exists. Tlie knowledge of the varieties of plants is more important
