Synonyms:Pilocarpus parviflorus Nees & Mart., Pilocarpus subcoriaceus Engl., Pilocarpus ypanemensis Engl., Pilocarpus spicatus var. subcoriaceus Engl. ex Duval
Description:Variety Description - Vegetative parts glabrous, or branchlets, petioles, and (mainly) base and costa of the leaves pubescent with spreading hairs to 0.05(-0.1) mm. Racemes to 1 cm wide, glabrous or pubescent with spreading hairs to 0.1 mm. Pedicels 0-3 mm long and 0.5 mm thick, in fruit up to 4(-6) mm long. Flowers 5-merous, rarely some 4-merous, 4.5-6 mm in diam.; petals 2-3 × 1-1.9 mm; filaments truncate or obtusish at tip, 1.5-2.4 mm long; anthers recurved; disc 0.3-0.6 mm high and 1.4-1.8 mm in diam..
Discussion:Pilocarpus subcoriaceus Engler cannot be maintained as a separate taxon. The differences described by Engler vary and occur also in many specimens certainly belonging to var. spicatus. The pedicels e.g., measure between 0 and 2 mm, and these sizes are not consistently correlated with other characters. The leaves of the syntypes of P. subcoriaceus are chartaceous or subcoriaceous, and subcoriaceous leaves were also found in plants belonging to var. spicatus with pedicels 1.5-2 mm long. The plants grow under the same conditions and in the same general region. Geiger (1897: 414) already suggested synonymy but in absence of ample material he did not combine them.The original syntypes of Pilocarpus ypanemensis Engler were destroyed in Berlin. Engler mentioned the two collections (Sellow 2174; 2178) in Fl. bras. 12(2) under P. spicatus. Duplicates of Sellow 2174 (PR, S, UC, all ex B) however, do not at all belong to Pilocarpus, nor to other Pilocarpinae. The duplicate in UC was misidentified by Engler as Esenbeckia riedeliana! In my opinion mistakes were made in B with these specimens. Sellow B 2178, c 2174 (S ex B) is now sterile but agrees in the vegetative parts with P. ypanemensis. Sellow 2178, fr (K ex B, 15 Nov 1907) agrees completely with the description of P. ypanemensis. This specimen I selected as lectotype; it was identified by Engler as P. spicatus. The description by Engler of P. ypanemensis, and the lectotype, agree fully with my concept of P. spicatus var. spicatus. Therefore I reduce P. ypanemensis to synonymy under this variety, as Geiger (1897: 414) suggested.Allemão 275, from Ceará, has large leaves with petioles to 5 cm long; this is the northernmost collection that is known.
