A47A87B5FF971E60FFBFFB496254FC40.taxon	etymology	Etymology. — This species epithet honors Dr. Bruce F. Hansen (USF), a Neotropical Apocynaceae specialist who made the revision of Forsteronia (unpublished) in 1985. Several new taxa were published recently (Hansen & Morales 2019). For many years Bruce was the curator of the USF herbarium in Tampa (the second largest in Florida) and the leading authority of the Atlas of Florida Plants. He did fieldwork in the United States, Mexico, the Caribbean, and Ecuador and is the senior collector on more than 8500 collected specimens. I appreciate his support for several years.	en	Morales, J.

A47A87B5FF9C1E6EFF97FE39619DFD33.taxon	discussion	Discussion. — Mandevilla pristina is morphologically similar to M. assimilis (K Schum.) J. F. Morales, but differs by its leaf blades with domatia along the midrib abaxially (vs. domatia lacking) and floral bracts 10 – 120 mm long (vs. less than 6 mm). It was previously considered to be endemic to Perú (Morales 2007 c).	en	Morales, J.

A47A87B5FF9C1E6FFF97F9C763EAFE6E.taxon	discussion	Discussion. — Type collections of Mandevilla sagittarii and M. dodsonii exhibit no noteworthy differences (Morales, 2011). Gentry (1981) cited M. dodsonii being related to M. hirsuta, differing by its corolla tube shape, but no relationship or inference with M. sagittarii was made. Some gatherings identified as M. dodsonii reported white or cream flowers instead of the yellow corolla typically found in M. sagittarii. However, the same variation is found in some other species of the exothostemon group (e. g, M. hirsuta).	en	Morales, J.

A47A87B5FF9D1E6FFFBFFE1461DEFD25.taxon	discussion	Discussion. — Based on Holm-Nielsen et al. 26516 (AAU), Potgieter and Zarucchi (1999) reported this species for Ecuador. However, this specimen must be identified as Mandevilla inexperata J. F. Morales, an endemic Ecuadorian species (Morales 2007 b).	en	Morales, J.

A47A87B5FF9D1E6FFFBFFD1E6467FBB0.taxon	discussion	Discussion. — Potgieter and Zarucchi (1999) cited this species as native based on Steyermark 53292. However, this specimen was obtained from a market, as stated on the label [‘ cultivada y vendida en un mercado’ / cultivated and sold in a market]. I have not seen any other specimens to confirm that M. laxa is native to Ecuador. In Perú, gatherings from this species have been collected in the southwestern area of the country. Based on the available evidence, M. laxa should be excluded from the native flora of Ecuador.	en	Morales, J.

Mandevilla riparia was cited by Potgieter & Zarucchi (1999), but the voucher specimen and other gatherings with the same name in Ecuadorian herbaria correspond to M. assimilis (Morales 2005 c).	en	Morales, J.
