Ocorrência do órgão cupuliforme com bordos pelífenos, no colo dos "seedlings" de algumas MyrtaceaeResumo
After verifing the presence of the cupuliform organ on the seedlings from 105 species of Eucalyptus (ACCORSI, 1955-56), the author concluded that it is a morphological characteristic of the genus, which is peculiar to the plants only in first stages of their life. In this paper, the author resumes his study carried out on 20 species of Myrtaceae, distributed among 13 genus and he could certify, until now, that, in relation to the cupuliform organ, they may divided in three groups: 1.° Group - Without cupuliform organ 1.

ABSTRACT
After verifing the presence of the cupuliform organ on the seedlings from 105 species of Eucalyptus (ACCORSI, 1955-56), the author concluded that it is a morphological characteristic of the genus, which is peculiar to the plants only in first stages of their life.
In this paper, the author resumes his study carried out on 20 species of Myrtaceae, distributed among 13 genus and he could certify, until now, that, in relation to the cupuliform organ, they may divided in three groups:
1.° Group - Without cupuliform organ
1. Campomanesia aurea Berg
2. Eugenia campestris DC.
3. Eugenia tomentosa Camb.
4. Eugenia uniflora L.
5. Myrciaria edulis Berg
6. Myrciaria trunciflora Berg
7. Pitangueira-gigante - As it was difficulty to identify this species, I use its common name.
2.° Group - With rudiment of cupuli
orm organ
1. Eugenia uvalha Camb.
2. Jambosa vulgaris DC.
3. Myrciaria cauliflora Berg
3.° Group - With full cupuliform organ
1. Amomyrtus luma (Mol) Legr. et Kaus.
2. Blepharocalyx angustifolius Berg
3. Britoa acida Berg
4. Callistemon speciosus DC. o. Callistemon viminalis Cheel.
6. Feijoa sellowiana Berg
7. Myrceugenia glaucescens (Camb.) Legrand
8. Myrrhinium rubriflorum Berg
9. Psidium guayava Raddi
10. Psidium littorale Raddi
During his observations, he could identify also in many, seeds an "operculum", further observations about it will be published opportunely.
